This document describes the generic installation procedure for GCC as well
|
|
|
|
as detailing some target specific installation instructions.
|
|
|
|
|
|
|
|
GCC includes several components that previously were separate distributions
|
|
|
|
with their own installation instructions. This document supersedes all
|
|
|
|
package specific installation instructions. We provide the component
|
|
|
|
specific installation information in the source distribution for historical
|
|
|
|
reference purposes only.
|
|
|
|
|
|
|
|
@emph{Before} starting the build/install procedure please check the
|
|
|
|
@ifnothtml
|
|
|
|
@xref{Specific, host/target specific installation notes}.
|

|

|
@end ifnotinfo
|
|
|
|
We recommend you browse the entire generic installation instructions before
|
|
|
|
you proceed.
|
|
|
|
|
|
|
|
The installation procedure itself is broken into five steps.

Please note that GCC does not support @samp{make uninstall} and probably
|
2001-05-12 00:10:54 +02:00
|
|
|
won't do so in the near future as this would open a can of worms. Instead,
|
|
|
|
we suggest that you install GCC into a directory of its own and simply
|
2001-06-01 20:08:19 +02:00
|
|
|
remove that directory when you do not need that specific version of GCC
|
|
|
|
any longer.

GCC is distributed via CVS and FTP tarballs compressed with @command{gzip} or
|
|
|
|
@command{bzip2}. It is possible to download a full distribution or specific
|
2001-05-12 00:10:54 +02:00
|
|
|
components.
|
|
|
|
|
|
|
|
Please refer to our @uref{http://gcc.gnu.org/releases.html,,releases web page}
|
|
|
|
for information on how to obtain GCC.
|
|
|
|
|
|
|
|
The full distribution includes the C, C++, Objective-C, Fortran, Java,
|
|
|
|
and Chill compilers. The full distribution also includes runtime libraries
|
2001-06-11 09:26:33 +02:00
|
|
|
for C++, Objective-C, Fortran, Java and Chill. (GCC 3.0 does not
|
|
|
|
include Chill. Releases before 3.0 do not include the Java runtime
|
|
|
|
library.) In GCC 3.0 and later versions, GNU compiler testsuites
|
|
|
|
are also included in the full distribution.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
If you choose to download specific components, you must download the core
|
|
|
|
gcc distribution plus any language specific distributions you wish to
|
2001-06-21 02:03:48 +02:00
|
|
|
use. The core distribution includes the C language front end as well as the
|
2001-05-12 00:10:54 +02:00
|
|
|
shared components. Each language has a tarball which includes the language
|
2001-06-21 02:03:48 +02:00
|
|
|
front end as well as the language runtime (when appropriate).
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
Unpack the core distribution as well as any language specific
|
|
|
|
distributions in the same directory.
|
|
|
|
|
|
|
|
If you also intend to build binutils (either to upgrade an existing
|
|
|
|
installation or for use in place of the corresponding tools of your
|
|
|
|
OS), unpack the binutils distribution either in the same directory or
|
|
|
|
a separate one. In the latter case, add symbolic links to any
|
|
|
|
components of the binutils you intend to build alongside the compiler
|
2001-06-13 15:07:28 +02:00
|
|
|
(@file{bfd}, @file{binutils}, @file{gas}, @file{gprof}, @file{ld},
|
|
|
|
@file{opcodes}, @dots{}) to the directory containing the GCC sources.

Like most GNU software, GCC must be configured before it can be built.
|
|
|
|
This document describes the recommended configuration procedure
|
|
|
|
for both native and cross targets.
|
|
|
|
|
2001-06-01 20:08:19 +02:00
|
|
|
We use @var{srcdir} to refer to the toplevel source directory for
|
|
|
|
GCC; we use @var{objdir} to refer to the toplevel build/object directory.
|
|
|
|
|
|
|
|
If you obtained the sources via CVS, @var{srcdir} must refer to the top
|
|
|
|
@file{gcc} directory, the one where the @file{MAINTAINERS} can be found,
|
|
|
|
and not its @file{gcc} subdirectory, otherwise the build will fail.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
First, we @strong{highly} recommend that GCC be built into a
|
|
|
|
separate directory than the sources which does @strong{not} reside
|
|
|
|
within the source tree. This is how we generally build GCC; building
|
2001-06-01 20:08:19 +02:00
|
|
|
where @var{srcdir} == @var{objdir} should still work, but doesn't
|
|
|
|
get extensive testing; building where @var{objdir} is a subdirectory
|
|
|
|
of @var{srcdir} is unsupported.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
2001-06-03 21:06:55 +02:00
|
|
|
If you have built GNU CC previously in the same directory for a
|
|
|
|
different target machine, do @samp{make distclean} to delete all files
|
|
|
|
that might be invalid. One of the files this deletes is
|
|
|
|
@file{Makefile}; if @samp{make distclean} complains that @file{Makefile}
|
|
|
|
does not exist, it probably means that the directory is already suitably
|
|
|
|
clean. However, with the recommended method of building in a separate
|
|
|
|
@var{objdir}, you should simply use a different @var{objdir} for each
|
|
|
|
target.
|
|
|
|
|
2001-06-01 20:08:19 +02:00
|
|
|
Second, when configuring a native system, either @command{cc} or
|
|
|
|
@command{gcc} must be in your path or you must set @env{CC} in
|
2001-05-16 16:57:06 +02:00
|
|
|
your environment before running configure. Otherwise the configuration
|
|
|
|
scripts may fail.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
To configure GCC:
|
|
|
|
|
|
|
|
@example
|
2001-06-01 20:08:19 +02:00
|
|
|
% mkdir @var{objdir}
|
|
|
|
% cd @var{objdir}
|
2001-06-02 20:21:37 +02:00
|
|
|
% @var{srcdir}/configure [@var{target}] [@var{options}]
|
2001-05-12 00:10:54 +02:00
|
|
|
@end example
|

|
2001-06-01 20:08:19 +02:00

|
GCC has code to correctly determine the correct value for @var{target}
|
2001-05-12 00:10:54 +02:00
|
|
|
for nearly all native systems. Therefore, we highly recommend you not
|
|
|
|
provide a configure target when configuring a native compiler.
|

|
|
|
|
|
|
@item
|
2001-06-13 15:07:28 +02:00
|
|
|
@var{target} must be specified as @option{--target=@var{target}}
|
2001-05-12 00:10:54 +02:00
|
|
|
when configuring a cross compiler; examples of valid targets would be
|
|
|
|
i960-rtems, m68k-coff, sh-elf, etc.
|
|
|
|
|
|
|
|
@item
|
2001-06-13 15:07:28 +02:00
|
|
|
Specifying just @var{target} instead of @option{--target=@var{target}}
|
2001-06-01 20:08:19 +02:00
|
|
|
implies that the host defaults to @var{target}.

Use @var{options} to override several configure time options for
|
|
|
|
GCC. A partial list of supported @var{options}:

Specify the toplevel installation
|
2001-05-12 00:10:54 +02:00
|
|
|
directory. This is the recommended way to install the tools into a directory
|
|
|
|
other than the default. The toplevel installation directory defaults to
|
2001-06-13 15:07:28 +02:00
|
|
|
@file{/usr/local}.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
2001-06-01 20:08:19 +02:00
|
|

We @strong{highly} recommend against @var{dirname} being the same or a
|
|
|
|

Specify the

|
|
|
installation directory for local include files. The default is
|
|
|
|
@file{/usr/local}. Specify this option if you want the compiler to
|
|
|
|
search directory @file{@var{dirname}/include} for locally installed
|
|
|
|
header files @emph{instead} of @file{/usr/local/include}.
|
|
|
|
|
|
|
|
You should specify @option{--with-local-prefix} @strong{only} if your
|
|
|
|
site has a different convention (not @file{/usr/local}) for where to put
|
|
|
|
site-specific files.
|
|
|
|
|
|
|
|
The default value for @option{--with-local-prefix} is @file{/usr/local}
|
|
|
|
regardless of the value of @option{--prefix}. Specifying
|
|
|
|
@option{--prefix} has no effect on which directory GCC searches for
|
|
|
|
local header files. This may seem counterintuitive, but actually it is
|
|
|
|
logical.
|
|
|
|
|
|
|
|
The purpose of @option{--prefix} is to specify where to @emph{install
|
|
|
|
GCC}. The local header files in @file{/usr/local/include}---if you put
|
|
|
|
any in that directory---are not part of GCC. They are part of other
|
|
|
|
programs---perhaps many others. (GCC installs its own header files in
|
|
|
|
another directory which is based on the @option{--prefix} value.)
|
|
|
|
|
|
|
|
@strong{Do not} specify @file{/usr} as the @option{--with-local-prefix}!
|
|
|
|
The directory you use for @option{--with-local-prefix} @strong{must not}
|
|
|
|
contain any of the system's standard header files. If it did contain
|
|
|
|
them, certain programs would be miscompiled (including GNU Emacs, on
|
|
|
|
certain targets), because this would override and nullify the header
|
|
|
|
file corrections made by the @code{fixincludes} script.
|
|
|
|
|
|
|
|
Indications are that people who use this option use it based on mistaken
|
|
|
|
ideas of what it is for. People use it as if it specified where to
|
|
|
|
install part of GCC. Perhaps they make this assumption because
|
|
|
|
installing GCC creates the directory.

|
|
|
Build shared versions of libraries, if shared libraries are supported on
|
|
|
|
the target platform. Unlike GCC 2.95.x and earlier, shared libraries
|
|
|
|
are enabled by default on all platforms that support shared libraries.
|
|
|
|
|
|
|
|
If a list of packages is given as an argument, build shared libraries
|
|
|
|
only for the listed packages. For other packages, only static libraries
|
|
|
|
will be built. Package names currently recognized in the GCC tree are
|
|
|
|
@samp{libgcc} (also known as @samp{gcc}), @samp{libstdc++} (not
|
|
|
|
@samp{libstdc++-v3}), @samp{libffi}, @samp{zlib}, @samp{boehm-gc} and
|
|
|
|
@samp{libjava}. Note that @samp{libobjc} does not recognize itself by
|
|
|
|
any name, so, if you list package names in @option{--enable-shared},
|
2001-06-21 17:25:56 +02:00
|
|
|
you'll only get static Objective-C libraries. @samp{libf2c} and
|
2001-06-13 09:11:59 +02:00
|
|
|
@samp{libiberty} do not support shared libraries at all.
|
|
|
|
|
|
|
|
Use @option{--disable-shared} to build only static libraries. Note that
|
|
|
|
@option{--disable-shared} does not accept a list of package names as
|
|
|
|
argument, only @option{--enable-shared} does.

2001-06-01 20:08:19 +02:00
|
|
|
assembler it finds is the GNU assembler. However, this does not modify
|
|
|
|
the rules to find an assembler and will result in confusion if found
|
2001-06-24 01:41:59 +02:00
|
|
|
assembler is not actually the GNU assembler. (Confusion will also
|
|
|
|
result if the compiler finds the GNU assembler but has not been
|
|
|
|
configured with @option{--with-gnu-as}.) If you have more than one
|
2001-06-01 20:08:19 +02:00
|
|
|
assembler installed on your system, you may want to use this option in
|

|
|
|
|
|
2001-06-24 01:41:59 +02:00

The systems where it makes a difference whether you use the GNU assembler are

|
@samp{hppa1.0-@var{any}-@var{any}}, @samp{hppa1.1-@var{any}-@var{any}},
|

|
|
|
|
On any other system, @option{--with-gnu-as} has no effect.
|
|
|
|
|
|
|
|
On the systems listed above (except for the HP-PA, for ISC on the
|
|
|
|
386, and for @samp{mips-sgi-irix5.*}), if you use the GNU assembler,
|
|
|
|
you should also use the GNU linker (and specify @option{--with-gnu-ld}).

Specify that stabs debugging
|
2001-06-01 20:08:19 +02:00
|
|
|
information should be used instead of whatever format the host normally
|
|
|
|
uses. Normally GCC uses the same debug format as the host system.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
2001-06-24 01:41:59 +02:00
|
|
|
On MIPS based systems and on Alphas, you must specify whether you want
|
|
|
|
GCC to create the normal ECOFF debugging format, or to use BSD-style
|
|
|
|
stabs passed through the ECOFF symbol table. The normal ECOFF debug
|
|
|
|
format cannot fully handle languages other than C. BSD stabs format can
|
|
|
|
handle other languages, but it only works with the GNU debugger GDB.
|
|
|
|
|
|
|
|
Normally, GCC uses the ECOFF debugging format by default; if you
|
|
|
|
prefer BSD stabs, specify @option{--with-stabs} when you configure GCC.
|
|
|
|
|
|
|
|
No matter which default you choose when you configure GCC, the user
|
|
|
|
can use the @option{-gcoff} and @option{-gstabs+} options to specify explicitly
|
|
|
|
the debug format for a particular compilation.
|
|
|
|
|
|
|
|
@option{--with-stabs} is meaningful on the ISC system on the 386, also, if
|
|
|
|
@option{--with-gas} is used. It selects use of stabs debugging
|
|
|
|
information embedded in COFF output. This kind of debugging information
|
|
|
|
supports C++ well; ordinary COFF debugging information does not.
|
|
|
|
|
|
|
|
@option{--with-stabs} is also meaningful on 386 systems running SVR4. It
|
|
|
|
selects use of stabs debugging information embedded in ELF output. The
|
|
|
|
C++ compiler currently (2.6.0) does not support the DWARF debugging
|
|
|
|
information normally used on 386 SVR4 platforms; stabs provide a
|
|
|
|
workable alternative. This requires gas and gdb, as the normal SVR4
|
|
|
|
tools can not generate or interpret stabs.

|
|
library, and exception handling for other languages like C++ and Java.

2001-06-02 15:59:52 +02:00

model available will be configured for use. Beware that on some

2001-06-16 00:25:18 +02:00

@item --enable-checking

|
When you specify this option, the compiler is built to perform checking
|
|
|
|
of tree node types when referencing fields of that node, and some other
|
|
|
|
internal consistency checks. This does not change the generated code,
|
|
|
|
but adds error checking within the compiler. This will slow down the
|
|
|
|
compiler and may only work properly if you are building the compiler
|
|
|
|
with GNU C. This is on by default when building from CVS or snapshots,
|
|
|
|
but off for releases. More control over the checks may be had by
|
|
|
|
specifying @var{list}; the categories of checks available are
|
|
|
|
@samp{misc}, @samp{tree}, @samp{gc}, @samp{rtl} and @samp{gcac}. The
|
|
|
|
default when @var{list} is not specified is @samp{misc,tree,gc}; the
|
|
|
|
checks @samp{rtl} and @samp{gcac} are very expensive.

The @option{--enable-nls} option enables Native Language Support (NLS),

2001-06-03 21:06:55 +02:00

If NLS is enabled, and if the host lacks @code{gettext} but has the

|
inferior @code{catgets} interface, the GCC build procedure normally
|

ignores @code{catgets} and instead uses GCC's copy of the GNU
|
2001-06-13 15:07:28 +02:00
|
|
|
@code{gettext} library. The @option{--with-catgets} option causes the
|
2001-06-03 21:06:55 +02:00
|
|
|
build procedure to use the host's @code{catgets} in this situation.

@cindex Installing GCC: Building
|
|
|
|
|
|
|
|
Now that GCC is configured, you are ready to build the compiler and
|
|
|
|
runtime libraries.
|
|
|
|
|
|
|
|
We @strong{highly} recommend that GCC be built using GNU make;
|
|
|
|
other versions may work, then again they might not.
|
|
|
|
|
|
|
|
(For example, many broken versions of make will fail if you use the
|
2001-06-03 00:33:30 +02:00
|
|
|
recommended setup where @var{objdir} is different from @var{srcdir}.
|
|
|
|
Other broken versions may recompile parts of the compiler when
|
|
|
|
installing the compiler.)
|
2001-05-12 00:10:54 +02:00
|
|
|
|
2001-06-03 00:33:30 +02:00
|
|
|
Some commands executed when making the compiler may fail (return a
|
|
|
|
non-zero status) and be ignored by @code{make}. These failures, which
|
|
|
|
are often due to files that were not found, are expected, and can safely
|
|
|
|
be ignored.
|
|
|
|
|
|
|
|
It is normal to have compiler warnings when compiling certain files.
|
|
|
|
Unless you are a GCC developer, you can generally ignore these warnings
|
|
|
|
unless they cause compilation to fail.
|
|
|
|
|
|
|
|
On certain old systems, defining certain environment variables such as
|
2001-06-13 15:07:28 +02:00
|
|
|
@env{CC} can interfere with the functioning of @command{make}.
|
2001-06-03 00:33:30 +02:00
|
|
|
|
|
|
|
If you encounter seemingly strange errors when trying to build the
|
|
|
|
compiler in a directory other than the source directory, it could be
|
|
|
|
because you have previously configured the compiler in the source
|
|
|
|
directory. Make sure you have done all the necessary preparations.
|
|
|
|
|
|
|
|
If you build GCC on a BSD system using a directory stored in an old System
|
|
|
|
V file system, problems may occur in running @code{fixincludes} if the
|
|
|
|
System V file system doesn't support symbolic links. These problems
|
|
|
|
result in a failure to fix the declaration of @code{size_t} in
|
|
|
|
@file{sys/types.h}. If you find that @code{size_t} is a signed type and
|
|
|
|
that type mismatches occur, this could be the cause.
|
|
|
|
|
|
|
|
The solution is not to use such a directory for building GCC.
|

|
|

|
2001-06-03 21:06:55 +02:00
|
|
|
When building from CVS or snapshots, or if you modify parser sources,
|
|
|
|
you need the Bison parser generator installed. Any version 1.25 or
|
|
|
|
later should work; older versions may also work. If you do not modify
|
|
|
|
parser sources, releases contain the Bison-generated files and you do
|
|
|
|
not need Bison installed to build them.
|
|
|
|
|
|
|
|
When building from CVS or snapshots, or if you modify Texinfo
|
|
|
|
documentation, you need version 4.0 or later of Texinfo installed if you
|
|
|
|
want Info documentation to be regenerated. Releases contain Info
|
|
|
|
documentation pre-built for the unmodified documentation in the release.

If you are short on disk space you might consider @samp{make
|
|
|
|
bootstrap-lean} instead. This is identical to @samp{make
|
|
|
|
bootstrap} except that object files from the stage1 and
|
2001-05-12 00:10:54 +02:00
|
|
|
stage2 of the 3-stage bootstrap of the compiler are deleted as
|
|
|
|
soon as they are no longer needed.
|
|
|
|
|
|
|
|
|
|
|
|
If you want to save additional space during the bootstrap and in
|
|
|
|
the final installation as well, you can build the compiler binaries
|
2001-06-01 20:08:19 +02:00
|
|
|
without debugging information with @samp{make CFLAGS='-O' LIBCFLAGS='-g
|
|
|
|
-O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap}. This will save
|
2001-05-12 00:10:54 +02:00
|
|
|
roughly 40% of disk space both for the bootstrap and the final installation.
|
|
|
|
(Libraries will still contain debugging information.)
|
|
|
|
|
2001-06-03 21:06:55 +02:00
|
|
|
If you wish to use non-default flags when compiling the stage2 and
|
|
|
|
stage3 compile, set @code{BOOT_CFLAGS} on the command line when doing
|
|
|
|
@samp{make bootstrap}. Non-default optimization flags are less well
|
|
|
|
tested here than the default of @samp{-g -O2}, but should still work.
|
|
|
|
In a few cases, you may find that you need to specify special flags such
|
|
|
|
as @option{-msoft-float} here to complete the bootstrap; or, if the
|
|
|
|
native compiler miscompiles the stage1 compiler, you may need to work
|
|
|
|
around this, by choosing @code{BOOT_CFLAGS} to avoid the parts of the
|
|
|
|
stage1 compiler that were miscompiled, or by using @samp{make
|
|
|
|
bootstrap4} to increase the number of stages of bootstrap.
|
|
|
|
|
2001-06-13 15:07:28 +02:00
|
|
|
If you used the flag @option{--enable-languages=@dots{}} to restrict
|
2001-05-12 00:10:54 +02:00
|
|
|
the compilers to be built, only those you've actually enabled will be
|
|
|
|
built. This will of course only build those runtime libraries, for
|
|
|
|
which the particular compiler has been built. Please note,
|
2001-06-01 20:08:19 +02:00
|
|
|
that re-defining LANGUAGES when calling @samp{make bootstrap}
|
2001-06-02 20:21:37 +02:00
|
|
|
@strong{does not} work anymore!
|
2001-05-12 00:10:54 +02:00
|
|
|
|
2001-06-03 21:06:55 +02:00
|
|
|
If the comparison of stage2 and stage3 fails, this normally indicates
|
|
|
|
that the stage 2 compiler has compiled GCC incorrectly, and is therefore
|
|
|
|
a potentially serious bug which you should investigate and report. (On
|
|
|
|
a few systems, meaningful comparison of object files is impossible; they
|
|
|
|
always appear ``different''. If you encounter this problem, you will
|
|
|
|
need to disable comparison in the @file{Makefile}.)

@section Building a cross compiler
|
|
|
|
|
|
|
|
We recommend reading the
|
|
|
|
@uref{http://www.objsw.com/CrossGCC/,,crossgcc FAQ}
|
|
|
|
for information about building cross compilers.
|
|
|
|
|
|
|
|
When building a cross compiler, it is not generally possible to do a
|
|
|
|
3-stage bootstrap of the compiler. This makes for an interesting problem
|
|
|
|
as parts of GCC can only be built with GCC.
|
|
|
|
|
|
|
|
To build a cross compiler, we first recommend building and installing a
|
|
|
|
native compiler. You can then use the native GCC compiler to build the
|
|
|
|
cross compiler.
|
|
|
|
|
|
|
|
Assuming you have already installed a native copy of GCC and configured
|
2001-06-13 15:07:28 +02:00
|
|
|
your cross compiler, issue the command @command{make}, which performs the
|
2001-05-12 00:10:54 +02:00
|
|
|
following steps:
|
|
|
|
|
|
|
|
@itemize @bullet
|
|
|
|
@item
|
|
|
|
Build host tools necessary to build the compiler such as texinfo, bison,
|
|
|
|
gperf.
|
|
|
|
|
|
|
|
@item
|
|
|
|
Build target tools for use by the compiler such as binutils (bfd,
|
|
|
|
binutils, gas, gprof, ld, and opcodes)
|
|
|
|
if they have been individually linked or moved into the top level GCC source
|
|
|
|
tree before configuring.
|
|
|
|
|
|
|
|
@item
|
|
|
|
Build the compiler (single stage only).
|
|
|
|
|
|
|
|
@item
|
|
|
|
Build runtime libraries using the compiler from the previous step.
|
|
|
|
@end itemize
|
|
|
|
|
|
|
|
Note that if an error occurs in any step the make process will exit.
|
|

|
|
@section Building in parallel
|
|
|
|
|
2001-06-01 20:08:19 +02:00
|
|
|
If you have a multiprocessor system you can use @samp{make bootstrap
|
|
|
|
MAKE="make -j 2" -j 2} or just @samp{make -j 2 bootstrap}
|
|
|
|
for GNU Make 3.79 and above instead of just @samp{make bootstrap}
|
2001-05-12 00:10:54 +02:00
|
|
|
when building GCC. You can use a bigger number instead of two if
|
|
|
|
you like. In most cases, it won't help to use a number bigger than
|
|
|
|
the number of processors in your machine.

@strong{Please note that this is only applicable
|

to current development versions of GCC and GCC 3.0 or later.
|
|
|
|
GCC 2.95.x does not come with a testsuite.}
|
|
|
|
|
|
|
|
Before you install GCC, you might wish to run the testsuite. This
|
|
|
|
step is optional and may require you to download additional software.
|
|
|
|
|
|
|
|
First, you must have @uref{download.html,,downloaded the testsuites}.
|
|
|
|
The full distribution contains testsuites; only if you downloaded the
|
|
|
|
``core'' compiler plus any front ends, you do not have the testsuites.
|
|
|
|
|
|
|
|
Second, you must have a @uref{http://www.gnu.org/software/dejagnu/,,current version of DejaGnu} installed;
|
|
|
|
dejagnu 1.3 is not sufficient.
|
|
|
|
|
|
|
|
Now you may need specific preparations:
|
|
|
|
|
|
|
|

In order to run the libio tests in GCC 2.95 and earlier versions of GCC
|
|
|
|
on targets which do not fully
|
2001-06-13 15:07:28 +02:00
|
|
|
support Unix/POSIX commands (e.g. Cygwin), the references to the @file{dbz}
|
|
|
|
directory have to be deleted from @file{libio/configure.in}.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
@item
|
2001-06-11 09:26:33 +02:00
|
|
|
The following environment variables may need to be set appropriately, as in
|
2001-05-12 00:10:54 +02:00
|
|
|
the following example (which assumes that DejaGnu has been installed
|
2001-06-13 15:07:28 +02:00
|
|
|
under @file{/usr/local}):
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
@example
|
|
|
|
TCL_LIBRARY = /usr/local/share/tcl8.0
|
|
|
|
DEJAGNULIBS = /usr/local/share/dejagnu
|
|
|
|
@end example
|
|
|
|
|
|
|
|
On systems such as Cygwin, these paths are required to be actual
|
|
|
|
paths, not mounts or links; presumably this is due to some lack of
|
|
|
|
portability in the DejaGnu code.
|
|
|
|
|
2001-06-11 09:26:33 +02:00
|
|
|
If the directories where @command{runtest} and @command{expect} were
|
|
|
|
installed are in the @env{PATH}, it should not be necessary to set these
|
|
|
|
environment variables.
|
|
|
|
|
2001-05-12 00:10:54 +02:00
|
|
|
@end itemize
|
|
|
|
|
|
|
|
Finally, you can run the testsuite (which may take a long time):
|
|
|
|
@example
|
2001-06-02 20:21:37 +02:00
|
|
|
cd @var{objdir}; make -k check
|
2001-05-12 00:10:54 +02:00
|
|
|
@end example
|
|
|
|
|
|
|
|
The testing process will try to test as many components in the GCC
|
2001-06-21 17:25:56 +02:00
|
|
|
distribution as possible, including the C, C++, Objective-C and Fortran
|
2001-06-11 09:26:33 +02:00
|
|
|
compilers as well as the C++ and Java runtime libraries.

|
|
|
|
@section How can I run the test suite on selected tests?
|
|
|
|
|
|
|
|
As a first possibility to cut down the number of tests that are run it is
|
2001-06-01 20:08:19 +02:00
|
|
|
possible to use @samp{make check-gcc} or @samp{make check-g++}
|
2001-05-12 00:10:54 +02:00
|
|
|
in the gcc subdirectory of the object directory. To further cut down the
|
|
|
|
tests the following is possible:
|
|
|
|
|
|
|
|
@example
|
2001-06-13 15:07:28 +02:00
|
|
|
make check-gcc RUNTESTFLAGS="execute.exp @var{other-options}"
|
2001-05-12 00:10:54 +02:00
|
|
|
@end example
|
|
|
|
|
|
|
|
This will run all gcc execute tests in the testsuite.
|
|
|
|
|
|
|
|
@example
|
2001-06-13 15:07:28 +02:00
|
|
|
make check-g++ RUNTESTFLAGS="old-deja.exp=9805* @var{other-options}"
|
2001-05-12 00:10:54 +02:00
|
|
|
@end example
|
|
|
|
|
2001-06-13 15:07:28 +02:00
|
|
|
This will run the g++ ``old-deja'' tests in the testsuite where the filename
|
|
|
|
matches @samp{9805*}.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
2001-06-13 15:07:28 +02:00
|
|
|
The @file{*.exp} files are located in the testsuite directories of the GCC
|
|
|
|
source, the most important ones being @file{compile.exp},
|
|
|
|
@file{execute.exp}, @file{dg.exp} and @file{old-deja.exp}.
|
|
|
|
To get a list of the possible @file{*.exp} files, pipe the
|
2001-06-01 20:08:19 +02:00
|
|
|
output of @samp{make check} into a file and look at the
|
2001-06-13 15:07:28 +02:00
|
|
|
@samp{Running @dots{} .exp} lines.

@section How to interpret test results
|
|
|
|
|
2001-06-13 15:07:28 +02:00
|
|
|
After the testsuite has run you'll find various @file{*.sum} and @file{*.log}
|
|
|
|
files in the testsuite subdirectories. The @file{*.log} files contain a
|
2001-05-12 00:10:54 +02:00
|
|
|
detailed log of the compiler invocations and the corresponding
|
2001-06-13 15:07:28 +02:00
|
|
|
results, the @file{*.sum} files summarize the results. These summaries list
|
2001-05-12 00:10:54 +02:00
|
|
|
all the tests that have been run with a corresponding status code:

make sure it is in your @env{PATH}. The file @file{your_commentary.txt} is

remarks you have on your results or your build environment. Please
|
|
|
|
do not edit the testsuite result block or the subject line, as these

|
messages are automatically parsed and presented at the
|
|
|
|
@uref{http://gcc.gnu.org/testresults/,,GCC testresults} web
|
|

behave on different platforms and compare them with your results. A

few failing testcases are possible even on released versions and you
|

Now that GCC has been built and tested, you can install it with
|
2001-06-11 03:03:12 +02:00
|
|
|
@samp{cd @var{objdir}; make install}.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
That step completes the installation of GCC; user level binaries can
|
2001-06-01 20:08:19 +02:00
|
|
|
be found in @file{@var{prefix}/bin} where @var{prefix} is the value you
|
|
|
|
specified with the @option{--prefix} to configure (or @file{/usr/local}
|
2001-06-12 21:36:53 +02:00
|
|
|
by default). (If you specified @option{--bindir}, that directory will
|
|
|
|
be used instead; otherwise, if you specified @option{--exec-prefix},
|
|
|
|
@file{@var{exec-prefix}/bin} will be used.) Headers for the C++ and
|
|
|
|
Java libraries are installed in @file{@var{prefix}/include}; libraries
|
|
|
|
in @file{@var{libdir}} (normally @file{@var{prefix}/lib}); internal
|
|

If you want to print the GCC manuals, do @samp{cd @var{objdir}; make
|
|
|
|
dvi}. You will need to have @command{texi2dvi} (version at least 4.0)
|
|
|
|
and @TeX{} installed. This creates a number of @file{.dvi} files in
|
|
|
|
subdirectories of @file{@var{objdir}}; these may be converted for
|
|
|
|
printing with programs such as @command{dvips}. You can also
|
|
|
|
@uref{http://www.gnu.org/order/order.html,,buy printed manuals from the
|
|
|
|
Free Software Foundation}, though such manuals may not be for the most
|
|
|
|
recent version of GCC.

We are often asked about pre-compiled versions of GCC. While we cannot
|
|
|
|
provide these for all platforms, below you'll find links to binaries for
|
|
|
|
various platforms where creating them by yourself is not easy due to various
|
|
|
|
reasons.
|
|
|
|
|
|
|
|
Please note that we did not create these binaries, nor do we
|
|
|
|
support them. If you have any problems installing them, please
|
|
|
|
contact their makers.

In addition to those specific offerings, you can get a binary
|
|
|
|
distribution CD-ROM from the
|
|
|
|
@uref{http://www.fsf.org/order/order.html,,Free Software Foundation}.
|
|
|
|
It contains binaries for a number of platforms, and
|
|
|
|
includes not only GCC, but other stuff as well. The current CD does
|
|
|
|
not contain the latest version of GCC, but it should allow
|
|
|
|
bootstrapping the compiler. An updated version of that disk is in the
|
|
|
|
works.

We require binutils 2.11.1 (as of yet unreleased), binutils with
|
2001-06-13 15:07:28 +02:00
|
|
|
@samp{binutils-2_11-branch} tag after May 31, 2001 (as taken below), or newer.
|
2001-06-05 00:56:53 +02:00
|
|
|
Previous binutils releases had a number of problems with DWARF2
|
|
|
|
debugging information, not the least of which is incorrect linking of
|
|
|
|
shared libraries.
|
|
|
|

Until binutils 2.11.1 is released, these sample commands may be useful:
|

|
|
|
|
|
@smallexample
|
|
|
|
mkdir binutils-2.11.X; cd binutils-2.11.X

Systems using processors that implement the DEC Alpha architecture and
|
2001-06-15 19:35:48 +02:00
|
|
|
are running the DEC/Compaq Unix (DEC OSF/1, Digital UNIX, or Compaq
|
|
|
|
Tru64 UNIX) operating system, for example the DEC Alpha AXP systems.
|
|
|
|
|
|
|
|
In Tru64 UNIX V5.1, Compaq introduced a new assembler that does not
|
|
|
|
currently (2001-06-13) work with @command{mips-tfile}. As a workaround,
|
|
|
|
we need to use the old assembler, invoked via the barely documented
|
|
|
|
@option{-oldas} option. To bootstrap GCC, you either need to use the
|
|
|
|
Compaq C Compiler:
|
|
|
|
|
|
|
|
@example
|
|
|
|
% CC=cc @var{srcdir}/configure [@var{target}] [@var{options}]
|
|
|
|
@end example
|
|
|
|
|
|
|
|
or you can use a copy of GCC 2.95.3 or higher built on Tru64 UNIX V4.0:
|
|
|
|
|
|
|
|
@example
|
|
|
|
% CC=gcc -Wa,-oldas @var{srcdir}/configure [@var{target}] [@var{options}]
|
|
|
|
@end example
|
2001-06-03 00:33:30 +02:00
|
|
|
|
|
|
|
GNU CC writes a @samp{.verstamp} directive to the assembler output file
|
|
|
|
unless it is built as a cross-compiler. It gets the version to use from
|
|
|
|
the system header file @file{/usr/include/stamp.h}. If you install a
|
|
|
|
new version of DEC Unix, you should rebuild GCC to pick up the new version
|
|
|
|
stamp.
|
|
|
|
|
|
|
|
Note that since the Alpha is a 64-bit architecture, cross-compilers from
|
|
|
|
32-bit machines will not generate code as efficient as that generated
|
|
|
|
when the compiler is running on a 64-bit machine because many
|
|
|
|
optimizations that depend on being able to represent a word on the
|
|
|
|
target in an integral value on the host cannot be performed. Building
|
|
|
|
cross-compilers on the Alpha for 32-bit machines has only been tested in
|
|
|
|
a few cases and may not work properly.
|
|
|
|
|
|
|
|
@code{make compare} may fail on old versions of DEC Unix unless you add
|
2001-06-13 15:07:28 +02:00
|
|
|
@option{-save-temps} to @code{CFLAGS}. On these systems, the name of the
|
2001-06-03 00:33:30 +02:00
|
|
|
assembler input file is stored in the object file, and that makes
|
|
|
|
comparison fail if it differs between the @code{stage1} and
|
2001-06-13 15:07:28 +02:00
|
|
|
@code{stage2} compilations. The option @option{-save-temps} forces a
|
2001-06-03 00:33:30 +02:00
|
|
|
fixed name to be used for the assembler input file, instead of a
|
2001-06-13 15:07:28 +02:00
|
|
|
randomly chosen name in @file{/tmp}. Do not add @option{-save-temps}
|
2001-06-03 00:33:30 +02:00
|
|
|
unless the comparisons fail without that option. If you add
|
2001-06-13 15:07:28 +02:00
|
|
|
@option{-save-temps}, you will have to manually delete the @samp{.i} and
|
2001-06-03 00:33:30 +02:00
|
|
|
@samp{.s} files after each series of compilations.
|
|
|
|
|
|
|
|
GNU CC now supports both the native (ECOFF) debugging format used by DBX
|
|
|
|
and GDB and an encapsulated STABS format for use only with GDB. See the
|
2001-06-13 15:07:28 +02:00
|
|
|
discussion of the @option{--with-stabs} option of @file{configure} above
|
2001-06-03 00:33:30 +02:00
|
|
|
for more information on these formats and how to select them.
|
|
|
|
|
|
|
|
There is a bug in DEC's assembler that produces incorrect line numbers
|
|
|
|
for ECOFF format when the @samp{.align} directive is used. To work
|
|
|
|
around this problem, GNU CC will not emit such alignment directives
|
|
|
|
while writing ECOFF format debugging information even if optimization is
|
|
|
|
being performed. Unfortunately, this has the very undesirable
|
2001-06-13 15:07:28 +02:00
|
|
|
side-effect that code addresses when @option{-O} is specified are
|
|
|
|
different depending on whether or not @option{-g} is also specified.
|
2001-06-03 00:33:30 +02:00
|
|
|
|
2001-06-13 15:07:28 +02:00
|
|
|
To avoid this behavior, specify @option{-gstabs+} and use GDB instead of
|
2001-06-03 00:33:30 +02:00
|
|
|
DBX. DEC is now aware of this problem with the assembler and hopes to
|
|
|
|
provide a fix shortly.

Specifically, @option{-g} does not work on HP-UX (since that system

uses a peculiar debugging format which GCC does not know about), unless you
|
2001-06-01 20:08:19 +02:00
|
|
|
use GAS and GDB and configure GCC with the
|
|
|

2001-06-13 15:07:28 +02:00

The HP assembler has major problems on this platform. We've tried to work
|
|
|
|
around the worst of the problems. However, those workarounds may be causing
|
|
|
|
linker crashes in some circumstances; the workarounds also probably prevent
|
|
|
|
shared libraries from working. Use the GNU assembler to avoid these problems.
|
|
|
|
|
|
|
|
|
|
|
|
The configuration scripts for GCC will also trigger a bug in the hpux9
|
2001-06-01 20:08:19 +02:00
|

shell. To avoid this problem set @env{CONFIG_SHELL} to @file{/bin/ksh}

and @env{SHELL} to @file{/bin/ksh} in your environment.

The HP assembler on these systems is much better than the hpux9 assembler,
|
|
|
|
but still has some problems. Most notably the assembler inserts timestamps
|
|
|
|
into each object file it creates, causing the 3-stage comparison test to fail
|
2001-06-01 20:08:19 +02:00
|
|
|
during a @samp{make bootstrap}. You should be able to continue by
|
|
|
|
saying @samp{make all} after getting the failure from @samp{make
|
|
|
|
bootstrap}.

The version of binutils installed in @file{/usr/bin} is known to work unless

2001-06-05 00:56:53 +02:00
|
|

otherwise specified in any per-architecture notes. However, binutils
|

2.11 is known to improve overall testsuite results.

For FreeBSD 1, FreeBSD 2 or any mutant a.out versions of FreeBSD 3: All

place. FreeBSD 2.2.7 has been known to bootstrap completely; however,

it is unknown which version of binutils was used (it is assumed that it

For FreeBSD using the ELF file format: DWARF2 debugging is now the

default for all CPU architectures. It had been the default on
|
|
|
|
FreeBSD/alpha since its inception. You may use @option{-gstabs} instead
|
|
|
|
of @option{-g}, if you really want the old debugging format. There are
|
|
|
|
no known issues with mixing object files and libraries with different
|
|
|
|
debugging formats. Otherwise, this release of gcc should now match more
|
|
|
|
of the configuration used in the stock FreeBSD configuration of gcc. In
|
|
|
|
particular, @option{--enable-threads} is now configured by default.
|
|
|

However, as a general user, do not attempt to replace the system

compiler with this release. Known to bootstrap and check with good

results on FreeBSD 3.0, 3.4, 4.0, 4.2, 4.3 and 5-CURRENT.
|
|
|
|
|
|

At this time, @option{--enable-threads} is not compatible with
|
|
|
|
@option{--enable-libgcj} on FreeBSD.

Currently Glibc 2.2.3 (and older releases) and GCC 3.0 are out of sync
|
|
|
|
since the latest exception handling changes for GCC. Compiling glibc
|
|
|
|
with GCC 3.0 will give a binary incompatible glibc and therefore cause
|
|
|
|
lots of problems and might make your system completly unusable. This
|
|
|
|
will definitly need fixes in glibc but might also need fixes in GCC. We
|
|
|
|
strongly advise to wait for glibc 2.2.4 and to read the release notes of
|
|
|
|
glibc 2.2.4 whether patches for GCC 3.0 are needed. You can use glibc
|
|
|
|
2.2.3 with GCC 3.0, just do not try to recompile it.

link with GNU malloc instead of the malloc that comes with the system.

Unlike earlier versions of GCC, the ability to generate COFF with this
|
|
|
|
target is no longer provided.
|
|
|
|
|
|
|
|
Earlier versions of GCC emitted Dwarf-1 when generating ELF to allow
|
|
|
|
the system debugger to be used. That support was too burdensome to
|
|
|
|
maintain. GCC now emits only dwarf-2 for this target. This means you
|
|
|
|
may use either the UDK debugger or GDB to debug programs built by this
|
|
|
|
version of GCC.
|
|
|
|
|
|
|
|
If you are building languages other than C, you must follow the instructions
|
2001-06-01 20:08:19 +02:00
|
|
|
about invoking @samp{make bootstrap} because the native OpenServer
|
|
|
|
compiler will build a @command{cc1plus} that will not correctly parse many
|
|
|
|
valid C++ programs including those in @file{libgcc.a}.
|
|
|
|
@strong{You must do a @samp{make bootstrap} if you are building with the
|
2001-05-12 00:10:54 +02:00
|

native compiler.}

Use of the @option{-march-pentiumpro} flag can result in
|
2001-05-12 00:10:54 +02:00
|
|
|
unrecognized opcodes when using the native assembler on OS versions before
|
|
|
|
5.0.6. (Support for P6 opcodes was added to the native ELF assembler in
|
|
|
|
that version.) While it's rather rare to see these emitted by GCC yet,
|
|
|
|
errors of the basic form:
|
|
|
|
|
|
|
|
@example
|
|
|
|
/usr/tmp/ccaNlqBc.s:22:unknown instruction: fcomip
|
|
|
|
/usr/tmp/ccaNlqBc.s:50:unknown instruction: fucomip
|
|
|
|
@end example
|
|
|
|
|
|
|
|
are symptoms of this problem. You may work around this by not
|
|
|
|
building affected files with that flag, by using the GNU assembler, or
|
|
|
|
by using the assembler provided with the current version of the OS.
|
|
|
|
Users of GNU assembler should see the note below for hazards on doing
|
|
|
|
so.
|
|
|
|
|
|
|
|
The native SCO assembler that is provided with the OS at no
|
|
|
|
charge is normally required. If, however, you must be able to use
|
|
|
|
the GNU assembler (perhaps you're compiling code with asms that
|
|
|
|
require GAS syntax) you may configure this package using the flags
|
2001-06-01 20:08:19 +02:00
|
|
|
@uref{./configure.html#with-gnu-as,,@option{--with-gnu-as}}. You must
|
|
|
|
use a recent version of GNU binutils; versions past 2.9.1 seem to work
|
|
|
|
well.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
In general, the @option{--with-gnu-as} option isn't as well tested
|
|
|
|
as the native assembler.

|
The system linker in (at least) 5.0.4 and 5.0.5 will sometimes
|
|
|
|
do the wrong thing for a construct that GCC will emit for PIC
|
|
|
|
code. This can be seen as execution testsuite failures when using
|
2001-06-13 15:07:28 +02:00
|
|
|
@option{-fPIC} on @file{921215-1.c}, @file{931002-1.c}, @file{nestfunc-1.c}, and @file{gcov-1.c}.
|
2001-05-12 00:10:54 +02:00

|
For 5.0.5, an updated linker that will cure this problem is
|
|

available. You must install both

|
|
|
|
|
|
|
|
The dynamic linker in OpenServer 5.0.5 (earlier versions may show
|
|
|
|
the same problem) aborts on certain g77-compiled programs. It's particularly
|
|
|
|
likely to be triggered by building Fortran code with the @option{-fPIC} flag.
|
|
|
|
Although it's conceivable that the error could be triggered by other
|
|
|
|
code, only G77-compiled code has been observed to cause this abort.
|
|
|
|
If you are getting core dumps immediately upon execution of your
|

|
|
|
g77 program---and especially if it's compiled with @option{-fPIC}---try applying

This target emulates the SCO Universal Development Kit and requires that
|
|
|
|
package be installed. (If it is installed, you will have a
|
2001-06-13 15:07:28 +02:00
|
|
|
@file{/udk/usr/ccs/bin/cc} file present.) It's very much like the
|
2001-05-12 00:10:54 +02:00
|
|
|
@code{i?86-*-unixware7*} target
|
|
|
|
but is meant to be used when hosting on a system where UDK isn't the
|
|
|
|
default compiler such as OpenServer 5 or Unixware 2. This target will
|
|
|
|
generate binaries that will run on OpenServer, Unixware 2, or Unixware 7,
|
|
|
|
with the same warnings and caveats as the SCO UDK.
|
|
|
|
|
|
|
|
You can stage1 with either your native compiler or with UDK. If you
|
|
|
|
don't do a full bootstrap when initially building with your native compiler
|
|
|
|
you will have an utterly unusable pile of bits as your reward.
|
|
|
|
|
|
|
|
This target is a little tricky to build because we have to distinguish
|
|
|
|
it from the native tools (so it gets headers, startups, and libraries
|
|
|
|
from the right place) while making the tools not think we're actually
|
|
|
|
building a cross compiler. The easiest way to do this is with a configure
|
|
|
|
command like this:
|
|
|
|
|
2001-06-13 15:07:28 +02:00
|
|
|
@samp{CC=/udk/usr/ccs/bin/cc @var{/your/path/to}/gcc/configure
|
2001-05-12 00:10:54 +02:00
|
|
|
--host=i686-pc-udk --target=i686-pc-udk --program-prefix=udk-}
|
|
|
|
|
2001-06-13 15:07:28 +02:00
|
|
|
@emph{You should substitute @samp{i686} in the above command with the appropriate
|
2001-05-12 00:10:54 +02:00
|
|
|
processor for your host.}
|
|
|
|
|
2001-06-01 20:08:19 +02:00
|
|
|
You should follow this with a @samp{make bootstrap} then
|
|
|
|
@samp{make install}. You can then access the UDK-targeted GCC
|
|
|
|
tools by adding @command{udk-} before the commonly known name. For
|
|
|
|
example, to invoke the C compiler, you would use @command{udk-gcc}.
|
|
|
|
They will coexist peacefully with any native-target GCC tools you may
|
|
|
|
have installed.

AIX Make frequently has problems with GCC makefiles. GNU Make 3.76 or

newer is recommended to build on this platform.

Errors involving @code{alloca} when building GCC generally are due
|
2001-06-01 20:08:19 +02:00
|
|
|
to an incorrect definition of @var{CC} in the Makefile or mixing files
|
2001-05-12 00:10:54 +02:00
|
|
|
compiled with the native C compiler and GCC. During the stage1 phase of
|
2001-06-13 15:07:28 +02:00
|
|
|
the build, the native AIX compiler @strong{must} be invoked as @command{cc}
|
|
|
|
(not @command{xlc}). Once @command{configure} has been informed of
|
|
|
|
@command{xlc}, one needs to use @samp{make distclean} to remove the
|
2001-06-01 20:08:19 +02:00
|
|
|
configure cache files and ensure that @env{CC} environment variable
|
2001-05-12 00:10:54 +02:00
|
|
|
does not provide a definition that will confuse @command{configure}.
|
|
|
|
If this error occurs during stage2 or later, then the problem most likely
|
|
|
|
is the version of Make (see above).

|
|

website does work. Binutils 2.11 is expected to include AIX 4.3
|
|
|

support. The GNU Assembler is necessary for libstdc++ to build. The

AIX native ld still is recommended. The native AIX tools do
|
|
|
|
interoperate with GCC.
|
|
|
|
|
|
|
|
Linking executables and shared libraries may produce warnings of
|
|
|
|
duplicate symbols. The assembly files generated by GCC for AIX always
|
|
|
|
have included multiple symbol definitions for certain global variable
|
|
|
|
and function declarations in the original program. The warnings should
|
|
|
|
not prevent the linker from producing a correct library or runnable
|

executable.

AIX 4.3 utilizes a ``large format'' archive to support both 32-bit and

2001-05-16 16:57:06 +02:00
|
|

64-bit object modules. The routines provided in AIX 4.3.0 and AIX 4.3.1
|
|
|
|
to parse archive libraries did not handle the new format correctly.
|
|
|
|
These routines are used by GCC and result in error messages during
|
2001-06-13 15:07:28 +02:00
|
|

Use @samp{configure unos} for building on Unos.
|
|
|
|
|
|
|
|
The Unos assembler is named @code{casm} instead of @code{as}. For some
|
|
|
|
strange reason linking @file{/bin/as} to @file{/bin/casm} changes the
|
|
|
|
behavior, and does not work. So, when installing GNU CC, you should
|
|
|
|
install the following script as @file{as} in the subdirectory where
|
|
|
|
the passes of GCC are installed:
|
|
|
|
|
|
|
|
@example
|
|
|
|
#!/bin/sh
|
|
|
|
casm $*
|
|
|
|
@end example
|
|
|
|
|
|
|
|
The default Unos library is named @file{libunos.a} instead of
|
|
|
|
@file{libc.a}. To allow GNU CC to function, either change all
|
2001-06-13 15:07:28 +02:00
|
|
|
references to @option{-lc} in @file{gcc.c} to @option{-lunos} or link
|
2001-06-03 00:33:30 +02:00
|
|
|
@file{/lib/libc.a} to @file{/lib/libunos.a}.
|
|
|
|
|
|
|
|
@cindex @code{alloca}, for Unos
|
|
|
|
When compiling GNU CC with the standard compiler, to overcome bugs in
|
2001-06-13 15:07:28 +02:00
|
|
|
the support of @code{alloca}, do not use @option{-O} when making stage 2.
|
|
|
|
Then use the stage 2 compiler with @option{-O} to make the stage 3
|
2001-06-03 00:33:30 +02:00
|
|
|
compiler. This compiler will have the same characteristics as the usual
|
|
|
|
stage 2 compiler on other systems. Use it to make a stage 4 compiler
|
|
|
|
and compare that with stage 3 to verify proper compilation.
|
|
|
|
|
|
|
|
(Perhaps simply defining @code{ALLOCA} in @file{x-crds} as described in
|
|
|
|
the comments there will make the above paragraph superfluous. Please
|
|
|
|
inform us of whether this works.)
|
|
|
|
|
|
|
|
Unos uses memory segmentation instead of demand paging, so you will need
|
|
|
|
a lot of memory. 5 Mb is barely enough if no other tasks are running.
|
|
|
|
If linking @file{cc1} fails, try putting the object files into a library
|
|
|
|
and linking from that library.

HP, as described in the following note:

This is the patched assembler, to patch SR#1653-010439, where the
|
|
|
|
assembler aborts on floating point constants.
|
|
|
|
|
|
|
|
The bug is not really in the assembler, but in the shared library
|
|
|
|
version of the function ``cvtnum(3c)''. The bug on ``cvtnum(3c)'' is
|
|
|
|
SR#4701-078451. Anyway, the attached assembler uses the archive
|
|
|
|
library version of ``cvtnum(3c)'' and thus does not exhibit the bug.

|
|
|

In addition, if you wish to use gas @option{--with-gnu-as} you must use
|
2001-06-03 00:33:30 +02:00
|
|
|
gas version 2.1 or later, and you must use the GNU linker version 2.1 or
|
|
|
|
later. Earlier versions of gas relied upon a program which converted the
|
|
|
|
gas output into the native HP-UX format, but that program has not been
|
|
|
|
kept up to date. gdb does not understand that native HP-UX format, so
|
|
|
|
you must use gas if you wish to use gdb.
|
|
|
|
|
|
|
|
On HP-UX version 8.05, but not on 8.07 or more recent versions, the
|
|
|
|
@code{fixproto} shell script triggers a bug in the system shell. If you
|
|
|
|
encounter this problem, upgrade your operating system or use BASH (the
|
|
|
|
GNU shell) to run @code{fixproto}. This bug will cause the fixproto
|
|
|
|
program to report an error of the form:
|
|
|
|
|
|
|
|
@example
|
|
|
|
./fixproto: sh internal 1K buffer overflow
|
|
|
|
@end example
|
|
|
|
|
|
|
|
To fix this, you can also change the first line of the fixproto script
|
|
|
|
to look like:
|
|
|
|
|
|
|
|
@example
|

On NeXTStep 3.0, the Objective-C compiler does not work, due,
|
2001-06-03 00:33:30 +02:00

apparently, to a kernel bug that it happens to trigger. This problem
|

does not happen on 3.1.

|
@example
|
|
|
|
_eh
|
|

/usr/tmp/ccbbsZ0U.s:987:Unknown pseudo-op: .section
|
|
|

/usr/tmp/ccbbsZ0U.s:987:Rest of line ignored. 1st junk character
|
|
|
|
valued 95 (_).
|
|
|
|
@end example
|
|
|
|
|
|
|
|
The reason for this is the fact that NeXT's assembler for these
|
2001-06-13 15:07:28 +02:00
|
|
|
versions of the operating system does not support the @samp{.section}
|
2001-05-12 00:10:54 +02:00
|
|
|
pseudo op that's needed for full C++ exception functionality.
|
|
|
|
|
|
|

As NeXT's assembler is a derived work from GNU as, a free
|
|
|

replacement that does can be obtained at

If you try to build the integrated C++ & C++ runtime libraries on this system

the directory @var{prefix} you specified in the configuration process of GCC

for this sequence to work.

Motorola m88k running the AT&T/Unisoft/Motorola V.3 reference port.

These systems tend to use the Green Hills C, revision 1.8.5, as the
|
|
|
|
standard C compiler. There are apparently bugs in this compiler that
|
|
|
|
result in object files differences between stage 2 and stage 3. If this
|
|
|
|
happens, make the stage 4 compiler and compare it to the stage 3
|
|
|
|
compiler. If the stage 3 and stage 4 object files are identical, this
|
|
|
|
suggests you encountered a problem with the standard C compiler; the
|
|
|
|
stage 3 and 4 compilers may be usable.
|
|
|
|
|
|

|
It is best, however, to use an older version of GNU CC for bootstrapping

if you have one.

If you use the 1.31 version of the MIPS assembler (such as was shipped
|
2001-06-13 15:07:28 +02:00
|
|
|
with Ultrix 3.1), you will need to use the @option{-fno-delayed-branch} switch
|
2001-06-03 00:33:30 +02:00
|
|
|
when optimizing floating point code. Otherwise, the assembler will
|
|
|
|
complain when the GCC compiler fills a branch delay slot with a
|
|
|
|
floating point instruction, such as @code{add.d}.
|

If on a MIPS system you get an error message saying ``does not have gp
|
|
|
|
sections for all it's [sic] sectons [sic]'', don't worry about it. This
|
|
|
|
happens whenever you use GAS with the MIPS linker, but there is not
|
|
|
|
really anything wrong, and it is okay to use the output file. You can
|
|
|
|
stop such warnings by installing the GNU linker.
|
|
|
|
|
|
|
|
It would be nice to extend GAS to produce the gp tables, but they are
|
|
|
|
optional, and there should not be a warning about their absence.
|
|
|
|
|
|
|
|
Users have reported some problems with version 2.0 of the MIPS
|
|
|
|
compiler tools that were shipped with Ultrix 4.1. Version 2.10
|
|
|
|
which came with Ultrix 4.2 seems to work fine.
|
|
|
|
|
|
|
|
Users have also reported some problems with version 2.20 of the
|
|
|
|
MIPS compiler tools that were shipped with RISC/os 4.x. The earlier
|
|
|
|
version 2.11 seems to work fine.

Some versions of the MIPS linker will issue an assertion failure
|
|
|
|
when linking code that uses @code{alloca} against shared
|
|
|
|
libraries on RISC-OS 5.0, and DEC's OSF/1 systems. This is a bug
|
|
|
|
in the linker, that is supposed to be fixed in future revisions.
|
2001-06-13 15:07:28 +02:00
|
|
|
To protect against this, GCC passes @option{-non_shared} to the
|
|
|
|
linker unless you pass an explicit @option{-shared} or
|
|
|
|
@option{-call_shared} switch.

2001-06-13 15:07:28 +02:00
|

@code{stage2} compilations. The option @option{-save-temps} forces a
|
2001-06-03 00:33:30 +02:00

fixed name to be used for the assembler input file, instead of a

On Irix version 4.0.5F, and perhaps on some other versions as well,
|
|
|
|
there is an assembler bug that reorders instructions incorrectly. To
|
|
|
|
work around it, specify the target configuration
|
|
|
|
@samp{mips-sgi-irix4loser}. This configuration inhibits assembler
|
|
|
|
optimization.
|
|
|
|
|
|
|
|
In a compiler configured with target @samp{mips-sgi-irix4}, you can turn
|
2001-06-13 15:07:28 +02:00
|
|
|
off assembler optimization by using the @option{-noasmopt} option. This
|
|
|
|
compiler option passes the option @option{-O0} to the assembler, to
|
2001-06-03 00:33:30 +02:00
|
|
|
inhibit reordering.
|
|
|
|
|
2001-06-13 15:07:28 +02:00
|
|
|
The @option{-noasmopt} option can be useful for testing whether a problem
|
2001-06-03 00:33:30 +02:00
|
|
|
is due to erroneous assembler reordering. Even if a problem does not go
|
2001-06-13 15:07:28 +02:00
|
|
|
away with @option{-noasmopt}, it may still be due to assembler
|
2001-06-03 00:33:30 +02:00
|
|
|
reordering---perhaps GNU CC itself was miscompiled as a result.

To enable debugging under Irix 5, you must use GNU as 2.5 or later,

You must use GAS on these platforms, as the native assembler can not handle
|
|
|
|
the code for exception handling support. Either of these messages indicates
|
|
|
|
that you are using the MIPS assembler when instead you should be using GAS:

@end example
|
|
|

|
|
|
|
then your version of @command{cc} uses the O32 ABI default. You
|
2001-06-01 20:08:19 +02:00
|
|
|
should set the environment variable @env{CC} to @samp{cc -n32}
|
2001-05-12 00:10:54 +02:00
|
|
|
before configuring GCC.
|
|
|
|
|
|
|
|
GCC does not currently support generating O32 ABI binaries in the
|
|
|
|
mips-sgi-irix6 configurations. It used to be possible to create a GCC
|
|
|
|
with O32 ABI only support by configuring it for the mips-sgi-irix5
|
|
|
|
target. See the link below for details.
|
|
|
|
|
|
|
|
GCC does not correctly pass/return structures which are
|
|
|
|
smaller than 16 bytes and which are not 8 bytes. The problem is very
|
|
|
|
involved and difficult to fix. It affects a number of other targets also,
|
|
|
|
but IRIX 6 is affected the most, because it is a 64 bit target, and 4 byte
|
|
|
|
structures are common. The exact problem is that structures are being padded
|
|
|
|
at the wrong end, e.g. a 4 byte structure is loaded into the lower 4 bytes
|
|
|
|
of the register when it should be loaded into the upper 4 bytes of the
|
|
|
|
register.
|
|
|
|
|
|
|
|
GCC is consistent with itself, but not consistent with the SGI C compiler
|
|
|
|
(and the SGI supplied runtime libraries), so the only failures that can
|
|
|
|
happen are when there are library functions that take/return such
|
|
|
|
structures. There are very few such library functions. I can only recall
|
|
|
|
seeing two of them: inet_ntoa, and semctl.

The only operating systems supported for the IBM RT PC are AOS and

|
|
MACH. GNU CC does not support AIX running on the RT. We recommend you
|
|
|
|
compile GNU CC with an earlier version of itself; if you compile GNU CC
|
|
|
|
with @code{hc}, the Metaware compiler, it will work, but you will get
|
|
|
|
mismatches between the stage 2 and stage 3 compilers in various files.
|
|
|
|
These errors are minor differences in some floating-point constants and
|
|
|
|
can be safely ignored; the stage 3 compiler is correct.

Starting with Solaris, Sun does not ship a C compiler any more. To
|
|
|
|
bootstrap and install GCC you first have to install a pre-built
|
|
|
|
compiler, see our @uref{binaries.html,,binaries page} for
|
|
|
|
details.
|
|
|
|
|

You must use GNU Make to build GCC on Solaris 2. If you don't have GNU
|
|
|

Make installed, you can use the prebuilt compiler mentioned above to

|

build it.

Sun as 4.X is broken in that it cannot cope with long symbol names.
|
|
|
|
A typical error message might look similar to the following:
|
|
|
|
|
|
|
|
@samp{/usr/ccs/bin/as: "/var/tmp/ccMsw135.s", line 11041:
|
|

error: can't compute value of an expression involving an external symbol.}
|
|
|
|
|
2001-05-17 20:12:27 +02:00
|
|
|
This is Sun bug 4237974. This is fixed with patch 108908-02 and has
|
|
|
|
been fixed in later (5.x) versions of the assembler.

|
libjava. If you encounter this problem, set @var{CONFIG_SHELL} to
|

|

|
@file{/bin/ksh} in your environment and run @samp{make bootstrap} again.

On Solaris 2, executables of GCC version 2.0.2 are commonly
|
|
|
|
available, but they have a bug that shows up when compiling current
|
|
|
|
versions of GCC: undefined symbol errors occur during assembly if you
|
2001-06-13 15:07:28 +02:00
|
|
|
use @option{-g}.
|
2001-06-03 00:33:30 +02:00
|
|
|
|
|
|
|
The solution is to compile the current version of GCC without
|
2001-06-13 15:07:28 +02:00
|
|
|
@option{-g}. That makes a working compiler which you can use to recompile
|
|
|
|
with @option{-g}.

Solaris 2 comes with a number of optional OS packages. Some of these
|
|
|
|
packages are needed to use GCC fully. If you did not install all
|
|
|
|
optional packages when installing Solaris, you will need to verify that
|
|
|
|
the packages that GCC needs are installed.
|
|
|
|
|
|
|
|
To check whether an optional package is installed, use
|
|
|
|
the @code{pkginfo} command. To add an optional package, use the
|
|
|
|
@code{pkgadd} command. For further details, see the Solaris
|
|
|
|
documentation.
|
|
|
|
|
|
|
|
For Solaris 2.0 and 2.1, GCC needs six packages: @samp{SUNWarc},
|
|
|
|
@samp{SUNWbtool}, @samp{SUNWesu}, @samp{SUNWhea}, @samp{SUNWlibm}, and
|
|
|
|
@samp{SUNWtoo}.
|
|
|
|
|
|
|
|
For Solaris 2.2, GCC needs an additional seventh package: @samp{SUNWsprot}.
|
|
|
|
|
|
|
|
On Solaris 2, trying to use the linker and other tools in
|
|
|
|
@file{/usr/ucb} to install GCC has been observed to cause trouble.
|
|
|
|
For example, the linker may hang indefinitely. The fix is to remove
|
|
|
|
@file{/usr/ucb} from your @code{PATH}.

All releases of GNU binutils prior to 2.11.1 have known bugs on this
|
|
|
|
platform. We recommend the use of GNU binutils 2.11.1 or the vendor
|
|
|
|
tools (Sun as, Sun ld).
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
Unfortunately, C++ shared libraries, including libstdc++, won't work
|
|
|
|
properly if assembled with Sun as: the linker will complain about
|
|
|
|
relocations in read-only sections, in the definition of virtual
|
|
|
|
tables. Also, Sun as fails to process long symbols resulting from
|
|
|
|
mangling template-heavy C++ function names.

Sun patch 107058-01 (1999-01-13) for SPARC Solaris 7 triggers a bug in
|
|
|
|
the dynamic linker. This problem (Sun bug 4210064) affects GCC 2.8
|
|
|
|
and later, including all EGCS releases. Sun formerly recommended
|
|
|
|
107058-01 for all Solaris 7 users, but around 1999-09-01 it started to
|
|
|
|
recommend it only for people who use Sun's compilers.
|
|
|
|
|
|
|
|
Here are some workarounds to this problem:
|
|
|
|
@itemize @bullet
|
|
|
|
@item
|
|
|
|
Do not install Sun patch 107058-01 until after Sun releases a
|
|
|
|
complete patch for bug 4210064. This is the simplest course to take,
|
|
|
|
unless you must also use Sun's C compiler. Unfortunately 107058-01
|
|
|
|
is preinstalled on some new Solaris-based hosts, so you may have to
|
|
|
|
back it out.

Install Sun patch 106950-03 (1999-05-25) or later. Nobody with
|
|
|
|
both 107058-01 and 106950-03 installed has reported the bug with GCC
|
|
|
|
and Sun's dynamic linker. This last course of action is riskiest,
|
|
|
|
for two reasons. First, you must install 106950 on all hosts that
|
|
|
|
run code generated by GCC; it doesn't suffice to install it only on
|
|
|
|
the hosts that run GCC itself. Second, Sun says that 106950-03 is
|
|
|
|
only a partial fix for bug 4210064, but Sun doesn't know whether the
|
|
|
|
partial fix is adequate for GCC. Revision -08 or later should fix
|
|
|
|
the bug, but (as of 1999-10-06) it is still being tested.

Sun bug 4296832 turns up when compiling X11 headers with GCC 2.95 or
|
2001-06-13 15:07:28 +02:00
|
|
|
newer: @command{g++} will complain that types are missing. These headers assume
|
|
|
|
that omitting the type means @code{int}; this assumption worked for C89 but
|
2001-05-12 00:10:54 +02:00
|
|
|
is wrong for C++, and is now wrong for C99 also.
|
|
|
|
|
2001-06-13 15:07:28 +02:00
|
|
|
@command{g++} accepts such (illegal) constructs with the option @option{-fpermissive}; it
|
|
|
|
will assume that any missing type is @code{int} (as defined by C89).

For Solaris 8, this is fixed by revision 24 or later of patch 108652
|
2001-05-12 00:10:54 +02:00
|
|
|
(for SPARCs) or 108653 (for Intels).
|
|
|
|
|
2001-06-13 05:38:52 +02:00
|
|
|
Solaris 8's linker fails to link some libjava programs if
|
|
|
|
previously-installed GCC java libraries already exist in the configured
|
|
|
|
prefix. For this reason, libgcj is disabled by default on Solaris 8.
|
|
|
|
If you use GNU ld, or if you don't have a previously-installed libgcj in
|
|
|
|
the same prefix, use @option{--enable-libgcj} to build and install the
|
|
|
|
Java libraries.

2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
The Sun V5.0 compilers are known to mis-compile GCC 2.95 and GCC 2.95.1,
|
|
|
|
which in turn causes GCC to fail its bootstrap comparison test.
|
|
|
|
GCC 2.95.2 has a workaround.

A bug in the SunOS4 linker will cause it to crash when linking
|
2001-06-13 15:07:28 +02:00
|
|
|
@option{-fPIC} compiled objects (and will therefore not allow you to build
|
2001-05-12 00:10:54 +02:00
|
|
|
shared libraries).
|
|
|
|
|
|
|
|
To fix this problem you can either use the most recent version of
|
|
|
|
binutils or get the latest SunOS4 linker patch (patch ID 100170-10)
|
|
|
|
from Sun's patch site.

On System V release 3, you may get this error message
|
|
|
|
while linking:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
ld fatal: failed to write symbol name @var{something}
|

|

This probably indicates that the disk is full or your ULIMIT won't allow
|
|
|
|
the file to be as large as it needs to be.
|
|
|
|
|
|
|
|
This problem can also result because the kernel parameter @code{MAXUMEM}
|
|
|
|
is too small. If so, you must regenerate the kernel and make the value
|
|
|
|
much larger. The default value is reported to be 1024; a value of 32768
|
|
|
|
is said to work. Smaller values may also work.
|
|
|
|
|
|
|
|
On System V, if you get an error like this,
|
|
|
|
|
|
|
|
@example
|
|
|
|
/usr/local/lib/bison.simple: In function `yyparse':
|
|
|
|
/usr/local/lib/bison.simple:625: virtual memory exhausted
|
|
|
|
@end example
|
|
|
|
|
|
|
|
@noindent
|
|
|
|
that too indicates a problem with disk space, ULIMIT, or @code{MAXUMEM}.

On a System V release 4 system, make sure @file{/usr/bin} precedes

Don't try compiling with Vax C (@code{vcc}). It produces incorrect code
|
|
|
|
in some cases (for example, when @code{alloca} is used).
|
|
|
|
|
|
|
|
Meanwhile, compiling @file{cp/parse.c} with pcc does not work because of
|
|
|
|
an internal table size limitation in that compiler. To avoid this
|
|
|
|
problem, compile just the GNU C compiler first, and use it to recompile

Don't use @option{-g} when compiling with the system's compiler. The
|
2001-06-03 00:33:30 +02:00
|
|
|
system's linker seems to be unable to handle such a large program with
|
|
|
|
debugging information.
|
|
|
|
|
|
|
|
The system's compiler runs out of capacity when compiling @file{stmt.c}
|
|
|
|
in GNU CC. You can work around this by building @file{cpp} in GNU CC
|
|
|
|
first, then use that instead of the system's preprocessor with the
|
|
|
|
system's C compiler to compile @file{stmt.c}. Here is how:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
mv /lib/cpp /lib/cpp.att
|
|
|
|
cp cpp /lib/cpp.gnu
|
|
|
|
echo '/lib/cpp.gnu -traditional $@{1+"$@@"@}' > /lib/cpp
|
|
|
|
chmod +x /lib/cpp
|
|
|
|
@end smallexample
|
|
|
|
|
|
|
|
The system's compiler produces bad code for some of the GNU CC
|
|
|
|
optimization files. So you must build the stage 2 compiler without
|
|
|
|
optimization. Then build a stage 3 compiler with optimization.
|
|
|
|
That executable should work. Here are the necessary commands:
|
|
|
|
|
|
|
|
@smallexample
|
|
|
|
make LANGUAGES=c CC=stage1/xgcc CFLAGS="-Bstage1/ -g"
|
|
|
|
make stage2
|
|
|
|
make CC=stage2/xgcc CFLAGS="-Bstage2/ -g -O"
|
|
|
|
@end smallexample
|
|
|
|
|
|
|
|
You may need to raise the ULIMIT setting to build a C++ compiler,
|
|
|
|
as the file @file{cc1plus} is larger than one megabyte.

@heading @anchor{older}Older systems
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
GCC contains support files for many older (1980s and early
|
|
|
|
1990s) Unix variants. For the most part, support for these systems
|
|
|
|
has not been deliberately removed, but it has not been maintained for
|
|
|
|
several years and may suffer from bitrot. Support from some systems
|
|
|
|
has been removed from GCC 3: fx80, ns32-ns-genix, pyramid, tahoe,
|
|
|
|
gmicro, spur; most of these targets had not been updated since GCC
|
|
|
|
version 1.
|
|
|
|
|
|
|
|
Support for older systems as targets for cross-compilation is less
|
|
|
|
problematic than support for them as hosts for GCC; if an enthusiast
|
|
|
|
wishes to make such a target work again (including resurrecting any
|
|
|
|
of the targets that never worked with GCC 2, starting from the last
|
|
|
|
CVS version before they were removed), patches
|
|
|
|
@uref{../contribute.html,,following the usual requirements}
|
|
|
|
would be likely to be accepted, since they should not affect the
|
|
|
|
support for more modern targets.
|
|
|
|
|
|
|
|
Support for old systems as hosts for GCC can cause problems if the
|
|
|
|
workarounds for compiler, library and operating system bugs affect the
|
|
|
|
cleanliness or maintainability of the rest of GCC. In some cases, to
|
|
|
|
bring GCC up on such a system, if still possible with current GCC, may
|
|
|
|
require first installing an old version of GCC which did work on that
|
|
|
|
system, and using it to compile a more recent GCC, to avoid bugs in
|
|
|
|
the vendor compiler. Old releases of GCC 1 and GCC 2 are available in
|
|
|
|
the old-releases directory on the
|
|
|
|
@uref{../mirrors.html,,GCC mirror sites}. Header bugs may generally
|
2001-06-01 20:08:19 +02:00
|
|
|
be avoided using @command{fixincludes}, but bugs or deficiencies in
|
|
|
|
libraries and the operating system may still cause problems.
|
2001-05-12 00:10:54 +02:00
|
|
|
|
|
|
|
For some systems, old versions of GNU binutils may also be useful,
|
|
|
|
and are available from pub/binutils/old-releases on
|
|
|
|
@uref{http://sources.redhat.com/mirrors.html,,sources.redhat.com mirror sites}.
|
|
|
|
|
|
|
|
Some of the information on specific systems above relates to
|
|
|
|
such older systems, but much of the information
|
|
|
|
about GCC on such systems (which may no longer be applicable to
|
|
|
|
current GCC) is to be found in the GCC texinfo manual.
