[This file contains two alternative recipes for compiling X11 with GCC.
|
||||
The first alternative puts libgcc.a into the shared X library; the second
|
||||
does not. Neither alternative works on all kinds of systems.
|
||||
It may be that when using GCC 2.4, both alternatives work okay on
|
||||
relatively recent Sparc systems. The first alternative is likely
|
||||
not to work on a Sun 3 without hardware floating point.]
|
||||
|
||||
How to compile X11R5 (patch level 11) with GCC version 2:
|
||||
|
||||
The patches include support for building the shared libraries with GCC
|
||||
2 on the Sparc and 68k machines. This version includes the necessary
|
||||
parts of libgcc.a in the shared library for X, in case functions in
|
||||
that library need it. Thus the default behavior is now to build
|
||||
everything, including the libraries, with gcc.
|
||||
|
||||
If you build the shared library this way, it may not work with
|
||||
executables made with older versions of GCC (2.3.3 and earlier).
|
||||
If that happens, relink those executables with the latest GCC.
|
||||
IF YOU THINK YOU MIGHT COMPILE X FOR SOLARIS 2, then you really don't
|
||||
need this patch: get /contrib/R5.SunOS5.patch.tar.Z from
|
||||
export.lcs.mit.edu instead. It has everything you need to do the
|
||||
build for Solaris 2, sets you up to everything with GCC, and is
|
||||
backward compatible with SunOS 4.*. Get the README
|
||||
(/contrib/R5.SunOS5.patch.README at export) for more info.
|
||||
|
||||
If you see undefined symbols _dlopen, _dlsym, or _dlclose when linking
|
||||
with -lX11, compile and link against the file mit/util/misc/dlsym.c in
|
||||
the MIT X11R5 distribution. Alternatively, do dynamic linking
|
||||
by using a non-GNU ld.
|
||||

||||

|
||||

|
||||
|
||||
How to compile X11R5 (patch level 11) with GCC version 2:
|
||||
|
||||
The patches include support for building the shared libraries with GCC 2 on
|
||||
the Sparc and 68k machines.
|
||||
|
||||
NOTE: Such shared libraries built with GCC version 2.3 DID NOT WORK
|
||||
with executables previously linked using Sun CC! This is because
|
||||
neither those executables nor the gcc-compiled shared libraries contain
|
||||
libgcc.a. The shared libraries did work with executables linked using
|
||||
GCC (running the Sun linker, of course) because GCC tells the linker to
|
||||
link in libgcc.a. Because of these limitations the default behavior is
|
||||
to NOT build the shared libraries with gcc.
|
||||
|
||||
Changes in GCC 2.4 seem to have eliminated the problem, and such a
|
||||
shared library now seems work with all executables. If you want the
|
||||
gcc-compiled shared libraries turn on "Gcc2BuildLibs" in site.def. If
|
||||
you try this, please tell bug-gcc@prep.ai.mit.edu whether it works.
|
||||
|
||||
Sun forgot to include a static version of libdl.a with some versions
|
||||
of SunOS (4.1 mainly). If you see undefined symbols _dlopen, _dlsym,
|
||||
or _dlclose when linking with -lX11, compile and link against the file
|
||||
mit/util/misc/dlsym.c in the MIT X11R5 distribution.
