Unpacking and Installation -- quick overview

|
|
==========================
|
|
|
|
|
|
2000-05-11 09:55:25 +02:00
|
|
|
|
In this release, the GDB debugger sources, the generic GNU include
|
1999-04-16 03:35:26 +02:00
|
|
|
|
files, the BFD ("binary file description") library, the readline
|
|
|
|
|
library, and other libraries all have directories of their own
|
2002-04-26 01:26:23 +02:00
|
|
|
|
underneath the gdb-5.2 directory. The idea is that a variety of GNU
|
1999-04-16 03:35:26 +02:00
|
|
|
|
tools can share a common copy of these things. Be aware of variation
|
|
|
|
|
over time--for example don't try to build gdb with a copy of bfd from
|
2001-10-31 03:53:17 +01:00
|
|
|
|
a release other than the gdb release (such as a binutils release),
|
|
|
|
|
especially if the releases are more than a few weeks apart.
|
1999-04-16 03:35:26 +02:00
|
|
|
|
Configuration scripts and makefiles exist to cruise up and down this
|
|
|
|
|
directory tree and automatically build all the pieces in the right
|
|
|
|
|
order.
|
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
When you unpack the gdb-5.2.tar.gz file, you'll find a directory
|
|
|
|
|
called `gdb-5.2', which contains:

You can build GDB right in the source directory:
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
cd gdb-5.2
|
2001-10-31 03:53:17 +01:00
|
|
|
|
./configure
|
|
|
|
|
make
|
|
|
|
|
cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
2000-12-22 16:03:10 +01:00
|
|
|
|
However, we recommend that an empty directory be used instead.
|
|
|
|
|
This way you do not clutter your source tree with binary files
|
|
|
|
|
and will be able to create different builds with different
|
|
|
|
|
configuration options.
|
|
|
|
|
|
|
|
|
|
You can build GDB in any empty build directory:
|
|
|
|
|
|
2001-10-31 03:53:17 +01:00
|
|
|
|
mkdir build
|
|
|
|
|
cd build
|
2002-04-26 01:26:23 +02:00
|
|
|
|
<full path to your sources>/gdb-5.2/configure
|
2001-10-31 03:53:17 +01:00
|
|
|
|
make
|
|
|
|
|
cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
|
2000-12-22 16:03:10 +01:00
|
|
|
|
|
2000-04-12 18:51:27 +02:00
|
|
|
|
(Building GDB with DJGPP tools for MS-DOS/MS-Windows is slightly
|
2002-04-26 01:26:23 +02:00
|
|
|
|
different; see the file gdb-5.2/gdb/config/djgpp/README for details.)
|
2000-04-12 18:51:27 +02:00
|
|
|
|
|
2000-05-11 09:55:25 +02:00
|
|
|
|
This will configure and build all the libraries as well as GDB. If
|
|
|
|
|
`configure' can't determine your system type, specify one as its
|
|
|
|
|
argument, e.g., `./configure sun4' or `./configure decstation'.

|
|
|
|
If you get compiler errors during this stage, see the `Reporting
|
|
|
|
|
Bugs' section below; there are a few known problems.
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
2001-10-31 03:53:17 +01:00
|
|
|
|
GDB requires an ISO C (ANSI C) compiler. If you do not have an ISO
|
|
|
|
|
C compiler for your system, you may be able to download and install
|
|
|
|
|
the GNU CC compiler. It is available via anonymous FTP from the
|
|
|
|
|
directory `ftp://ftp.gnu.org/pub/gnu/gcc'.
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
2000-05-11 09:55:25 +02:00
|
|
|
|
GDB can be used as a cross-debugger, running on a machine of one
|
|
|
|
|
type while debugging a program running on a machine of another type.
|
|
|
|
|
See below.

More Documentation
|
|
|
|
|
******************
|
|
|
|
|
|
|
|
|
|
All the documentation for GDB comes as part of the machine-readable
|
2000-05-11 09:55:25 +02:00
|
|
|
|
distribution. The documentation is written in Texinfo format, which
|
|
|
|
|
is a documentation system that uses a single source file to produce
|
|
|
|
|
both on-line information and a printed manual. You can use one of the
|
|
|
|
|
Info formatting commands to create the on-line version of the
|
|
|
|
|
documentation and TeX (or `texi2roff') to typeset the printed version.
|
|
|
|
|
|
|
|
|
|
GDB includes an already formatted copy of the on-line Info version
|
|
|
|
|
of this manual in the `gdb/doc' subdirectory. The main Info file is
|
2002-04-26 01:26:23 +02:00
|
|
|
|
`gdb-5.2/gdb/doc/gdb.info', and it refers to subordinate files
|
2000-05-11 09:55:25 +02:00
|
|
|
|
matching `gdb.info*' in the same directory. If necessary, you can
|
|
|
|
|
print out these files, or read them with any editor; but they are
|
|
|
|
|
easier to read using the `info' subsystem in GNU Emacs or the
|
|
|
|
|
standalone `info' program, available as part of the GNU Texinfo
|
|
|
|
|
distribution.
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
|
|
|
|
If you want to format these Info files yourself, you need one of the
|
|
|
|
|
Info formatting programs, such as `texinfo-format-buffer' or
|
|
|
|
|
`makeinfo'.
|
|
|
|
|
|
|
|
|
|
If you have `makeinfo' installed, and are in the top level GDB
|
2002-04-26 01:26:23 +02:00
|
|
|
|
source directory (`gdb-5.2', in the case of version 5.2), you can make
|
1999-04-16 03:35:26 +02:00
|
|
|
|
the Info file by typing:
|
|
|
|
|
|
2001-10-31 03:53:17 +01:00
|
|
|
|
cd gdb/doc
|
|
|
|
|
make info
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
|
|
|
|
If you want to typeset and print copies of this manual, you need
|
|
|
|
|
TeX, a program to print its DVI output files, and `texinfo.tex', the
|
|
|
|
|
Texinfo definitions file. This file is included in the GDB
|
2002-04-26 01:26:23 +02:00
|
|
|
|
distribution, in the directory `gdb-5.2/texinfo'.
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
|
|
|
|
TeX is a typesetting program; it does not print files directly, but
|
|
|
|
|
produces output files called DVI files. To print a typeset document,
|
|
|
|
|
you need a program to print DVI files. If your system has TeX
|
|
|
|
|
installed, chances are it has such a program. The precise command to
|
|
|
|
|
use depends on your system; `lpr -d' is common; another (for PostScript
|
|
|
|
|
devices) is `dvips'. The DVI print command may require a file name
|
|
|
|
|
without any extension or a `.dvi' extension.
|
|
|
|
|
|
|
|
|
|
TeX also requires a macro definitions file called `texinfo.tex'.
|
|
|
|
|
This file tells TeX how to typeset a document written in Texinfo
|
|
|
|
|
format. On its own, TeX cannot read, much less typeset a Texinfo file.
|
|
|
|
|
`texinfo.tex' is distributed with GDB and is located in the
|
2002-04-26 01:26:23 +02:00
|
|
|
|
`gdb-5.2/texinfo' directory.
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
|
|
|
|
If you have TeX and a DVI printer program installed, you can typeset
|
|
|
|
|
and print this manual. First switch to the the `gdb' subdirectory of
|
2002-04-26 01:26:23 +02:00
|
|
|
|
the main source directory (for example, to `gdb-5.2/gdb') and then type:
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
2001-10-31 03:53:17 +01:00
|
|
|
|
make doc/gdb.dvi
|
2001-07-25 16:58:38 +02:00
|
|
|
|
|
|
|
|
|
If you prefer to have the manual in PDF format, type this from the
|
|
|
|
|
`gdb/doc' subdirectory of the main source directory:
|
|
|
|
|
|
2001-10-31 03:53:17 +01:00
|
|
|
|
make gdb.pdf
|
2001-07-25 16:58:38 +02:00
|
|
|
|
|
|
|
|
|
For this to work, you will need the PDFTeX package to be installed.

Installing GDB
|
|
|
|
|
**************
|
|
|
|
|
|
|
|
|
|
GDB comes with a `configure' script that automates the process of
|
|
|
|
|
preparing GDB for installation; you can then use `make' to build the
|
|
|
|
|
`gdb' program.
|
|
|
|
|
|
|
|
|
|
The GDB distribution includes all the source code you need for GDB in
|
|
|
|
|
a single directory, whose name is usually composed by appending the
|
|
|
|
|
version number to `gdb'.
|
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
For example, the GDB version 5.2 distribution is in the `gdb-5.2'
|
1999-04-16 03:35:26 +02:00
|
|
|
|
directory. That directory contains:
|
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
`gdb-5.2/{COPYING,COPYING.LIB}'

Note: the following instructions are for building GDB on Unix or
|
|
|
|
|
Unix-like systems. Instructions for building with DJGPP for
|
|
|
|
|
MS-DOS/MS-Windows are in the file gdb/config/djgpp/README.
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
|
|
|
|
The simplest way to configure and build GDB is to run `configure'
|
|
|
|
|
from the `gdb-VERSION-NUMBER' source directory, which in this example
|
2002-04-26 01:26:23 +02:00
|
|
|
|
is the `gdb-5.2' directory.

|
|
|
|
First switch to the `gdb-VERSION-NUMBER' source directory if you are
|
|
|
|
|
not already in it; then run `configure'.
|
|
|
|
|
|
|
|
|
|
For example:
|
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
cd gdb-5.2
|
2001-10-31 03:53:17 +01:00
|
|
|
|
./configure
|
|
|
|
|
make
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
|
|
|
|
Running `configure' followed by `make' builds the `bfd',
|
|
|
|
|
`readline', `mmalloc', and `libiberty' libraries, then `gdb' itself.
|
|
|
|
|
The configured source files, and the binaries, are left in the
|
|
|
|
|
corresponding source directories.
|
|
|
|
|
|
|
|
|
|
`configure' is a Bourne-shell (`/bin/sh') script; if your system
|
|
|
|
|
does not recognize this automatically when you run a different shell,
|
|
|
|
|
you may need to run `sh' on it explicitly:
|
|
|
|
|
|
2001-10-31 03:53:17 +01:00
|
|
|
|
sh configure
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
|
|
|
|
If you run `configure' from a directory that contains source
|
2002-04-26 01:26:23 +02:00
|
|
|
|
directories for multiple libraries or programs, such as the `gdb-5.2'
|
|
|
|
|
source directory for version 5.2, `configure' creates configuration
|
1999-04-16 03:35:26 +02:00
|
|
|
|
files for every directory level underneath (unless you tell it not to,
|
|
|
|
|
with the `--norecursion' option).
|
|
|
|
|
|
|
|
|
|
You can run the `configure' script from any of the subordinate
|
|
|
|
|
directories in the GDB distribution, if you only want to configure that
|
|
|
|
|
subdirectory; but be sure to specify a path to it.
|
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
For example, with version 5.2, type the following to configure only
|
1999-04-16 03:35:26 +02:00
|
|
|
|
the `bfd' subdirectory:
|
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
cd gdb-5.2/bfd
|
2001-10-31 03:53:17 +01:00
|
|
|
|
../configure
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
|
|
|
|
You can install `gdb' anywhere; it has no hardwired paths. However,
|
|
|
|
|
you should make sure that the shell on your path (named by the `SHELL'
|
|
|
|
|
environment variable) is publicly readable. Remember that GDB uses the
|
|
|
|
|
shell to start your program--some systems refuse to let GDB debug child
|
|
|
|
|
processes whose programs are not readable.
|

|
Compiling GDB in another directory
|
|
|
|
|
==================================
|
|
|
|
|
|
|
|
|
|
If you want to run GDB versions for several host or target machines,
|
|
|
|
|
you need a different `gdb' compiled for each combination of host and
|
|
|
|
|
target. `configure' is designed to make this easy by allowing you to
|
|
|
|
|
generate each configuration in a separate subdirectory, rather than in
|
|
|
|
|
the source directory. If your `make' program handles the `VPATH'
|
|
|
|
|
feature correctly (GNU `make' and SunOS 'make' are two that should),
|
|
|
|
|
running `make' in each of these directories builds the `gdb' program
|
|
|
|
|
specified there.
|
|
|
|
|
|
|
|
|
|
To build `gdb' in a separate directory, run `configure' with the
|
|
|
|
|
`--srcdir' option to specify where to find the source. (You also need
|
|
|
|
|
to specify a path to find `configure' itself from your working
|
|
|
|
|
directory. If the path to `configure' would be the same as the
|
|
|
|
|
argument to `--srcdir', you can leave out the `--srcdir' option; it
|
|
|
|
|
will be assumed.)
|
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
For example, with version 5.2, you can build GDB in a separate
|
1999-04-16 03:35:26 +02:00
|
|
|
|
directory for a Sun 4 like this:
|
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
cd gdb-5.2
|
1999-04-16 03:35:26 +02:00
|
|
|
|
mkdir ../gdb-sun4
|
|
|
|
|
cd ../gdb-sun4
|
2002-04-26 01:26:23 +02:00
|
|
|
|
../gdb-5.2/configure
|
1999-04-16 03:35:26 +02:00
|
|
|
|
make
|
|
|
|
|
|
|
|
|
|
When `configure' builds a configuration using a remote source
|
|
|
|
|
directory, it creates a tree for the binaries with the same structure
|
|
|
|
|
(and using the same names) as the tree under the source directory. In
|
|
|
|
|
the example, you'd find the Sun 4 library `libiberty.a' in the
|
|
|
|
|
directory `gdb-sun4/libiberty', and GDB itself in `gdb-sun4/gdb'.
|
|
|
|
|
|
|
|
|
|
One popular reason to build several GDB configurations in separate
|
|
|
|
|
directories is to configure GDB for cross-compiling (where GDB runs on
|
|
|
|
|
one machine--the host--while debugging programs that run on another
|
|
|
|
|
machine--the target). You specify a cross-debugging target by giving
|
|
|
|
|
the `--target=TARGET' option to `configure'.
|
|
|
|
|
|
|
|
|
|
When you run `make' to build a program or library, you must run it
|
|
|
|
|
in a configured directory--whatever directory you were in when you
|
|
|
|
|
called `configure' (or one of its subdirectories).
|
|
|
|
|
|
|
|
|
|
The `Makefile' that `configure' generates in each source directory
|
|
|
|
|
also runs recursively. If you type `make' in a source directory such
|
2002-04-26 01:26:23 +02:00
|
|
|
|
as `gdb-5.2' (or in a separate configured directory configured with
|
|
|
|
|
`--srcdir=PATH/gdb-5.2'), you will build all the required libraries,
|
1999-04-16 03:35:26 +02:00
|
|
|
|
and then build GDB.
|
|
|
|
|
|
|
|
|
|
When you have multiple hosts or targets configured in separate
|
|
|
|
|
directories, you can run `make' on them in parallel (for example, if
|
|
|
|
|
they are NFS-mounted on each of the hosts); they will not interfere
|
|
|
|
|
with each other.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Specifying names for hosts and targets
|
|
|
|
|
======================================
|
|
|
|
|
|
|
|
|
|
The specifications used for hosts and targets in the `configure'
|
|
|
|
|
script are based on a three-part naming scheme, but some short
|
|
|
|
|
predefined aliases are also supported. The full naming scheme encodes
|
|
|
|
|
three pieces of information in the following pattern:
|
|
|
|
|
|
|
|
|
|
ARCHITECTURE-VENDOR-OS
|
|
|
|
|
|
|
|
|
|
For example, you can use the alias `sun4' as a HOST argument or in a
|
|
|
|
|
`--target=TARGET' option. The equivalent full name is
|
|
|
|
|
`sparc-sun-sunos4'.
|
|
|
|
|
|
|
|
|
|
The `configure' script accompanying GDB does not provide any query
|
|
|
|
|
facility to list all supported host and target names or aliases.
|
|
|
|
|
`configure' calls the Bourne shell script `config.sub' to map
|
|
|
|
|
abbreviations to full names; you can read the script, if you wish, or
|
|
|
|
|
you can use it to test your guesses on abbreviations--for example:
|
|
|
|
|
|
|
|
|
|
% sh config.sub sun4
|
|
|
|
|
sparc-sun-sunos4.1.1
|
|
|
|
|
% sh config.sub sun3
|
|
|
|
|
m68k-sun-sunos4.1.1
|
|
|
|
|
% sh config.sub decstation
|
|
|
|
|
mips-dec-ultrix4.2
|
|
|
|
|
% sh config.sub hp300bsd
|
|
|
|
|
m68k-hp-bsd
|
|
|
|
|
% sh config.sub i386v
|
|
|
|
|
i386-pc-sysv
|
|
|
|
|
% sh config.sub i786v
|
|
|
|
|
Invalid configuration `i786v': machine `i786v' not recognized
|
|
|
|
|
|
|
|
|
|
`config.sub' is also distributed in the GDB source directory
|
2002-04-26 01:26:23 +02:00
|
|
|
|
(`gdb-5.2', for version 5.2).

`configure' options
|
|
|
|
|
===================
|
|
|
|
|
|
|
|
|
|
Here is a summary of the `configure' options and arguments that are
|
|
|
|
|
most often useful for building GDB. `configure' also has several other
|
|
|
|
|
options not listed here. *note : (configure.info)What Configure Does,
|
|
|
|
|
for a full explanation of `configure'.
|
|
|
|
|
|
|
|
|
|
configure [--help]
|
|
|
|
|
[--prefix=DIR]
|
|
|
|
|
[--srcdir=PATH]
|
|
|
|
|
[--norecursion] [--rm]
|
|
|
|
|
[--enable-build-warnings]
|
|
|
|
|
[--target=TARGET]
|
|
|
|
|
[--host=HOST]
|
|
|
|
|
[HOST]
|
|
|
|
|
|
|
|
|
|
You may introduce options with a single `-' rather than `--' if you
|
|
|
|
|
prefer; but you may abbreviate option names if you use `--'.
|
|
|
|
|
|
|
|
|
|
`--help'
|
|
|
|
|
Display a quick summary of how to invoke `configure'.
|
|
|
|
|
|
|
|
|
|
`-prefix=DIR'
|
|
|
|
|
Configure the source to install programs and files under directory
|
|
|
|
|
`DIR'.
|
|
|
|
|
|
|
|
|
|
`--srcdir=PATH'
|
|
|
|
|
*Warning: using this option requires GNU `make', or another `make'
|
|
|
|
|
that compatibly implements the `VPATH' feature.*
|
|
|
|
|
Use this option to make configurations in directories separate
|
|
|
|
|
from the GDB source directories. Among other things, you can use
|
|
|
|
|
this to build (or maintain) several configurations simultaneously,
|
|
|
|
|
in separate directories. `configure' writes configuration
|
|
|
|
|
specific files in the current directory, but arranges for them to
|
|
|
|
|
use the source in the directory PATH. `configure' will create
|
|
|
|
|
directories under the working directory in parallel to the source
|
|
|
|
|
directories below PATH.
|
|
|
|
|
|
|
|
|
|
`--norecursion'
|
|
|
|
|
Configure only the directory level where `configure' is executed;
|
|
|
|
|
do not propagate configuration to subdirectories.
|
|
|
|
|
|
|
|
|
|
`--rm'
|
|
|
|
|
Remove the configuration that the other arguments specify.
|
|
|
|
|
|
|
|
|
|
`--enable-build-warnings'
|
|
|
|
|
When building the GDB sources, ask the compiler to warn about any
|
|
|
|
|
code which looks even vaguely suspicious. You should only using
|
|
|
|
|
this feature if you're compiling with GNU CC. It passes the
|
|
|
|
|
following flags:
|
2000-05-11 09:55:25 +02:00
|
|
|
|
-Wimplicit
|
|
|
|
|
-Wreturn-type

|
|
|
-Wparentheses
|
1999-04-16 03:35:26 +02:00
|
|
|
|
-Wpointer-arith
|
|
|
|
|
|
|
|
|
|
`--target=TARGET'
|
|
|
|
|
Configure GDB for cross-debugging programs running on the specified
|
|
|
|
|
TARGET. Without this option, GDB is configured to debug programs
|
|
|
|
|
that run on the same machine (HOST) as GDB itself.
|
|
|
|
|
|
|
|
|
|
There is no convenient way to generate a list of all available
|
|
|
|
|
targets.
|
|
|
|
|
|
|
|
|
|
`--host=HOST'
|
|
|
|
|
Configure GDB to run on the specified HOST.
|
|
|
|
|
|
|
|
|
|
There is no convenient way to generate a list of all available
|
|
|
|
|
hosts.
|
|
|
|
|
|
|
|
|
|
`HOST ...'
|
|
|
|
|
Same as `--host=HOST'. If you omit this, GDB will guess; it's
|
|
|
|
|
quite accurate.
|
|
|
|
|
|
|
|
|
|
`configure' accepts other options, for compatibility with configuring
|
|
|
|
|
other GNU tools recursively; but these are the only options that affect
|
|
|
|
|
GDB or its supporting libraries.

of remote stubs to be used with remote.c. They are designed to run

Remote-vx.c and the vx-share subdirectory contain a remote

|
interface for the VxWorks realtime kernel, which communicates over TCP

other remote- via-ethernet back ends.

Remote-udi.c and the 29k-share subdirectory contain a remote
|
|
|
|
|
interface for AMD 29000 programs, which uses the AMD "Universal Debug

|
Interface". This allows GDB to talk to software simulators,
|
|
|
|
|
emulators, and/or bare hardware boards, via network or serial
|
|
|
|
|
interfaces. Note that GDB only provides an interface that speaks UDI,
|
|
|
|
|
not a complete solution. You will need something on the other end
|
|
|
|
|
that also speaks UDI.

Reporting Bugs in GDB
|
|
|
|
|
=====================
|
|
|
|
|
|
|
|
|
|
There are several ways of reporting bugs in GDB. The prefered
|
|
|
|
|
method is to use the World Wide Web:
|
|
|
|
|
|
|
|
|
|
http://www.gnu.org/software/gdb/bugs/
|
|
|
|
|
|
|
|
|
|
As an alternative, the bug report can be submitted, via e-mail, to the
|
|
|
|
|
address "bug-gdb@gnu.org".
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
2002-04-07 21:09:58 +02:00
|
|
|
|
When submitting a bug, please include the GDB version number (e.g.,
|
2002-04-26 01:26:23 +02:00
|
|
|
|
gdb-5.2), and how you configured it (e.g., "sun4" or "mach386 host,
|
2002-04-07 21:09:58 +02:00
|
|
|
|
i586-intel-synopsys target"). Since GDB now supports so many
|
2000-05-11 09:55:25 +02:00
|
|
|
|
different configurations, it is important that you be precise about
|
|
|
|
|
this. If at all possible, you should include the actual banner that
|
|
|
|
|
GDB prints when it starts up, or failing that, the actual configure
|
|
|
|
|
command that you used when configuring GDB.

Writing Code for GDB
|
|
|
|
|
=====================
|
|
|
|
|
|
2000-05-11 09:55:25 +02:00
|
|
|
|
There is a lot of information about writing code for GDB in the
|
1999-04-16 03:35:26 +02:00
|
|
|
|
internals manual, distributed with GDB in gdb/doc/gdbint.texinfo. You
|
|
|
|
|
can read it by hand, print it by using TeX and texinfo, or process it
|
|
|
|
|
into an `info' file for use with Emacs' info mode or the standalone
|
|
|
|
|
`info' program.

If you are pondering writing anything but a short patch, especially
|
1999-04-16 03:35:26 +02:00
|
|
|
|
take note of the information about copyrights in the node Submitting
|
|
|
|
|
Patches. It can take quite a while to get all the paperwork done, so
|
|
|
|
|
we encourage you to start that process as soon as you decide you are
|
|
|
|
|
planning to work on something, or at least well ahead of when you
|
|
|
|
|
think you will be ready to submit the patches.

GDB Testsuite
|
|
|
|
|
=============
|
|
|
|
|
|
2000-05-11 09:55:25 +02:00
|
|
|
|
Included with the GDB distribution is a DejaGNU based testsuite
|
|
|
|
|
that can either be used to test your newly built GDB, or for
|
|
|
|
|
regression testing a GDB with local modifications.
|
|
|
|
|
|
|
|
|
|
Running the testsuite requires the prior installation of DejaGNU,
|
|
|
|
|
which is generally available via ftp. The directory
|
2002-02-23 21:59:55 +01:00
|
|
|
|
ftp://sources.redhat.com/pub/dejagnu/ will contain a recent snapshot.
|
|
|
|
|
Once DejaGNU is installed, you can run the tests in one of the
|
|
|
|
|
following ways:
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
(1) cd gdb-5.2
|
2000-05-11 09:55:25 +02:00
|
|
|
|
make check-gdb
|
|
|
|
|
|
|
|
|
|
or
|
1999-04-16 03:35:26 +02:00
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
(2) cd gdb-5.2/gdb
|
1999-04-16 03:35:26 +02:00
|
|
|
|
make check
|
|
|
|
|
|
|
|
|
|
or
|
|
|
|
|
|
2002-04-26 01:26:23 +02:00
|
|
|
|
(3) cd gdb-5.2/gdb/testsuite
|
1999-04-16 03:35:26 +02:00
|
|
|
|
make site.exp (builds the site specific file)
|
|
|
|
|
runtest -tool gdb GDB=../gdb (or GDB=<somepath> as appropriate)
|
|
|
|
|
|
2000-05-11 09:55:25 +02:00
|
|
|
|
The last method gives you slightly more control in case of problems
|
|
|
|
|
with building one or more test executables or if you are using the
|
|
|
|
|
testsuite `standalone', without it being part of the GDB source tree.
