It is available from the GNU FTP site: ftp://ftp.gnu.org/gnu/gdb/gdb-5.0.tar.gz It will take some time until precompiled binary of the DJGPP port is available from SimTel.NET: I would like to run it through its test suite, resolve any problems I find, get the packaging right on all supported platforms, etc. It's possible that the port won't be ready before a few weeks pass. However, since this GDB release supports DJGPP out of the box, I'd like to encourage people who want the latest-and-greatest (and can sustain downloading a 12-MByte compressed archive ;-) to please fetch it, build it on their machines, and use it, in the hope that this will reveal any problems, both in the build procedure and in the DJGPP port itself, that were not caught during the pretest. Those who do download this release, are requested to please report here any problems they see. Unpacking and building the package with DJGPP tools is a bit complicated, so I append below the relevant portion of the DJGPP-specific README file. Please read this *before* you unpack! One last comment: due to last-minute changes, if you unpack the distribution on a non-LFN platforms, DJTAR will ask for a new name for a couple of files. Just hit [Enter] when it does (these files are not used in the DJGPP port). ================================================================= Rebuilding GDB from sources =========================== 1. Prerequisites ------------- To build the package, you will need the DJGPP development environment (GCC, header files, and the libraries), and also DJGPP ports of the following tools: - GNU Make 3.78.1 or later - Bash 2.03 or later - GNU Sed - GNU Fileutils - GNU Textutils 2.0 or later - GNU Sh-utils - GNU Grep 2.4 or later - GNU Findutils - GNU Awk 3.04 or later - GNU Bison (only if you change one of the gdb/*.y files) - Groff (only if you need to format the man pages) - GNU Diffutils (only if you run the test suite) These programs should be available from the DJGPP sites, in the v2gnu directory. In addition, the configuration script invokes the `update' and `utod' utilities which are part of the basic DJGPP development kit (djdevNNN.zip). 2. Unpacking the sources --------------------- If you download the source distribution from one of the DJGPP sites, just unzip it while preserving the directory structure (I suggest to use unzip32.exe available with the rest of DJGPP), and proceed to the section "How to build" below. Source distributions downloaded from one of the GNU FTP sites need some more work to unpack. First, you MUST use the `djunpack' batch file to unzip the package. That's because some file names in the official distributions need to be changed to avoid problems on the various platforms supported by DJGPP. `djunpack' invokes the `djtar' program (that is part of the basic DJGPP development kit) to rename these files on the fly given a file with name mappings; the distribution includes a file `gdb/config/djgpp/fnchange.lst' with the necessary mappings. So you need first to retrieve that batch file, and then invoke it to unpack the distribution. Here's how: djtar -x -p -o gdb-5.0/djunpack.bat gdb-5.0.tar.gz > djunpack.bat djunpack gdb-5.0.tar.gz (The name of the distribution archive and the leading directory of the path to `djunpack.bat' in the distribution will be different for versions of GDB other than 5.0.) If the argument to `djunpack.bat' include leading directories, it MUST be given with the DOS-style backslashes; Unix-style forward slashes will NOT work. If the distribution comes as a .tar.bz2 archive, you need to unpack it as follows: bnzip2 gdb-5.0.tar.bz2 djtar -x -p -o gdb-5.0/djunpack.bat gdb-5.0.tar > djunpack.bat djunpack gdb-5.0.tar 3. How to build ------------ To build a package downloaded from a GNU FTP site, you will need o configure it first. You will also need to configure it if you want to change the configuration options (e.g., compile with support for the GDBMI interface). To configure GDB, type this command: sh ./gdb/config/djgpp/djconfig.sh This script checks the unpacked distribution, then edits the configure scripts in the various subdirectories, to make them suitable for DJGPP, and finally invokes the top-level configure script, which recursively configures all the subdirectories. You may pass optional switches to djconfig.sh. It accepts all the switches accepted by the original GDB configure script. These switches are described in the file gdb/README, and their full list be displayed by running the following command: sh ./gdb/configure --help NOTE: if you *do* use optional command-line switches, you MUST pass to the script the name of the directory where GDB sources are unpacked--even if you are building GDB in-place! For example: sh ./gdb/config/djgpp/djconfig.sh . --enable-gdbmi It is also possible to build GDB in a directory that is different from the one where the sources were unpacked. In that case, you have to pass the source directory as the first argument to the script: sh ./gdb/config/djgpp/djconfig.sh d:/gnu/gdb-5.0 You MUST use forward slashes in the first argument. After the configure script finishes, run Make: make If you want to produce the documentation (for example, if you changed some of the Texinfo sources), type this: make info When Make finishes, you can install the package: make -k install prefix='${DJDIR}' INSTALL='ginstall -c' The above doesn't install the docs; for that you will need to say this: make -k install-info prefix='${DJDIR}' INSTALL='ginstall -c' (The -k switch is required, because some unneeded targets that are part of the install process fail; -k lets Make run to completion nonetheless.)
