+       How to build and install the DJGPP native version of GDB
+       ********************************************************
+
+General
+=======
+
+GDB built with DJGPP supports native DJGPP debugging, whereby you run
+gdb.exe and the program being debugged on the same machine.  In
+addition, this version supports remote debugging via a serial port,
+provided that the target machine has a GDB-compatible debugging stub
+which can be linked with the target program (see the section "Remote
+Serial" in the GDB manual for more details).
+
+
+Installation of the binary distribution
+=======================================
+
+Simply unzip the gdbNNNb.zip file (where NNN is the version number)
+from the top DJGPP installation directory.  Be sure to preserve the
+directory structure while you unzip (use -d switch if you do this with
+PKUNZIP).  On Windows 9X and Windows 2000, use an unzip program which
+supports long file names; one such program is unzip32.exe, available
+from the DJGPP sites.
+
+If you need the libraries which are built as part of GDB, install the
+companion file gdbNNNa.zip.  This allows to develop applications which
+use the same functions as GDB.  For example, you can build your own
+front end to the debugger.
+
+
+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 `djtar' program 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.  `djtar' can rename 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 file, and then invoke `djtar' to unpack
+the distribution.  Here's how:
+
+
+ djtar -x -p -o gdb-5.0/gdb/config/djgpp/fnchange.lst gdb-5.0.tar.gz > lst
+ djtar -x -n lst gdb-5.0.tar.gz
+
+(The name of the distribution archive and the top-level directory will
+be different for versions other than 5.0.)
+
+
+3. How to build
+   ------------
+
+The source distribution available from DJGPP archives is already
+configured for DJGPP v2.x, so if you only want to compile it, just
+invoke Make:
+
+               make
+
+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
+
+When Make finishes, you can install the package:
+
+       make install INSTALL='/dev/env/DJDIR/bin/ginstall -c'
+
+The above doesn't install the docs; for that you will need to say
+this:
+
+       make -k install-info INSTALL='/dev/env/DJDIR/bin/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.)
+
+The test suite has been made to work with DJGPP.  If you make a change
+in some of the programs, or want to be sure you have a fully
+functional GDB executable, it is a good idea to run the test suite.
+You cannot use "make check" for that, since it will want to run the
+`dejagnu' utility which GDB doesn't support.  Instead, use the special
+script gdb/config/djgpp/djcheck.sh, like this:
+
+               cd gdb/testsuite
+               sh ../config/djgpp/djcheck.sh
+
+This will run for a while and should not print anything.  Any test
+that fails to produce the expected output will cause the diffs between
+the expected and the actual output be printed, and in addition will
+leave behind a file SOMETHING.tst (where SOMETHING is the name of one
+of the tests).  You should compare each of the *.tst files with the
+corresponding *.out file and convince yourself that the differences do
+not indicate a real problem.  Examples of differences you can
+disregard are changes in the copyright blurb printed by GDB, values of
+unitialized variables, addresses of global variables like argv[] and
+envp[] (which depend on the size of your environment), etc.
+
+Note that djcheck.sh only recurses into those of the subdirectories of
+the test suite which test features supported by the DJGPP port of GDB.
+For example, the tests in the gdb.gdbtk, gdb.threads, and gdb.hp
+directories are not run.
+
+
+Enjoy,
+                                    Eli Zaretskii <eliz@is.elta.co.il>
