If you download the source distribution from one of the + DJGPP sites, just unzip it preserving the directory structure + running *ONE* of the following commands: + unzip32 bsn@PACKAGE_VERSION@s.zip or + djtarx bsn@PACKAGE_VERSION@s.zip or + pkunzip -d bsn@PACKAGE_VERSION@s.zip + and proceed to the paragraph 3.3, below. + +3.2.: Source distributions downloaded from one of the GNU FTP sites need + some more work to unpack, if LFN support is not available. If LFN is + available then you can extract the source files from the archive with + any unzip program and proceed to the paragraph 3.3, below. Any file + name issue will be handled by the the DJGPP configuration files. + To unpack the source distribution on SFN systems, first, you MUST use + the `djunpack' batch file to unzip the package. That is 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 `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 bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar.gz > djunpack.bat + djunpack bison-@VERSION@.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 Bison other than @VERSION@.) + + 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, and your version of + `djtar' doesn't support bzip2 decompression, you need to unpack it as + follows: + + bnzip2 bison-@VERSION@.tar.bz2 + djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar > djunpack.bat + djunpack bison-@VERSION@.tar + +3.3.: To build the binaries you will need the following binary packages: + djdev203.zip (or a later but NOT a prior version) + bsh204b.zip (or a later but NOT a prior version) + gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip, + perlNNNb.zip, shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip, + sedNNNb.zip and m4NNN.zip + + If you want to run the check you will need also: + difNNNb.zip + + NNN represents the latest version number of the binary packages. All + this packages can be found in the /v2gnu directory of any + ftp.delorie.com mirror. + You will need bsh204b.zip or later and *NOT* a prior version or + the build will fail. The same applies to djdev203.zip. Please note + that Bison requires m4-144b.zip or later to work properly. + +3.4.: If for some reason you want to reconfigure the package cd into the top + srcdir (bison-@TREE_VERSION@) and run the following commands: + del djgpp\config.cache + make clean + djgpp\config + + Please note that you *MUST* delete the config.cache file in the djgpp + subdir or you will not really reconfigure the sources because the + configuration informations will be read from the cache file instead + of being newly computed. + To build the programs in a directory other than where the sources are, + you must add the parameter that specifies the source directory, + e.g: + x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@ + + Lets assume you want to build the binaries in a directory placed on a + different drive (z:\build in this case) from where the sources are, + then you will run the following commands: + z: + md \build + cd \build + x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@ + + The order of the options and the srcdir option does not matter.
