See the +GNU General Public License for more details. + +You should have received a copy of the GNU General Public License +along with this program. If not, see <http://www.gnu.org/licenses/>. + + +1.: DJGPP specific changes. + ======================= + + The DJGPP port of Bison offers LFN and SFN support depending on which + OS it is running. If LFN support is available or not is determinated at + run time. If LFN support is available (DOS session under Win9X, Win2K, + WinXP, etc.) the standard posix file name extensions will be used. + These are: y.tab.c, y.tab.c++, y.tab.h, y.output, etc. If only SFN + support is available (plain DOS), then the standard MSDOS short file + names will be used. These are: y_tab.c, y_tab.h, y.out, etc. + It should be noticed that this bison version needs the m4 program as + back end to generate the parser file (y.tab.c etc.) from the skeleton + files. This implies that m4 must always be installed to get bison + working. m4 will use a couple of m4 scripts that will be installed in + /dev/env/DJDIR/share/bison and shall not be removed. + It should also be noticed that the skeleton files bison.simple and + bison.hairy are no longer supported. This applies also to the environ- + ment variables BISON_HAIRY and BISON_SIMPLE. Those variables are *no* + longer honored at all. + The kind of skeleton file bison.hairy is no longer supported at all. + The skeleton file bison.simple is now called yacc.c and is an m4 script. + The other two skeleton files supported by this bison version are glr.c + and lalr1.cc. The first one is a generalized LR C parser based on + Bison's LALR(1) tables and the second one is a experimental C++ parser + class. + As has been told before, bison uses m4 to generate the parser file. + This is done by forking and using pipes for the IPC. MSDOS does not + support this functionality so this has been reproduced in the usual + way by redirecting stdin and stdout of bison and m4 to temporary files + and processing these files in sequence. + It should be noticed that due to the great amount of file names that do + not cleanly map to 8.3 file names, you will need an OS with LFN support + to configure and compile the sources. On Win98 this implies that the + generation of numeric tails for 8.3 file name aliases must be enabled + or the compilation will fail. + + + Please **read** the docs. + + +2.: Installing the binary package. + ============================== + +2.1.: Copy the binary distribution into the top DJGPP installation directory, + just unzip it preserving the directory structure running *ONE* of the + following commands: + unzip32 bsn@PACKAGE_VERSION@b.zip or + djtarx bsn@PACKAGE_VERSION@b.zip or + pkunzip -d bsn@PACKAGE_VERSION@b.zip + + + +3.: Building the binaries from sources. + =================================== + +3.1.: Create a temporary directory and copy the source package into the + directory. 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. You + *MUST* use forward slashes to specify the source directory. + + The batch file will set same environment variables, make MSDOS specific + modifications to the Makefile.in's and supply all other needed options + to the configure script. + +3.5.: To compile the package run from the top srcdir the command: + make + +3.6.: Now you can run the tests if you like. From the top srcdir run the + command: + make check + + No test should fail but the tests #131 (Doxygen Public Documentation) + and #132 (Doxygen Private Documentation) will be skipped. Please note + that the testsuite only works with LFN available. On plain DOS, most + of the tests will fail due to invalid DOS names. + +3.7.: To install the binaries, header, library, catalogs, and info docs + run the following command from the top srcdir: + make install + + This will install the products into your DJGPP installation tree given + by the default prefix "/dev/env/DJDIR". If you prefer to install them + into some other directory you will have to set prefix to the appropiate + value: + make install prefix=z:/some/other/place + + + + Send GNU bison specific bug reports to <bug-bison@gnu.org>. + Send suggestions and bug reports concerning the DJGPP port to + comp.os.msdos.djgpp or <djgpp@delorie.com>. + + +Enjoy. + + Guerrero, Juan Manuel <juan.guerrero@gmx.de> |
