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), 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. All the changes to the sources
- are documented in the djgpp/diffs file.
-
- 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
+ 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.
+ 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-2.1/djgpp/djunpack.bat bison-2.1.tar.gz > djunpack.bat
- djunpack bison-2.1.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 2.1.)
-
- 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-2.1.tar.bz2
- djtar -x -p -o bison-2.1/djgpp/djunpack.bat bison-2.1.tar > djunpack.bat
- djunpack bison-2.1.tar
+ 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.

+ 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)
- gcc400b.zip, gpp400b.zip, bnu215b.zip, mak3791b.zip,
- fil40b.zip, shl20jb.zip, txt20b.zip,
- txi48b.zip, grep24b.zip, sed414b.zip,
- m4-144b.zip.
-
- If you want to run the check you will need also:
- dif281b.zip
-
- All this packages can be found in the v2gnu directory of any
- ftp.delorie.com mirror.
- You will need bsh203b.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. All the
- other packages are the ones I have used to build the binaries
- from this source. Previuos versions of this packages may do the
- job as well but I have not tested this.

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
+ make
3.6.: Now you can run the tests if you like. From the top srcdir run the
- command:
- make check
+ command:
+ make check
- No test should fail.
- 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
+ run the following command from the top srcdir:
+ make install
- This will install the products into your DJGPP installation tree given
