201.:     DJGPP specific changes.
21	=======================
22
23	The DJGPP port of Bison offers LFN and SFN support depending on which
24	OS it is running. If LFN support is available or not is determinated at
25	run time.  If LFN support is available (DOS session under Win9X, Win2K,
26	WinXP, etc.) the standard posix file name extensions will be used.
27	These are: y.tab.c, y.tab.c++, y.tab.h, y.output, etc.  If only SFN
28	support is available (plain DOS), then the standard MSDOS short file
29	names will be used. These are: y_tab.c, y_tab.h, y.out, etc.
30	It should be noticed that this bison version needs the m4 program as
31	back end to generate the parser file (y.tab.c etc.) from the skeleton
32	files.  This implies that m4 must always be installed to get bison
33	working.  m4 will use a couple of m4 scripts that will be installed in
34	/dev/env/DJDIR/share/bison and shall not be removed.
35	It should also be noticed that the skeleton files bison.simple and
36	bison.hairy are no longer supported.  This applies also to the environ-
37	ment variables BISON_HAIRY and BISON_SIMPLE.  Those variables are *no*
38	longer honored at all.
39	The kind of skeleton file bison.hairy is no longer supported at all.
40	The skeleton file bison.simple is now called yacc.c and is an m4 script.
41	The other two skeleton files supported by this bison version are glr.c
42	and lalr1.cc.  The first one is a generalized LR C parser based on
43	Bison's LALR(1) tables and the second one is a experimental C++ parser
44	class.
45	As has been told before, bison uses m4 to generate the parser file.
46	This is done by forking and using pipes for the IPC.  MSDOS does not
47	support this functionality so this has been reproduced in the usual
48	way by redirecting stdin and stdout of bison and m4 to temporary files
49	and processing these files in sequence.  All the changes to the sources
50	are documented in the djgpp/diffs file.
51
52	Please **read** the docs.
53
54
552.:     Installing the binary package.
56	==============================
57
582.1.:   Copy the binary distribution into the top DJGPP installation directory,
59	just unzip it preserving the directory structure running *ONE* of the
60	following commands:
61	  unzip32 bsn@PACKAGE_VERSION@b.zip      or
62	  djtarx bsn@PACKAGE_VERSION@b.zip       or
63	  pkunzip -d bsn@PACKAGE_VERSION@b.zip
64
65
66
673.:     Building the binaries from sources.
68	===================================
69
703.1.:   Create a temporary directory and copy the source package into the
71	directory.  If you download the source distribution from one of the
72	DJGPP sites, just unzip it preserving the directory structure
73	running *ONE* of the following commands:
74	  unzip32 bsn@PACKAGE_VERSION@s.zip      or
75	  djtarx bsn@PACKAGE_VERSION@s.zip       or
76	  pkunzip -d bsn@PACKAGE_VERSION@s.zip
77	and proceed to the paragraph 3.3, below.
78
793.2.:   Source distributions downloaded from one of the GNU FTP sites need
80	some more work to unpack, if LFN support is not available.  If LFN is
81	available then you can extract the source files from the archive with
82	any unzip program and proceed to the paragraph 3.3, below.  Any file
83	name issue will be handled by the the DJGPP configuration files.
84	To unpack the source distribution on SFN systems, first, you MUST use
85	the `djunpack' batch file to unzip the package.  That is because some
86	file names in the official distributions need to be changed to avoid
87	problems on the various platforms supported by DJGPP.
88	`djunpack' invokes the `djtar' program (that is part of the basic DJGPP
89	development kit) to rename these files on the fly given a file with
90	name mappings; the distribution includes a file `djgpp/fnchange.lst'
91	with the necessary mappings.  So you need first to retrieve that batch
92	file, and then invoke it to unpack the distribution.  Here's how:
93
94	  djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar.gz > djunpack.bat
95	  djunpack bison-@VERSION@.tar.gz
96
97	(The name of the distribution archive and the leading directory of the
98	path to `djunpack.bat' in the distribution will be different for
99	versions of Bison other than @VERSION@.)
100
101	If the argument to `djunpack.bat' include leading directories, it MUST
102	be given with the DOS-style backslashes; Unix-style forward slashes
103	will NOT work.
104
105	If the distribution comes as a .tar.bz2 archive, and your version of
106	`djtar' doesn't support bzip2 decompression, you need to unpack it as
107	follows:
108
109	  bnzip2 bison-@VERSION@.tar.bz2
110	  djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar > djunpack.bat
111	  djunpack bison-@VERSION@.tar
112
1133.3.:   To build the binaries you will need the following binary packages:
114	  djdev203.zip (or a later but NOT a prior version)
115	  bsh204b.zip  (or a later but NOT a prior version)
116	  gcc410b.zip, gpp410b.zip, bnu2161b.zip, mak3791b.zip,
117	  fil40b.zip, shl20jb.zip, txt20b.zip,
118	  txi48b.zip, grep24b.zip, sed415b.zip,
119	  m4-144b.zip.
120
121	If you want to run the check you will need also:
122	  dif287b.zip
123
124	All this packages can be found in the v2gnu directory of any
125	ftp.delorie.com mirror.
126	You will need bsh204b.zip or later and *NOT* a prior version or
127	the build will fail.  The same applies to djdev203.zip.  Please note
128	that Bison requires m4-144b.zip or later to work properly.  All the
129	other packages are the ones I have used to build the binaries
130	from this source.  Previuos versions of this packages may do the
131	job as well but I have not tested this.
132
1333.4.:   If for some reason you want to reconfigure the package cd into the top
134	srcdir (bison-@TREE_VERSION@) and run the following commands:
135	  del djgpp\config.cache
136	  make clean
137	  djgpp\config
138
139	Please note that you *MUST* delete the config.cache file in the djgpp
140	subdir or you will not really reconfigure the sources because the
141	configuration informations will be read from the cache file instead
142	of being newly computed.
143	To build the programs in a directory other than where the sources are,
144	you must add the parameter that specifies the source directory,
145	e.g:
146	  x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
147
148	Lets assume you want to build the binaries in a directory placed on a
149	different drive (z:\build in this case) from where the sources are,
150	then you will run the following commands:
151	  z:
152	  md \build
153	  cd \build
154	  x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
155
156	The order of the options and the srcdir option does not matter.  You
157	*MUST* use forward slashes to specify the source directory.
158
159	The batch file will set same environment variables, make MSDOS specific
160	modifications to the Makefile.in's and supply all other needed options
161	to the configure script.
162
1633.5.:   To compile the package run from the top srcdir the command:
164	  make
165
1663.6.:   Now you can run the tests if you like.  From the top srcdir run the
167	command:
168	  make check
169
170	No test should fail but the tests #131 (Doxygen Public Documentation)
171	and #132 (Doxygen Private Documentation) will be skipped.  Please note
172	that the testsuite only works with LFN available.  On plain DOS, most
173	of the tests will fail due to invalid DOS names.
174
1753.7.:   To install the binaries, header, library, catalogs, and info docs
176	run the following command from the top srcdir:
177	  make install
178
179	This will install the products into your DJGPP installation tree given
180	by the default prefix "/dev/env/DJDIR".  If you prefer to install them
181	into some other directory you will have to set prefix to the appropiate
182	value:
183	  make install prefix=z:/some/other/place
184
185
186
187	Send GNU bison specific bug reports to <bug-bison@gnu.org>.
188	Send suggestions and bug reports concerning the DJGPP port to
189	comp.os.msdos.djgpp or <djgpp@delorie.com>.

192Enjoy.
