This is a port of GNU Bison @VERSION@ to MSDOS/DJGPP.
|
||||
|
||||
|
||||
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
|
||||
|
||||
|
||||
|
||||
3.: Building the binaries from sources.
|
||||
===================================
|
||||
|
||||
3.1.: 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,
|
||||
m4-143b.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 m4-143b.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.
|
||||
|
||||
3.2.: Create a temporary directory and copy the source package into the
|
||||
directory. If you download the source distribution from one of the
|
||||
DJGPP archives, 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
|
||||
|
||||
3.3.: 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.
|
||||
|
||||
|
||||
3.4.: To compile the package run from the top srcdir the command:
|
||||
make
|
||||
|
||||
3.5.: Now you can run the tests if you like. From the top srcdir run the
|
||||
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.
|
||||
|
||||
3.6.: 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
|
||||

||||

||||
