This document explains how to build XZ Utils for DOS using DJGPP.
The resulting binaries should run at least on various DOS versions
and under Windows 95/98/98SE/ME, although the Windows version of
XZ Utils is recommended under Windows 95 and later.
and under Windows 95/98/98SE/ME.
This is currently experimental and has got very little testing.
This is somewhat experimental and has got very little testing.
Note: Makefile and config.h are updated only now and then. This
means that especially if you checked out a development version,
building for DOS probably won't work without updating Makefile
and config.h first.

Getting and Installing DJGPP
You may use <http://www.delorie.com/djgpp/zip-picker.html> to help
deciding what to download, but as of writing (2010-10-09) that may
not be the most convenient way taking into account what components
are actually required to build XZ Utils. However, using the
zip-picker can still be worth doing to get nice short summary of
installation instructions (they can be found from readme.1st too).
deciding what to download. If you are only interested in building
XZ Utils, the zip-picker may list files that you don't strictly
need. However, using the zip-picker can still be worth it to get a
nice short summary of installation instructions (they can be found
from readme.1st too).
For a more manual method, first select a mirror from
<http://www.delorie.com/djgpp/getting.html>. You need
the following files:
<http://www.delorie.com/djgpp/getting.html> and go the
subdirectory named "current". You need the following files:
unzip32.exe (if you don't already have a LFN-capable unzipper)
beta/v2/djdev204.zip
v2gnu/bnu219b.zip
v2gnu/gcc444b.zip
v2gnu/mak3791b.zip
v2/djdev205.zip
v2gnu/bnu234b.zip
v2gnu/gcc920b.zip
v2gnu/mak43b.zip
v2misc/csdpmi7b.zip
If newer versions are available, probably you should try them first.
Note that djdev203.zip is too old to build XZ Utils; you need at
least djdev204.zip. Also note that you want csdpmi7b.zip even if you
run under Windows or DOSEMU, because the XZ Utils Makefile will embed
cwsdstub.exe to the resulting binaries.
Note that versions older than djdev205.zip aren't supported. Also
note that you want csdpmi7b.zip even if you run under Windows or
DOSEMU because the XZ Utils Makefile will embed cwsdstub.exe to
the resulting xz.exe.

Once you have built XZ Utils, the resulting binaries can be run
without long filename support.
Run "make" in this directory (the directory containing this README).
You should get xz.exe (and a bunch of temporary files). Other tools
are not built. Having e.g. xzdec.exe doesn't save much space compared
to xz.exe, because the DJGPP runtime makes the .exe quite big anyway.
