|

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.

This is currently 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/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

Run "make" in this directory (the directory containing this README).

You should get xz.exe (and a bunch of temporary files). Other tools
