XZ Utils on DOS
|
|
===============
|
|
|
|
Introduction
|
|
|
|
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).
|
|
|
|
For a more manual method, first select a mirror from
|
|
<http://www.delorie.com/djgpp/getting.html>. 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
|
|
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.
|
|
|
|
See the instructions in readme.1st found from djdev204.zip. Here's
|
|
a short summary, but you should still read readme.1st.
|
|
|
|
C:\> mkdir DJGPP
|
|
C:\> cd DJGPP
|
|
C:\DJGPP> c:\download\unzip32 c:\download\djdev204.zip
|
|
C:\DJGPP> c:\download\unzip32 c:\download\bnu219b.zip
|
|
C:\DJGPP> c:\download\unzip32 c:\download\gcc444b.zip
|
|
C:\DJGPP> c:\download\unzip32 c:\download\mak3791b.zip
|
|
C:\DJGPP> c:\download\unzip32 c:\download\csdpmi7b.zip
|
|
|
|
C:\DJGPP> set PATH=C:\DJGPP\BIN;%PATH%
|
|
C:\DJGPP> set DJGPP=C:\DJGPP\DJGPP.ENV
|
|
|
|
You may want to add the last two lines into AUTOEXEC.BAT or have,
|
|
for example, DJGPP.BAT which you can run before using DJGPP.
|
|
|
|
Make sure you use completely upper case path in the DJGPP environment
|
|
variable. This is not required by DJGPP, but the XZ Utils Makefile is
|
|
a bit stupid and expects that everything in DJGPP environment variable
|
|
is uppercase.
|
|
|
|
|
|
Building
|
|
|
|
You need to have an environment that supports long filenames (LFN).
|
|
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.
|
|
|
|
|
|
Bugs
|
|
|
|
xz doesn't necessarily work in Dosbox. It should work in DOSEMU.
|
|
|
|
Pressing Ctrl-c or Ctrl-Break won't remove the incomplete target file
|
|
when running under Windows XP Command Prompt (something goes wrong
|
|
with SIGINT handling). Use the Windows build of XZ Utils on Windows.
