+
+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, which cannot run the Windows version
+ of XZ Utils.
+
+ This is currently experimental and has got very little testing.
+
+
+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 (2009-02-13) 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 more manual method, first select a mirror from
+ <http://www.delorie.com/djgpp/getting.html>. You need
+ the following files:
+
+ unzip32.exe
+ beta/v2/djdev204.zip
+ v2gnu/bnu219b.zip
+ v2gnu/gcc432b.zip
+ v2gnu/mak3791b.zip
+ v2gnu/sed415b.zip
+ v2misc/csdpmi5b.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 csdpmi5b.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\gcc432b.zip
+ C:\DJGPP> c:\download\unzip32 c:\download\mak3791b.zip
+ C:\DJGPP> c:\download\unzip32 c:\download\sed415b.zip
+ C:\DJGPP> c:\download\unzip32 c:\download\csdpmi5b.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
+
+ Just run "make" in this directory (the directory containing this
+ README). You should get liblzma.a, xz.exe, xzdec.exe, and
+ lzmadec.exe. Of these, probably xz.exe is the only interesting one.
+
+ Note: You need to have an environment that supports long filenames.
+ Once you have built XZ Utils, the resulting binaries can be run
+ without long filename support.
+
+
+Additional Make Flags and Targets
+
+ You may want to try some additional optimizations, which may or
+ may not make the code faster (and may or may not hit possible
+ compiler bugs more easily):
+
+ make CFLAGS="-O3 -fomit-frame-pointer -funroll-loops"
+
+ If you want to enable assertions (the assert() macro), use DEBUG=1.
+ You may want to disable optimizations too if you plan to actually
+ debug the code. Never use DEBUG=1 for production builds!
+
+ make DEBUG=1 CFLAGS="-g -O0"
+
+
+Bugs
+
+ "make clean" may remove src/xz/hardware.c when it tries to remove
+ src/xz/hardware-fixed.c. This is probably a bug somewhere in the
+ DOS environment I use. Maybe it tries truncated 8.3 name first and
+ since that gives a name of an existing file, it doesn't look for
+ long filename.
+
+ "xz -fc /dev/tty" hangs at least in DOSEMU and cannot be interrupted
+ by pressing C-c. Maybe xz should never accept non-regular files on
+ DOS even when --force is used.
+
+ Using different memory usage limit for encoding and decoding doesn't
+ make sense under pure DOS. Maybe it is still OK when running under
+ Windows.
+
+ The progress indicator of "xz -v" doesn't get updated when running
+ under Dosbox, but it works in DOSEMU. I currently (2009-02-13) don't
+ know if it works in other environments.
+
+ Report bugs to <lasse.collin@tukaani.org> (in English or Finnish).
