Building XZ Utils for 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.

XZ Utils on DOS
|
||||
===============
|
||||
|
||||
DOS-specific filename handling
|
||||
|
||||
xz detects at runtime if long filename (LFN) support is
|
||||
available and will use it by default. It can be disabled by
|
||||
setting an environment variable:
|
||||
|
||||
set lfn=n
|
||||
|
||||
When xz is in LFN mode, it behaves pretty much the same as it
|
||||
does on other operating systems. Examples:
|
||||
|
||||
xz foo.tar -> foo.tar.xz
|
||||
xz -d foo.tar.xz -> foo.tar
|
||||
|
||||
xz -F lzma foo.tar -> foo.tar.lzma
|
||||
xz -d foo.tar.lzma -> foo.tar
|
||||
|
||||
When LFN support isn't available or it is disabled with LFN=n
|
||||
environment setting, xz works in short filename (SFN) mode. This
|
||||
affects filename suffix handling when compressing.
|
||||
|
||||
When compressing to the .xz format in SFN mode:
|
||||
|
||||
- Files without an extension get .xz just like on LFN systems.
|
||||
|
||||
- *.tar files become *.txz (shorthand for *.tar.xz). *.txz
|
||||
is recognized by xz on all supported operating systems.
|
||||
(Try to avoid confusing this with gzipped .txt files.)
|
||||
|
||||
- Files with 1-3 character extension have their extension modified
|
||||
so that the last character is a dash ("-"). If the extension
|
||||
is already three characters, the last character is lost. The
|
||||
resulting *.?- or *.??- filename is recognized in LFN mode, but
|
||||
it isn't recognized by xz on other operating systems.
|
||||
|
||||
Examples:
|
||||
|
||||
xz foo -> foo.xz | xz -d foo.xz -> foo
|
||||
xz foo.tar -> foo.txz | xz -d foo.txz -> foo.tar
|
||||
xz foo.c -> foo.c- | xz -d foo.c- -> foo.c
|
||||
xz read.me -> read.me- | xz -d read.me- -> read.me
|
||||
xz foo.txt -> foo.tx- | xz -d foo.tx- -> foo.tx !
|
||||
|
||||
Note that in the last example above, the third character of the
|
||||
filename extension is lost.
|
||||
|
||||
When compressing to the legacy .lzma format in SFN mode:
|
||||
|
||||
- *.tar files become *.tlz (shorthand for *.tar.lzma). *.tlz
|
||||
is recognized by xz on all supported operating systems.
|
||||
|
||||
- Other files become *.lzm. The original filename extension
|
||||
is lost. *.lzm is recognized also in LFN mode, but it is not
|
||||
recognized by xz on other operating systems.
|
||||
|
||||
Examples:
|
||||
|
||||
xz -F lzma foo -> foo.lzm | xz -d foo.lzm -> foo
|
||||
xz -F lzma foo.tar -> foo.tlz | xz -d foo.tlz -> foo.tar
|
||||
xz -F lzma foo.c -> foo.lzm | xz -d foo.lzm -> foo !
|
||||
xz -F lzma read.me -> read.lzm | xz -d read.lzm -> read !
|
||||
xz -F lzma foo.txt -> foo.lzm | xz -d foo.lzm -> foo !
|
||||
|
||||
When compressing with a custom suffix (-S .SUF, --suffix=.SUF) to
|
||||
any file format:
|
||||
|
||||
- If the suffix begins with a dot, the filename extension is
|
||||
replaced with the new suffix. The original extension is lost.
|
||||
|
||||
- If the suffix doesn't begin with a dot and the filename has no
|
||||
extension and the filename given on the command line doesn't
|
||||
have a dot at the end, the custom suffix is appended just like
|
||||
on LFN systems.
|
||||
|
||||
- If the suffix doesn't begin with a dot and the filename has
|
||||
an extension (or an extension-less filename is given with a dot
|
||||
at the end), the last 1-3 characters of the filename extension
|
||||
may get overwritten to fit the given custom suffix.
|
||||
|
||||
Examples:
|
||||
|
||||
xz -S x foo -> foox | xz -dS x foox -> foo
|
||||
xz -S x foo. -> foo.x | xz -dS x foo.x -> foo
|
||||
xz -S .x foo -> foo.x | xz -dS .x foo.x -> foo
|
||||
xz -S .x foo. -> foo.x | xz -dS .x foo.x -> foo
|
||||
xz -S x.y foo -> foox.y | xz -dS x.y foox.y -> foo
|
||||
xz -S .a foo.c -> foo.a | xz -dS .a foo.a -> foo !
|
||||
xz -S a foo.c -> foo.ca | xz -dS a foo.ca -> foo.c
|
||||
xz -S ab foo.c -> foo.cab | xz -dS ab foo.cab -> foo.c
|
||||
xz -S ab read.me -> read.mab | xz -dS ab read.mab -> read.m !
|
||||
xz -S ab foo.txt -> foo.tab | xz -dS ab foo.tab -> foo.t !
|
||||
xz -S abc foo.txt -> foo.abc | xz -dS abc foo.abc -> foo !
|
||||
|
||||
When decompressing, the suffix handling in SFN mode is the same as
|
||||
in LFN mode. The DOS-specific filenames *.lzm, *.?-, and *.??- are
|
||||
recognized also in LFN mode.
|
||||
|
||||
xz handles certain uncommon situations safely:
|
||||
|
||||
- If the generated output filename refers to the same file as
|
||||
the input file, xz detects this and refuses to compress or
|
||||
decompress the input file even if --force is used. This can
|
||||
happen when giving an overlong filename in SFN mode. E.g.
|
||||
"xz -S x foo.texinfo" would try to write to foo.tex which on
|
||||
SFN system is the same file as foo.texinfo.
|
||||
|
||||
- If the generated output filename is a special file like "con"
|
||||
or "prn", xz detects this and refuses to compress or decompress
|
||||
the input file even if --force is used.
|
||||
|
||||
|
||||
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). It works correctly under Windows 95/98/98SE/ME.
