This + means that if you checked out a development version, building for + DOS might not 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. 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> and go the + subdirectory named "current". You need the following files: + + unzip32.exe (if you don't already have a LFN-capable unzipper) + 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 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. + + See the instructions in readme.1st found from djdev205.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\djdev205.zip + C:\DJGPP> c:\download\unzip32 c:\download\bnu234b.zip + C:\DJGPP> c:\download\unzip32 c:\download\gcc920b.zip + C:\DJGPP> c:\download\unzip32 c:\download\mak43b.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 + INSTALL.txt). 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. + diff --git a/dos/Makefile b/dos/Makefile new file mode 100644 index

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.
