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.

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.

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.
