I'm a bit worried by the Windows version: - liblzma can't be compiled by Visual Studio: too many C99 isms, mostly variables declared in the middle of a block. It's doable for sure, but it's a lot of work. - liblzma is normally compiled with mingw, but we have to be sure that is uses the correct MSCRT C runtime, and what about debug builds? - All extension modules use static libraries: zlib, expat, sqlite. But a gcc static library can't be used by Visual Studio. - The way recommended by XZ is to use a precompiled liblzma.dll; Then it should be easy to build an extension module, but its would be the first time that we distribute an extension module which needs a non-system DLL. Is it enough to copy it next to _lzma.pyd? Is there some work to do in the installer? Too many "but"s :)
