To build Tintware on Win32 you will need Visual C++ 6.0 and zlib. Install zlib in a directory at the same level as tintware. From the directory zlib, run nmake -f win32\makefile.msc. From the directory tintware\win32, run nmake clean and then nmake install. This will build everything.
To build Tintware on Mac OS X you will need Apple's Developer Tools. From the directory tintware/macosx, run make clean and then make install. This will build everything.
To build Tintware on Unix (Darwin and Linux), from the directory tintware/unix, run make clean and then make install. This will build everything into debug and release. Copy temacs (and tci and tintc if you want them) to some place on your path. Put txml.dylib some place on your DYLD_LIBRARY_PATH or LD_LIBRARY_PATH.
