I posted about wxwindows before- I am looking at wxpython right now to learn a bit about cross platform GUI. Here is the link for setting up a compiler to create win32 binaries on linux. Got this from the wxwindows site. Perhaps it will help someone- but is is over my head. The wxwindows libraries are based on GTK (wxGTK) for 'nix and so I though it might be useful somehow for Crossfire (GTK, motif, windows, python...macOS on the way). http://www.wxwindows.org/technote/crosscmp.htm -tm
