I successfully built Crystal Space after many hours of trying.
Then I realized that i'd forgotten to install the java bindings, so I couldn't use CS in java applications.
Now I've spent 5 hours of making a new CS directory, reinstalling mingw, msys and crystalspacelibs for windows, and installed Swig and Ant.
After I had finally managed to rebuild Crystal space I noticed that I didn't get any jar file as the manual says.
What am I doing wrong?
Crystal Space 1.2rc1
MinGW-5.1.3 Full installation
CS-win32libs-1.1_001 Full installation
