Hi all, I have managed to compile GRX under Cygwin with gcc -mno-cygwin (this is essentially just using MinGW and MinGW-Runtime). gcc is version 3.2, just for the record. After some minor changes, it also compiles and links without warnings as a native cygwin application. It just doesn't run and hangs somewhere in GrSetMode(). Can anybody enlighten me what is missing to complete the port to native Cygwin? TIA, Ciao Tom Thomas Demmer Kraft Foods R&D Munich Phone: +49 89 62738-6302 Fax: +49 89 62738-86302 Thought of the Day: A little inaccuracy saves a world of explanation. -- C.E. Ayres
