Hi, I should explain clearer. "w64" in the vendor key does not actually mean win64 only. It means that mingw-w64 headers are used instead of mingw.org equivalents. It will activate stuff like "-municode" in GCC. If its not "w64", GCC will assume that mingw.org header set and libs are used instead of mingw-w64 provided equivalents. It will disable features specific to mingw-w64, so its more mingw.org compatible. Like NightStrike suggested, you should use "w64" if you are using mingw-w64 provided headers. "w32" will have the same effect as using "pc" as vendor key. Was it clear? Sorry for the confusion. ------------------------------------------------------------------------------ Come build with us!
