Hello, I downloaded Qt and installed it into its default location on mac os x, then tried to initialize it with: using qt5 : /users//Qt/5.3/clang_64 ; I don't know if the above is the correct way to initialize the qt5 support, but I get bad include directories, e.g. #include won't work. Searching the Qt directories reveals that the file QWindow is found under Qt/5.3/clang_64/lib/QtGui.framework/Versions/5/Headers. So what is the right way to do this? -- Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
