Qt 5.2.0 MSVC2012 stddef.h missing
first of all excuse my poor english and I am a Qt newbie :)
I want to create a Editor for a small Engine with Qt but i have several problems.
My Engine is working with DirectX 11.0 but MinGW 4.8 is unable to compile the project because of hundrets syntax errors in d3dx11.h (?), but i can compile and build the engine in VS2012. When i try to build the project in Qt Creator with MSVC2012 i've got that error:
C:\Programming\Qt\5.2.0\msvc2012\include\QtCore\qglobal.h:46: Error: C1083: Cannot open include file: 'stddef.h': No such file or directory <<
How i can fix one of my problems?
