Qt under windows: Switch to a new Platform SDK

  • Our application needs to implement features that aren't available in Qt. For that I need my windows application to use win32.

    I implement my own win32 only class, and include:

    @#include <windows.h>
    #include <windowsx.h>
    #include <WinUser.h>@

    my problem is that it takes the include files from the default VS2005 location defined in the build environment setup inside Qt-Creator (VCINSTALLDIR). It is an older Platform SDK that doesn't support what I need.

    I have a newer Platform SDK at:

    @C:\Program Files\Microsoft SDKs\Windows\v6.1\include@

    How do I make Qt-Creator take the windows include files from there without the ugliness of having full paths in my source code's #include ?

    BTW: VS2005 and the new SDK are fine when built under visual Studio. No Compatibility issues whatsoever, But i'd rather stick to QT-Creator.

    I have so far tried the following without success:

    In Qt-Creator -> Projects -> build environment, I tried to modify the following items to reflect the path of the newer platform SDK first, ahead of the other paths:


  • Have you try add in your .pro file something like this:
    INCLUDEPATH += C:\Program Files\Microsoft SDKs\Windows\v6.1\include

  • when building under Qt-Creator and windows, obviously other include paths exist, that are not defined in your *.pro file. If two identically named header files exist, one in an older SDK folder and one in a new SDK folder, and QT by default takes the old one. How do you force it to use the new one? what guarantees that what's specified in the *.pro file INCLUDEPATH statements will be taken into consideration first when looking for headers or library files?
