INCLUDEPATH not honored when compiling using MSVC2013

  • I downloaded and installed qt-opensource-windows-x86-msvc2013-5.5.1.exe.
    With MSVC2013 I created a library that comes with its own include files.
    For the sake of simplicity, I put the include file in C:\temp.
    I also added INCLUDEPATH += C:/temp to the .pro file
    However, when I try to compile, there is an error that the compiler cannot file this file:

    C:\Users\rpamm\songbase\app\SBMediaPlayer.cpp:5: error: C1083: Cannot open include file: 'portaudio.h': No such file or directory

    Looking at the compiler output, I don't see any reference to the INCLUDEPATH (added to the .pro file). Following is the output at it appears in the 'Compile Ouput' tab:

    	C:\Qt\Qt5.5.1\Tools\QtCreator\bin\jom.exe -f Makefile.Release

    Am I missing something?

    Thanks for any help/hints/directions.

    Is portaudio.h located in C:/temp or in a subfolder ?

  • @SGaist Just located in c:\temp

    Did you re-run qmake after modifying the .pro file ?

  • You're the man! That did the trick.
    I still don't see the include path displayed in the compiler output tab, not sure why.

    Thanks again for helping me out.
