include MinGW include in QT Creator on Windows

dalexandr

Hello,

I am using QT Creator 4.11.0 with MinGW on Windows 10 and I am trying to include header files from MinGW include path. They are visible by autocomplete but code parser complains it can't find it and compilation fails as well. Some 5 years old post I have found on the internet described the same problem and there it was solved by adding to path

D:\Qt\Tools\mingw730_64\bin
D:\Qt\5.12.0\mingw73_64\bin

In my case the path was already set and the only thing that helped me was adding include folder manually in .pro file:

INCLUDEPATH += D:/Qt/Tools/mingw730_64/lib/gcc/x86_64-w64-mingw32/7.3.0/include/

The code compiles and works fine, however now I get a warning "The code model couldn't parse included file, which might lead to incorrect code completion and highlighting" with several header files listed from the newly included folder.

The question is: is this warning an issue of Clang plugin and I am adding this include path correctly? Or should I set up MinGW in QT Creator in some different way?

What confuses me is that in the debug folder for any project I see .qmake.stash file with the following content:

QMAKE_CXX.INCDIRS = \
    D:/Qt/Tools/mingw730_64/lib/gcc/x86_64-w64-mingw32/7.3.0/include/c++ \
    D:/Qt/Tools/mingw730_64/lib/gcc/x86_64-w64-mingw32/7.3.0/include/c++/x86_64-w64-mingw32 \
    D:/Qt/Tools/mingw730_64/lib/gcc/x86_64-w64-mingw32/7.3.0/include/c++/backward \
    D:/Qt/Tools/mingw730_64/lib/gcc/x86_64-w64-mingw32/7.3.0/include \
    D:/Qt/Tools/mingw730_64/lib/gcc/x86_64-w64-mingw32/7.3.0/include-fixed \
    D:/Qt/Tools/mingw730_64/x86_64-w64-mingw32/include
QMAKE_CXX.LIBDIRS = \
    D \
    /Qt/Tools/mingw730_64/lib/gcc/x86_64-w64-mingw32/7.3.0/;D \
    /Qt/Tools/mingw730_64/lib/gcc/;D \
    /Qt/Tools/mingw730_64/x86_64-w64-mingw32/lib/;D \
    /Qt/Tools/mingw730_64/lib/;D \
    /Qt/Tools/mingw730_64/lib
.....
.....

I am only guessing, since my understanding of the processes here is not deep, but it seems the include path in question is already known.

Thanks
