    @joseph_ho said in Project ERROR: Cannot run compiler 'g++'. Output::

    How do I run/test the MinGW 64-bit kit without running the Qt Creator?

    In a terminal. Call

    qmake.exe
    mingw32-make.exe
    

    You can open a terminal using the shortcut created during Qt installation (doing so you make sure the environment is set up properly).

    @jsulm Do you mean like this?

    I've recently switched over to Qt Creator 4.8.2 (Enterprise) but still experiencing the same problems.
    I'm starting to suspect there might be caused by some corrupted leftover files or registries.

      @joseph_ho You need to do these calls in your PROJECT directory...

          @joseph_ho Yes, but please use full paths to qmake and make.
          Also, you should use the command prompt from MinGW (you will find it in Windows start menu). You then will have ready made environment where you can call wmake/make without using full path.

              Apparently not!
              Why do you call make/qmake inside the MinGW installation directory?! We actually already clarified that.
              You need to call it inside your project/build directory (from where you called qmake).

                      @joseph_ho You should use the command prompt from MinGW installation, then the environment will be setup and ready.
