    @jsulm "Tools/Options.../Build & Run/Kits" looks fine. Screenshot: (http://imgur.com/PejHdgW)
    This forum's "insert image" widget does not seem to work with imgur.

    From your screenshot it's apparent you have no c++ compiler.

      To add to my fellows who already noted it and since you are on Linux, you need to install g++ as well.

      Note that I find it surprising that it's not already the case since you seem to have your distribution installed Qt development environment.

        OK, we're making progress. g++ was missing, installed it and the qmake error went away. Now when I try to build an example it complains about GL/gl.h missing.

        I have some OpenGL stuff installed, my old OpenGL program compiles and runs, so I am at a loss here as to what is needed.

        I could have sworn that in my last go-round with Linux the c++ compiler was installed by default, and may even have been the same as the C compiler.

          @bogwon C++ compiler is not the same as C compiler. GNU Compiler Collection (GCC) is a collection of different compilers, one of them is C++, it is called g++.
          Regarding the error: install mesa-common-dev and libgl1-mesa-dev packages

                  @jsulm C & c++ compilers are different animals now, but I am pretty sure that not too long ago there was one compiler that did both. Albeit, 'not too long ago' might mean ten or 20 years.

                        HI
                        Did you install the Qt visual 2015 packet ?

                        Also, did you go download the actual visual studio compiler from microsoft site ?

                        It must match. Qt version and Visual studio version

                        So it wont work if u installed say vs 2013 or vs 2017

                            Hi
                            Not sure what that is.
                            Make sure you check on C++ in VS installer. Its not on pr default.
                            Also no debugger pr default . must also be installed.
                            the b4 bit version
                            and make sure the Qt version macth your compiler.

                            If all fails and you really just wanted to use Qt and not have to use Visual Studio
                            then try
                            https://download.qt.io/archive/qt/5.8/5.8.0/qt-opensource-windows-x86-mingw530-5.8.0.exe
                            It has compiler and debugger with :)
