    @Thembalami-Msimango

    Look in task manager when you compile

    alt text

    Is all your cores fully used?

        @Thembalami-Msimango Right click on the graph and select "Logical processors" (or whatever the english text is).

          @Thembalami-Msimango Go to Project settings ->Build -> Build steps and check what is set in "Parallel jobs" (it should be the number of logical cores of your CPU).

              There is, you need to expand "Details".
              But you can already see "-j4" which means 4 build processes are used, so looks good.

                @jsulm Eish ohk I see, I guess I will have to switch to a different IDE since this one seems to have problems beyond reach, thank you

                  @Thembalami-Msimango The IDE is most probably not the problem here. QtCreator simply calls qmake and then make. You could try to build manually in a terminal to see whether it is also slow or not.

                      If the course instructor is using Ubuntu, then (despite the overhead of installing extra tools), you might find it simplest to:

                      • install VirtualBox
                      • create an Ubuntu VM
                      • use qmake in a terminal window inside your Ubuntu VM

                      Hopefully in this way you can eliminate any discrepancy between the instructor's procedure and your own, and maximize chances of success (with success being defined here as "replicating whatever the instructor is doing without errors").

                      I would also recommend matching the exact Ubuntu version preferred by the instructor, and the exact Qt version.

                        I should have also mentioned, for completeness: I 100% agree with @jsulm 's hypothesis that "The IDE is most probably not the problem here"

                        However, the set of possibilities that contains the actual problem could still be a very large set (possibly unbounded?).

                        Therefore, if you are under a deadline for coursework, that is why I recommend just sticking verbatim to whatever the instructor is doing.
