    I switched from MacOS Mojave to Arch Linux x86_64 today and I have installed ALL of the packages required for Qt and Qt Creator. When I create a new project and run it there is no issue. When I open my project that I created on MacOS there is NO error in any .cpp or .h file but whenever I try to build and run the project I get exited with code 255 in my application output. There are no issues nor warnings with my code. Why might my code not run properly?

    Also I tried creating a new Qt desktop application and pasting code from the original project to my "new" project. I edited practically everything but the .pro file and I get 0 errors when I try to build but I still can't run the program without the exited with code 255 error.

    Compile output

    13:16:27: Running steps for project PerfectNote...
    13:16:27: Configuration unchanged, skipping qmake step.
    13:16:28: Starting: "/usr/bin/make" -j4
    make: Nothing to be done for 'first'.
    13:16:28: The process "/usr/bin/make" exited normally.

    Edit: I added qDebug() << "here"; at the top of my file but could not see it in application ouput or anywhere else. However when I enter the build-myApp-debug folder and run ./myApp I get the correct output from qDebug()! Anybody got any idea why the output in Qt Creator does not work?

      Hi,

      Did you get any warning when compiling ?
      Do you have gdb installed ?
