Permission denied

  • How do I get a permission denied when I'm running as an administrator?

    @c:/qt/tools/mingw48_32/bin/../lib/gcc/i686-w64-mingw32/4.8.0/../../../../i686-w64-mingw32/bin/ld.exe: cannot open output file debug\helloWorld-widget.exe: Permission denied
    collect2.exe: error: ld returned 1 exit status
    Makefile.Debug:78: recipe for target 'debug\helloWorld-widget.exe' failed
    mingw32-make[1]: *** [debug\helloWorld-widget.exe] Error 1@

    I guess your program is running already. Close it before starting another run.

  • The strange thing is that I don't see my program that's already running. I see it and close it the first two times but then when I run it a third time I get this error.

    is it a console application?

    It might be running, but invisible. Open your task manager (Ctrl+Shift+Esc) and check the list of running applications/processes.

    How did you quit your program before?

  • I have the same problem, and I have seen this on older Qt versions as well. Installed Qt5 today.

    What I observe is that once you compile and go you get this problem if you re-compile afterwards. If I wait a bit it seems that the problem resolves itself. This remind me of a a known Windows issue that the OS can hold on to files for some time. This is however not an issue with Code::Blocks or other IDE's using WinGW.

    This was on a QtWidget app, I have tried different ways of stopping the application. I can never see it running in Task Manager and the only way to get around it by starting/stopping QtCreator or simply wait.

  • I have the same problem I'll go crazy !
    My application quit with code 0.
    But now I can compile only one time !
    I passed my program to my colleague and he has no problem.
    I use Qt 3.0.0 with Framework 5.2.0 MinGW 4.3
    This problem appears with no reason... I'm desesperate
