Qt Creator debugging not starting...

  • Hello Everybody,
    i am trying to debug a simple test window application with qt. The applicatino successfully compiles, but when i try to debug, the debugger will not start, and in general messages windows i have "Running Windows Runtime device detection.
    No winrtrunner.exe found." that's all, debugging windows says : debugging starts... debugging has finished. " and in the right corner it 's written lauching debugger with a red bar.
    I use Qt 5.12.2 installed with online installer, for windows 10. I have installed only following components.

    • Qt 5.12.2 with mingw 7.3.0 32 bit.
    • Qt Creator 4.8.2 CDB Debugger support
    • MinGW 7.3.0 32-bit.

    Under "Manage Kits" options, it's seems that paths are correctly set.
    Should i install some other kit? some other thing to let it work?

    Many thanks.

    Might a silly question but since:

    @emazed said in Qt Creator debugging not starting...:

    No winrtrunner.exe found

    Are you sure you are using the right kit ?

  • @SGaist i checked your answer, and saw that message about winrtrunner.exe was not related to launching debugger. I am sorry. Copying in the directory of the executable the libraries that it needs, will solve. Thank you for hint

  • @emazed I am happy that you resolved the issue.

    I had a similar issue, but without the No winrtrunner.exe found error.

    Debugging starts, Debugging has finished

    I was able to track down the issue with the help of Qt Creators' Global Debugger Log window. I found that GDB was loading DLLs from my Git for Windows installation.

    GDB issue

    Upon further investigation, I found out that I had the C:\Program Files\Git\mingw64\bin path in my Windows System PATH. Removing this path and restarting Qt Creator (or maybe even Windows itself) should solve the issue.
