    Default Debugging extremely slow

    Stepping through the code while debugging under QT Creator is extremely slow on my computer, to the point of being unusable. This behaviour appeared when I upgraded to QT Creator 2.0.

    Does anyone has an idea on how to fix this problem ?

    Thanks.

    Default Re: Debugging extremely slow

    I reverted to version 2010.02.1 where the problem is definitively not present, with the exact same sources.

    I tried to remove a lot of sources from the project ( which consists of several dlls ), and I had the feeling that the more code I removed, the faster the 'step in' or 'step over' became.

    Has anyone encountered a similar issue ?

    Thanks.

    Yes, I am experiencing the same thing using version 2.0.90. If you shut down QTCreator and restart it, it works ok for the first few debugging breakpoints, but then becomes slow.

    Me too, in 2015


    Added after 1 2 minutes:


    It's fine, as long as I don't use the expression evaluator. Using ots of qDebug() instead. I can add a qDebug statement build, and restart the app faster than a single step. (Single step takes more than 30 seconds).
