Qt debugging randomly stops on Mac OSX



  • Hi,

    I am trying to debug a simple Qt application, using the serial port. The program seems to work fine, but when I try debug messages in the form of qDebug() << xxxx, then the output to the application output windows seems to stop at random times.
    Also, some breakpoints are not taken. And when I try to stop debugging, I often have to select 'abort debugging' in the debug menu.
    So it is as if QtCreator disconnects from the debugger or something.
    I have tried the same code on windows, and there everything works fine, debugging works like a charm.

    I am working on OSX El Capitan (10.11.5). I am using Qt 5.5.1 with clang6.1 64bit. QtCreator 3.5.1. I have tried an older Qt version as well, same thing.

    Any ideas anyone? Is debugging 'buggy' on Mac OSX?

    Wim

    --------Update --------
    Debugging seems to work like a charm on the new Qt5.7.0, no disconnects anymore.
    Is there an issue with lower versions on El Capitan maybe?

    Hi and welcome to devnet,

    You should also add which version of OS X, Xcode and Qt Creator you are using.
