Qt Creator "Unable to create a debugging engine."



  • I have an iMAC:

    macOS       Catalina
    Version     10.15.7
    iMax        (Retina 5K, 27-inch, Late 2015)
    Processor   4 GHz Quad-Core Intel Core i7
    Memory      16 GB 1867 MHz DDR3
    Graphics    AMD Radeon R9 M395X 4 GB
    

    Qt Creator 4.13.1

    Based on Qt 5.15.1 (Clang 11.0 (Apple), 64 bit)
    Built on Sep 16 2020 01:17:08
    From revision 1da2c1f766
    

    Yesterday I was building, running and debugging, today my system did an system update, today I can still compile and get no warnings or errors. I can run the application, but I cannot debug the application.

    When I try to start debugging I get:

    19:08:25: Unable to create a debugging engine.
    

    Debuggers:

    Name:       System LLDB at /Applications/Xcode.app/Contents/Developer/usr/bin/lldb 
    Path:       /Applications/Xcode.app/Contents/Developer/usr/bin/lldb
    Type:       LLDB
    ABIs:       x86-darwin-generic-mach_o-64bit, arm-darwin-generic-mach_o-64bit
    Version:    1200.031.1 Apple Swift version 5.3 (swiftlang-1200.0.29.2 clang-1200.0.30.1)
    

    I suspect my problems are due to the Xcode update which was quit large.

    Is there anything I can do?



  • @SPlatten , Thank god! I ran up "Xcode" and I was presented with a dialog to install additional components which I did and now it all works again!
