Unable to start debugger



  • Hello,

    I have a project configured with cmake and wanted to debug this program. I found very similar topics, but didn't find any solution. I use Debian 9 64bit, Qt 5.7.1, Qt Creator 4.2.0. Previous projects with exactly the same CMakeLists.txt wored. In the meantime I was reinstalling opencv, so I suppose something wrong went there, but what? I can run program after build with make, or debug in terminal with gdb. Building debug in QtCreator succeed, but after debug try in Application output I can see:

    Debugging starts
    Debugging has failed
    Debugging has finished
    

    Debug log shows that(I post whole log):

    wNOTE: This log contains possibly confidential information about your machine, environment variables, in-memory data of the processes you are debugging, and more. It is never transferred over the internet by Qt Creator, and only stored to disk if you manually use the respective option from the context menu, or through mechanisms that are not under Qt Creator's control, for instance in swap files.

    Seeing problem with opencvtypes I found it is something in Qt Debugger - after reinstalling Qt Creator error still occurs :/ I also reinstalled python-opencv. What can I do?


  • Qt Champions 2019

    @Morales1235 said in Unable to start debugger:

    Qt Debugger

    There is no such thing, QtCreator uses GDB on Linux.

    "ImportError: No module named 'opencvtypes'\n"
    

    You need to install Python package containing opencvtypes module.



  • @jsulm said in Unable to start debugger:

    You need to install Python package containing opencvtypes module.

    Of course I supposed that, but how can I find such thing? Only place i found something about opencvtypes was QtCreator repository, directory debugger, that's why I mentioned 'Qt debugger' and reinstalled Qt Creator.

    #Edit
    I have manually downloaded opencvmodules.py and pasted into /usr/share/edbugger, where the others *.py files was.


  • Qt Champions 2019

    @Morales1235 I'm not sure which package you need to install. On my Ubuntu machine I see "python-opencv", maybe this one.

    I have a similar problem with the following error message:

    OpenCV 4.3.0 is linked to the project properly, but cannot debug. Is there a solution for this? @jsulm @Morales1235 ?


  • Qt Champions 2019

    @t3rb3d Is python-opencv installed?
    Because of this:

    &"ModuleNotFoundError: No module named 'opencvtypes'\n"
    &"Error while executing Python code.\n"



  • @jsulm Yes, sudo apt install python-opencv says it is already the newest.


  • Qt Champions 2019

    @t3rb3d Do you have more than one Python installation, like Python 2 and 3?



  • @jsulm Yes, there are more pythons:

    ls /usr/bin | grep python
    
    aarch64-linux-gnu-python2.7-config
    aarch64-linux-gnu-python3.6-config
    aarch64-linux-gnu-python3.6m-config
    aarch64-linux-gnu-python3-config
    aarch64-linux-gnu-python3m-config
    aarch64-linux-gnu-python-config
    dh_python2
    dh_python3
    python
    python2
    python2.7
    python2.7-config
    python2-config
    python3
    python3.6
    python3.6-config
    python3.6m
    python3.6m-config
    python3-config
    python3m
    python3m-config
    python-config
    

    And python-opencv is installed for the 2.7 version:

    dpkg -L python-opencv

    /.
    /usr
    /usr/lib
    /usr/lib/python2.7
    /usr/lib/python2.7/dist-packages
    /usr/lib/python2.7/dist-packages/cv2.aarch64-linux-gnu.so
    /usr/share
    /usr/share/doc
    /usr/share/doc/python-opencv
    /usr/share/doc/python-opencv/copyright
    /usr/share/lintian
    /usr/share/lintian/overrides
    /usr/share/lintian/overrides/python-opencv
    /usr/share/doc/python-opencv/changelog.Debian.gz
    

    But I also have built opencv-python from soruce:
    ls /usr/local/lib/python2.7/dist-packages/

    >> cv2
    

  • Qt Champions 2019

    @t3rb3d Try to install it for Python 3



  • It is also installed and still not working!

    dpkg -L python3-opencv

    /.
    /usr
    /usr/lib
    /usr/lib/python3
    /usr/lib/python3/dist-packages
    /usr/lib/python3/dist-packages/cv2.cpython-36m-aarch64-linux-gnu.so
    /usr/share
    /usr/share/doc
    /usr/share/doc/python3-opencv
    /usr/share/doc/python3-opencv/copyright
    /usr/share/doc/python3-opencv/changelog.Debian.gz
    

    Might it be the problem that it is an ARM cpu based system? (NVIDIA Jetson Nano)
    @jsulm do you have any idea?
