Note that you could also add a symbolic link in .qgis-dev to output dir, example :


ln -s <build-dir>/output/python/plugin/* $HOME/.qgis-dev/python/plugins/

And it should load processing plugin from output dir.

No need to make recurrent copies to install dir after that.

This error means that your python files have not passed through 2to3. Make sure PORT_PLUGINS flag is turned on.

Also right now, the make script only runs 2to3 against the python code inside the output directory, it does *not* do so for the python code copied to your install location during "make install". You either can run QGIS from your output directory, or (as a temporary ugly hack) copy the content of the python folder in your output directory onto your installation's /share/qgis/python directory.

Hope that helps.

    Hi,

    testing Python3/Qt5 I get the following message:

      File
    
"/home/richard/apps/qgis3/master/debug/share/qgis/python/plugins/processing/tools/vector.py",
    line 34, in
        import cStringIO

    According to:

    http://stackoverflow.com/questions/30377620/python-3-4-cstringio-vs-stringio
    
<http://stackoverflow.com/questions/30377620/python-3-4-cstringio-vs-stringio>

    there is no cStringIO anymore in py3

    do I miss a compile/install step or isn't processing not yet ready to
    use yet?

    Regards,

    Richard Duivenvoorde
