This says you have libpyqt5_py2.so in the right place but it doesn't tell me what version (they are all named the same)
I has to be the same version of QT on the system, which I believe for you is 5.7

When you compare the sizes (and timestamp) you see the match

I see he sets the path for the library with:
export PYQTDESIGNERPATH='/path/to/plugin/directory/'

I tried that like this
export PYQTDESIGNERPATH='/usr/lib/python2.7/dist-packages/qtvcp/plugins'
... and designer crashes again

you could go to the qtvcp_plugin.py script and comment out:

#from qtvcp.plugins.widgets_plugin import *

#from qtvcp.plugins.dialog_plugin import *

Then you shouldn't need the svg library (you'll be missing lots of widgets)

I tried to follow the tutorial on the fresh virtualbox installation ...
designer starts without linuxcnc widgets, but shows the plugin as loaded (empty).

Konsole logs different errors on startup of designer:
designer -qt=5
Error while reparenting!
Designer: Bei der Erzeugung von Widgets wurden widersprüchliche Klassennamen festgestellt: Die Factory für benutzerdefinierte Widgets der Klasse KDialog gab ein Widget der Klasse QDialog zurück.
QMetaProperty::read: Unable to handle unregistered datatype 'SelectionBehavior' for property 'QTabBar::selectionBehaviorOnRemove'

Next I gonna try a mint installation ...

while waiting for completion of mint-iso download, I tried the linked tut of Kurt from github.
I could follow the instructions until building of PyQt5, which failed (on a fresh debian install from virtualbox) with

I know compiling it was often a pain - thats why I added the precompiled versions to linuxcnc.

I am sorry you are having so much trouble - I don't know why.
I have this working with debian and mint - but always RIP - I don't see why that matters :(

Unfortunately I am off to work for 2 weeks so can't offer much more help.

I have this working with debian and mint - but always RIP - I don't see why that matters

Well, the python development environments (configure.py i.e.) destroys debian security.
When you look at old stuff packages with configure shell scripts, they always use a prefix parameter, which defaults to /usr/local - that way you can compile and test a package without any harm on your productive system (paths to /usr/local have preceedance to /usr and using a separate filesystem at /usr/local allows to switch off any testing stuff with a single reboot)

Therefore I tested installation with a virtualbox, where I saved a snapshot after system installation.
I followed Quick Start Tutorial, which leaded to the already well known situation: designer without linuxcnc widgets and/or crashing designer or crashing linuxcnc

Then I tried Development Install .
I have to confess, that I don't really understand, what are sequential steps and what are alternatives ...
First I thought, that "Installing from Debian package" might be an alternative - but performing this, nothing at all works. No sip, no qtpyvcp, no widgets in designer ...

So I tried the Development Install Instructions after the package installation ...
... and got the same result as before ...

Don't know, what am I doing wrong.

As all different installation variants lead to the same result, I thought: may be it works anyway?
... and stepped over to Getting Started
First steps look promising, but when I try to edit template (editvcp ...), it tells, what the designer already showed:
Traceback (most recent call last):
  File "/home/cncob/.local/bin/editvcp", line 11, in <module>
    load_entry_point('qtpyvcp', 'console_scripts', 'editvcp')()
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 561, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2631, in load_entry_point
    return ep.load()
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2291, in load
    return self.resolve()
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 2297, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)

    from qtpy.QtWidgets import QApplication, QFileDialog

    raise PythonQtError('No Qt bindings could be found')
qtpy.PythonQtError: No Qt bindings could be found
Last line seems the most important one ...

I checked my system: Yes, its a 64bit debian and qt-designer is of version 5.7.1
I gave up the idea to try a mint installation. Download breaks too often and after all - its no system, I want to use ...

I run out of ideas :(

This has to be because you are using an installed version - it works fine in multiple computers and systems and people as RIP.

I'm sorry you are having these problems - when i get home i will do an instal version of linuxcnc and see if I can duplicate the problem.

Hi Chris,

thanks a lot for your attention and support!
I very appreciate that you take the time for stil answering!

I searched a lot and I came up in reading docs for the qt-designer - but then I had to stop myself. That's nothing I wonna do. So may be qt is not the right tool for me.

I tried a few steps with glade and after building an old gui-builder I already have the linuxcnc controls in the builder. At the moment I don't understand anything, but may be, that path is more appropriate for me.
At least I don't have trouble with the tools there.
And at the moment I don't care for stylish look - just wonna get something to work with ;)

Cheers Reinhard
