need help on setup of qtvcp

Hi,

I tried to follow linuxcnc.org/docs/devel/html/gui/qtvcp.html
but I already fail on section 2.2 ...

(designer starts and qtvcp -h shows help screen)

The last sentence does not match my system (debian stretch)

open a terminal, set the environment for linuxcnc . scripts/rip-environment
then load designer with : designer -qt=5

I don't have a directory named .scripts and I could not find a file called rip-enviroment all over the system.

the side you foloow is only for the Master at github to be selfcompilt

so you do not need the rip-envirewrment
as ypu installd latest stretch ypou shoudt alredy< have the QTvcp invirerment

Hm, that's only partially true.
I can start the programs, but the qt-designer does not know anything about linuxcnc.
So I need a bridge to close the gap

yes sorry the directions are incomplete...
in usr/lib/x86_64-linux-gnu/qt5/plugins/designer/python
add a link to qtvcp_plugin.py:

On a RIP linuxcnc it would be something like:
(home name and linuxcnc project name may be different for you)

/home/chris/emc-dev/lib/python/qtvcp/plugins/qtvcp_plugin.py

I'll have to look up wher it would be on an installed version...

on an installed version look in :
/usr/lib/python2.7/qtvcp/plugins/qtvcp_plugin.py

It's an educated guess - I have no installed versions of linuxcnc available to look in.

This kind of advice is better than in the tutorial.
When I know, how things should be, I can search on my own.

On my system, /usr/lib/x86_64-linux-gnu/qt5/plugins/designer contains only compiled shared libs - no directory python.

I tried both: linking qtvcp_plugin.py directly and creating a subdirectory python and put the link there ...
No change - the designer keeps on ignoring linuxcnc.

by the way - i found qtvcp_plugin.py in /usr/lib/python2.7/dist-packages/qtvcp/plugins/qtvcp_plugin.py

May be searchpath of designer is different for shared libs and python modules?

Here some more info:

When I create the python directory at usr/lib/x86_64-linux-gnu/qt5/plugins/designer and put a link to usr/lib/python2.7/dist-packages/qtvcp/plugins/qtvcp_plugin.py inside that directory, designer comes up with the messages from file logFirst.txt

... so I checked installation:
and indeed - python-pyqt5.qtsvg is not installed.
So I installed that module ...
...and now designer crashes at start with messages from logSecond.txt

Yes I pushed an update to the docs - I'm sure I'll have to update them again when we figure this out.
yes /usr/lib/x86_64-linux-gnu/qt5/plugins/designer/python is the right directory - you may have to add the python folder.

yes the link should be to /usr/lib/python2.7/dist-packages/qtvcp/plugins/qtvcp_plugin.py

next you have copied the libpyqt5_py2.so file into /usr/lib/x86_64-linux-gnu/qt5/plugins/designer ?
and is it the right version - looks like 5.7?

running from the terminal may give some error messages (if you are not already)
python.pyqt5 versions of libraries is what you need.
What distribution are you using?

SVG library _should_ not actually be necessary - just one widget is not available (but I haven't confirmed recently if it would cause a designer error - but it would give an error message in the terminal)
