[QGIS-Developer] Voronoi tool missing from processing, what could be wrong?

[Hernán De Angelis-5]

Hi,

I wrote about this a few days ago in the user list but I still have the
problem and can find neither a cause nor a solution. I thus post it in
this list in the hope that some developer may have a hint on what is
going wrong here.

In my installation the Voronoi Polygon tool is missing from the
Processing menu, both from the bar (vector geometry dialog) and the
processing panel. It is also not listed in the Python console (see below
whole listing).

But, the code seems to be present in the /usr/local/share... folder,
where other plugins live as well:

localhost:/usr/local # find ./share -name *oronoi*
./share/qgis/python/plugins/processing/algs/grass7/description/v.voronoi.skeleton.txt
./share/qgis/python/plugins/processing/algs/grass7/description/v.voronoi.txt
./share/qgis/python/plugins/processing/algs/grass7/ext/v_voronoi.py
./share/qgis/python/plugins/processing/algs/qgis/VoronoiPolygons.py
./share/qgis/python/plugins/processing/algs/qgis/voronoi.py

I compile QGIS from source, things have gone smoothly every time and I
cannot see any obvious particular problem. I have tested with master a
couple of weeks ago, then 3.18.0 a couple of days ago, and moments ago
with 3.16.4 (after wiping all traces of previous installations) but the
problem persists.

Anyone has seen this? What could possibly be wrong here?

Thanks in advance,

Hernán

Might seem obvious, but have you tried using a brand new profile?

With me your find-output looks exactly the same

With me your python code shows voronoi in the 'qgis' group instead of the 'native' one:

qgis:voronoipolygons -> Voronoi polygons

I do have like 58 algorithms in the 'qgis' group. Are you missing all qgis ones? Or just voronoi?

And in processing it just shows up with me (see screenie)

Some things to check:

-1- is the /usr/local/share/qgis/python/plugins/ dir in your PYTHONPATH ?

With me (installed QGIS in /home/richard/bin/qgis_/3.18/debug) these to are in my PYTHONPATH:
/home/richard/bin/qgis_/3.18/debug/share/qgis/python
/home/richard/bin/qgis_/3.18/debug/share/qgis/python/plugins

import sys
print(sys.path)

or is there other 'cruft' in it?

-2- is your LD_LIBRARY_PATH ok? To me (installing in my homedir), I have to add the debug/lib dir to my LD_LIBRARY_PATH.
adding:
export LD_LIBRARY_PATH=~/bin/qgis_/3.18/debug/lib/:/usr/lib/grass78/lib/
to my startup of qgis 3.18

I think if you install in default locations (like you do) then this should not be a problem, but maybe the QGIS python code can not load the right c++-libs?

Richard Duivenvoorde

Double check that you have the gdal python packages installed

Thanks for this,

from osgeo import gdal

just works, so I guess it is installed.

What is the value of
BINDINGS_GLOBAL_INSTALL
in your compile config?

Looks like something is not picked up with your install.

What if you run qgis 31.8 from the 'output/bin' dir in your build directory?

If all fails I would (I think) compile and set CMAKE_INSTALL_PREFIX in some local dir in your HOME

I did in ~/bin/qgis_/3.18/debug (for debug build):

And create a startup script like

export LD_LIBRARY_PATH=~/bin/qgis_/3.18/debug/lib/:/usr/lib/grass78/lib/
export PYTHONPATH=~/bin/qgis_/3.18/debug/share/qgis/python:$PYTHONPATH
export QGIS_DEBUG=0
# passing ALL parameters to qgis bin
# eg to be able to call a certain translation
# qgis --lang nl
~/bin/qgis_/3.18/debug/bin/qgis "$@"

Suc6

Thanks you Richard, but that did not work either.

Thanks Alexander and Nyall too.


This is happening in a fresh install (one month old) of openSUSE
Tumbleweed in a new machine. No older profiles to blame here. Also I did
delete the profiles many times.

No clue by now, will have to keep looking.

Thanks again everyone

Hernán

Thanks, will think about this and try it.

Thank you again for your ansers. I see I have a sort of linking/library
problem. GRASS is installed and GRASS modules are compiled but then
these do not appear either in the menu.

Hi

Can you check if you have python-psycopg2 installed on your system? I had a similar issue a month or two back which was fixed by installing it. (Thanks for the nudge Nyall).

Regards

Tim

Ah -- that was the one!  I thought it was gdal for some reason...
flaky memory :)

We should really investigate why this caused a silent failure to show
the algorithms instead of an error...

Hi

I made this so my previous noodling around to fix the issue are captured somewhere:

https://github.com/qgis/QGIS/issues/41984

I guess QgsRuntimeProfiler.profile is just sweeping the exceptions under the rug rather than letting them surface?

Ah -- that was the one!  I thought it was gdal for some reason...
flaky memory :)

We should really investigate why this caused a silent failure to show
the algorithms instead of an error...

Hi

Can you check if you have python-psycopg2 installed on your system? I had a similar issue a month or two back which was fixed by installing it. (Thanks for the nudge Nyall).

YES! That was the problem!

Now I have all the tools, including GRASS and GDAL, and Voronoi of course.

Thank you!

Thanks, will think about this and try it.

Thank you again for your ansers. I see I have a sort of linking/library
problem. GRASS is installed and GRASS modules are compiled but then
these do not appear either in the menu.

Yes, an error message could be beneficial. I remember from previous
installations that QGIS would complain on opening that psycopg (or other
python modules) weren't installed.
