linux version: libTopologicCore.so.0 file too short + other problems about topologicsverchok HOT 12 CLOSED

If it continues to give the same error, I think I know why. The following link seems wrong:
/home/arun/.config/blender/3.2/scripts/addons/topologicsverchok/site-packages/topologic/./libTopologicCore.so.0
There shouldn't be a /./ between topologic and libTopologicCore.so.0

from topologicsverchok.

Thank you for flagging this. I will look at the build tool chain soon and fix it

from topologicsverchok.

@sanzoghenzo I have updated the linux release. Please test and let me know if this is now resolved. Thank you for spotting it.

Hi, thanks for the quick update!

Unfortunately, it still doesn't work for me, but I realized it's not your fault.
the files at the left are from your zip file, those at the right are in the blender addon folder.

I suppose blender's add-on installer doesn't like symlinks...

after fixing the symlinks it still complains about missing libTKernel.so.7, and indeed there's no such file:

from topologicsverchok.

Oh that is disappointing. OK, I have removed all the symlinks and uploaded a new -B release in the same place. It works perfectly well on my Ubuntu Groovy Gorilla Linux. So, not sure what the problem is. There shouldn't be a libTKernel.so.7 It should either be 7.7 or 7.7.0. In any case, I removed all the .7.7 and .7.7.0 files and left only .so files and it seems to be working fine. Thank you for your patience. I hope it works, but if not, please reply here and I will try to debug some more.

Found out I still had a glitch finding the libTopologicCore.so.0 file. I fixed that (hopefully) with the patchelf command. I uploaded a "-C" version to the release. Hopefully that solves it. Please let me know.

from topologicsverchok.

Just tried the "-D" version, the libTopologicCore problem is gone, but unfortunately I still have the libTKernel.so.7 problem.
Not only that, I tried to make a symlink of that file and repeat for every file it told me... here's the list:

ln -s libTKernel.so libTKernel.so.7
ln -s libTKMath.so libTKMath.so.7
ln -s libTKOffset.so libTKOffset.so.7
ln -s libTKPrim.so libTKPrim.so.7
ln -s libTKMesh.so libTKMesh.so.7
ln -s libTKBO.so libTKBO.so.7
ln -s libTKShHealing.so libTKShHealing.so.7
ln -s libTKG3d.so libTKG3d.so.7
ln -s libTKG2d.so libTKG2d.so.7
ln -s libTKGeomBase.so libTKGeomBase.so.7
ln -s libTKGeomAlgo.so libTKGeomAlgo.so.7
ln -s libTKTopAlgo.so libTKTopAlgo.so.7
ln -s libTKFillet.so libTKFillet.so.7.7
ln -s libTKBool.so libTKBool.so.7.7
ln -s libTKBRep.so libTKBRep.so.7.7

At this point I got another error:

Traceback (most recent call last):
  File "/usr/share/blender/3.1/scripts/modules/addon_utils.py", line 351, in enable
    mod = __import__(module_name)

I have no idea of what's going on here!

from topologicsverchok.

This beyond my ability. All I can suggest is to see if you have a conflicting installation of OCCT. Perhaps from FreeCAD or another topologic installation as a pure python module? On my Linux installation I have nothing OCCT related in /usr/local/lib and it works.

from topologicsverchok.

I had a similar issue and it was caused by the interaction with another Blender addon called Vi-suite which hat netgen and by this some opencascade libraries bundled. I would try deactivating all Blender Addons and cleaning all opencascade installs in the python directory

I have the same issue with the latest version [v.0.8.1.10]. I have removed Freecad installation

from topologicsverchok.

I have updated the release. Can you please delete your version and re-download and let me know? Thanks

from topologicsverchok.

This is resolved now. Thank you
