FreeCAD Slackwarex64 -Current can't open libTKFillet

enine · 06-16-2016, 06:15 PM

I built FreeCAD on my x64 -current box today and am getting the following

Code:

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/opt/FreeCAD/Mod/Draft/importDXF.py", line 45, in <module>
    import sys, FreeCAD, os, Part, math, re, string, Mesh, Draft, DraftVecUtils, DraftGeomUtils
ImportError: libTKFillet.so.0: cannot open shared object file: No such file or directory

I used the -current Slackbuilds https://github.com/Ponce/slackbuilds

I found this http://forum.freecadweb.org/viewtopic.php?t=13646

But looking at the date/time on the packages I see that I built VTK before opencascade so the fix there doesn't seem to be my problem.

I didn't post http://www.linuxquestions.org/questi...ls-4175561999/ because the build works fine. Its when I tried to open a file I get the erorr.

Did you built FreeCAD only or rebuilt every deps as well?

enine · 06-16-2016, 07:25 PM

I built all the deps. Its a clean install of -current, burned an iso a week or so ago and put a new ssd in and did a fresh install. So there wasn't any old deps, all were built new.

So, what is the output of...

Code:

ls -l /usr/lib64/libTKFillet*

...?

EDIT: I intend to run FreeCAD on this system when I upgrade to 14.2, so I'm curious about the fix.

Hmm, not found. I thought it was part of one of the packages I built so where did it go.
Am I right that its part of VTK

here it is

Code:

root@darkstar:/# ls /opt/OpenCASCADE/lib64/libTKFillet*
/opt/OpenCASCADE/lib64/libTKFillet.la*
/opt/OpenCASCADE/lib64/libTKFillet.so@
/opt/OpenCASCADE/lib64/libTKFillet.so.0@
/opt/OpenCASCADE/lib64/libTKFillet.so.0.0.0*

Based on a quick Google search, it seems like it should be a part of OpenCASCADE.

Yea, I found it under opencascade.

Richard Cranium · 06-16-2016, 10:27 PM

I rather suspect, in that case, that either the cmake build for FreeCAD needs to be told where to find it or you can edit /etc/ld.so.conf to have it available at run time.

FWIW, I think that editing /etc/ld.so.conf would be the wrong thing to do.

Hi enine, thanks for the very useful report, I can reproduce it easily here, sorry for the cockup

I recognise the essential truth of what Mr Cranium says about /etc/ld.so.conf, but adding /opt/OpenCASCADE/lib64 may be a relatively clean solution, since FreeCAD does not use a wrapper script.

Alternatively, I could write a trivial wrapper script.

Yeah, ok, I'll write a wrapper script.

Edit: wrote a wrapper script.

Quick and dirty, you can remove the symlink /usr/bin/FreeCAD, and put this script at that location, and make it executable:

Code:

#!/bin/sh
export LD_LIBRARY_PATH=/opt/OpenCASCADE/lib64:$LD_LIBRARY_PATH
exec /opt/FreeCAD/bin/FreeCAD "$@"

I'll push a new FreeCAD build to SBo git master soon.

Thanks, 55020. This is why I made the Open Source switch years ago. I still have tickets with Microsoft for bugs I reported in server 2003

Only minor issue, if I just run FreeCAD it errors, I have to specify /usr/bin/FreeCAD to run your wrapper. Apparently FreeCAD is elsewhere in the path getting found first.

Off to try printing my son a Google Cardboard

Try to see here if it cankarjeva help https://github.com/saxa/slackbuilds/...uild-order.txt
But i think you have to configure correctly opencascade.

I just ran into this after updating OpenCASCADE. After rebuilding FreeCAD, the issue went away.

Could it be possible to have the FEM module working?
I think it needs some other packages like netgen and/or GMSH and calculix?

I believe so.
