[SOLVED] FC compilation fails with OCCT 7.6.0 beta.

[wmayer]

Yes and no. At least we can avoid to call the execute() function if only one curve has been selected because the algorithm will fail anyway.

Hello!

Now the OCCT7.6.0 seem te be finished, see here. I compiled (with make clean before) it and make a very short test with that. Rotating and padding works. But when i open FreeCAD i get error messages:

Err: libTKV3d.so.7: cannot open shared object file: No such file or directory

and

Err: libTKCAF.so.7: cannot open shared object file: No such file or directory

. In the logs are more information:

Code: Select all

.....
Log: Loading GUI of Drawing module... done
Log: Draft workbench deactivated.
Wrn: Drawing became obsolete in 0.17; consider using TechDraw instead.

Tomorrow i have more to do with FreeCAD and test more.

libTKCAF.so.7 is loaded when you import the Import or ImportGui module. So maybe you should run ldd Import.so to see if you get more information this way.

Interesting, because i have definitely installed the missing files. I must recompile it and test it again, maybe i did something wrong. Maybe the ccache of the OCCT itself spit something in my soup.

Definitivly a command which i have to remember. Thanks for helping!

When looking at other OCC libs like libTKXDESTEP.so.7 it finds them in /usr/local/lib. Is this the path where you have installed the compiled OCC 7.6?

[user1234]

Yes, same path. The export works at the moment not, because it finds not the correct shared object. But at first i want at first make all new from the scratch, before i make false alarms.

[user1234]

So, now i build all from the scratch, same behavior. It would be interesting, if other early adopter have this issue.

I have built the final OCCT 7.6 and FreeCAD linking it. When starting FreeCAD from its build directory it works to load the Part and PartDesign module but causes a crash when I try to load the Import module. The reason is that the linker doesn't find some of the shared libraries of OCCT 7.6 and tries to load the older version (7.3) instead. This is because from the installed OCCT all runpath entries are removed from the shared libraries.

When I also install FreeCAD (with make install) then FreeCAD fails to load any of the OCCT libraries. The reason is the same as above because all runpath entries are removed here, too.

In order to make FreeCAD working you must set the environment variable LD_LIBRARY_PATH that points to the directory where the shared libs of OCCT are located.

[user1234]

Stupid question: what is the reason why this happen, especially when i wiped OCCT completely before from the computer. Also i can image, when forget to set the flags to install the tk files, then this happen, but i set the flags and installed this, also they are in the correct place. (I also wiped FreeCAD completely and make all new).

Stupid question: what is the reason why this happen, especially when i wiped OCCT completely before from the computer.

It depends on what directories are listed in the .conf files under /etc/ld.so.conf.d
