Where to get SMESH?

[akloster]

When following the official build instructions with this fork, I get errors about SMESH, and SMESH_EXTERNAL is off by default. I guess I have to set it to ON and find SMESH somewhere?

[ 31%] Built target SMESH
Makefile:129: recipe for target 'all' failed

I haven't found a debian package for that, nor do I know which of the projects called SMESH is required and where to install it.

Any idea?

The message shows SMESH is built already. The error must be somewhere else. Can you please post the entire CMake output?

[akloster]

Here is the CMake Output: http://dpaste.com/1R7T3SA

Make output, from the point where the trouble seems to start: https://pastebin.com/T5qQ52b9

According to CMake output, SMESH does seem to have some problem. Maybe you can explicitly disable external search using -DFREECAD_USE_EXTERNAL_SMESH=OFF.

Also, you python executable setting ( -DPYTHON_EXECUTABLE=/usr/bin/python3.7) is wrong. It should point to an executable file instead of a directory.

My current cmake command:

cmake -DBUILD_QT5=ON -DPYTHON_EXECUTABLE=/usr/bin/python3.7 -DPYTHON_INCLUDE_DIR=/usr/include/python3.7/ -DPYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.7m.so    -DFREECAD_USE_EXTERNAL_SMESH=OFF

I noticed this in the cmake output:

-- Python:              [/usr/bin/python3.7] [-python2.7.x86_64-linux-gnu]

And now I am getting an error about shiboken2 wanting to compile something for 2.7 and missing symbols when linking:

[realthunder]

Is this /usr/bin/python3.7 a directory or an executable on your computer? Your last cmake output suggests this is a directory? If so, you should correct it to point to the actually python interpreter executable. I think shiboken2 is only available for python 3.

[akloster]

/usr/bin/python3.7 is a Python executable from the standard repository. I don't quite understand why cmake still wants to link against Python 2.7.

Oops, sorry, I was meant to say /usr/lib/python3.7. And I see that you latest cmake command has already corrected this. Have you performed a clean cmake run? Maybe you can ask around in the forum. I remember there was quite a fuss about finding the correct shiboken2 lib.

[akloster]

I managed to compile both master and the realthunder fork using Python 3.6.
