Replace the libs with the ones i posted anyway.
arena10 missing leads to linking to outdarted tbbmallic in sys.
My embree avoids this.

You may have an older versions of Intel TBB library installed. Try to run the following command line:

Code: Select all

ldd /home/egert/.config/blender/2.79/scripts/addons/BlendLuxCore/bin/pyluxcore.so
This is the output in my case:

Post your output here. We have to check the following lines:

Code: Select all

	libtbb.so.2 => /home/david/projects/luxcorerender/embree-2.17.1.x86_64.linux/lib/libtbb.so.2 (0x00007f9ec9a5e000)
	libtbbmalloc.so.2 => /home/david/projects/luxcorerender/embree-2.17.1.x86_64.linux/lib/libtbbmalloc.so.2 (0x00007f9ec980a000)
because I'm pretty sure you are missing the /home/david/projects/luxcorerender/embree-2.17.1.x86_64.linux/lib/libtbb*.so.2 files or they are resolved with some older version installed in your system.

Pyluxcore.so is NOT the problem, see again: viewtopic.php?f=4&t=193&sid=005e28407a6 ... 8ec7#p2510

Use my libs, specifically the tuned libembree, period.

You can use all the "period" you like and be still wrong.

I found my problem, why LuxCore did not work. I downloaded blender via command line and installed it, but then those errors occurred. Now I downloaded it straight from blender.org and everything works. Except my gpu, that is something that I still need to fix, then I can start experimenting with Linux version

In that case your Blender version was probably outdated.
BlendLuxCore only works with 2.79a and above, there are some bugs and missing features in lower Blender versions.
