Activation problem with V 2.3

[Rebo2000]

Hi there,

I have a problem with the new version of LuxcoreRender V2.3. Installation works fine, but when I try to activate it I get the following error:

Code: Select all

Traceback (most recent call last):
  File "/home/toni/Blender/blender-2.82a-linux64/2.82/scripts/modules/addon_utils.py", line 351, in enable
    mod = __import__(module_name)
  File "/home/toni/.config/blender/2.82/scripts/addons/BlendLuxCore/__init__.py", line 23, in <module>
    raise Exception(msg + "\n\nImportError: %s" % error) from None
Exception: 

Could not import pyluxcore.

ImportError: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not found (required by /home/toni/.config/blender/2.82/scripts/addons/BlendLuxCore/bin/pyluxcore.so)

My System is Linux Mint 18.3 Sylvia 64 Bit, Kernel 4.4.0-150-generic x86_64, Mate 1.18.0
Blender Version is 2.82a

any thoughts ?

any thoughts ?

The glibc version required by the binaries is not available on your system. I don't know Mint distribution and if you can install the required version otherwise compiling directly from the source may be the only solution.

Mint is based on Ubuntu.

The 18 release is still based on Ubuntu 16.04, if I'm not mistaken.

I think you need at least an Ubuntu 18.04

Ok, I installed a new system and a new NVidia Card... and got new problems :

No idea what to do.

Your OpenCL installation is likely to be missing or broken. Try to run LuxMark first, if it doesn't work, try to re-install your GPU driver and/or OpenCL ICD.

Thanks for the push in the right direction @dade
I fixed the problem with

Code: Select all

sudo apt-get install ocl-icd-libopencl1

...if someone has the same problem
