luxcoreui failed with segmentation fault - Linux (Debian)

Post by harishankar » Wed Jun 24, 2020 6:53 am

I downloaded the latest luxcorerender (stand alone) and it crashes with the following segmentation fault:

Code: Select all

LuxCoreUI v2.3 (LuxCore demo: http://www.luxcorerender.org)
Segmentation fault
I just extracted the tarball into a directory and executed ./luxcoreui from the command line. I don't know what is the issue. Please let me know if any further information is required.

What CPU do you have ? The binaries can not work on some very old CPU.

Are you using the OpenCL version or the CPU-only version ?

To get more information, you can do the following:

Code: Select all

gdb ./luxcoreui
run
backtrace
(the first command opens a gdb debugging session, the next are gdb commands to get a backtrace)
You can then copy/paste the output here.

Both the normal version and OpenCL version failed to run.

By the way the blender add on works. But I want to use the stand alone version.

My CPU is

cat /proc/cpuinfo

But are you using an headless terminal ? It looks like your OpenGL support is broken. For command line rendering, without any visual feedback you should use pyluxcoretools console command.

Not using a headless terminal. Also OpenGL works for me. At least, glxgears works fine. I am using a laptop with dual Nvidia (dedicated) and intel graphics chip. glxgears works with both primusrun and without primusrun.

The crash is at the initialization, inside https://www.glfw.org

There is something in your system GLFW doesn't like at all.

As workaround, try to use the console-only (no OpenGL output) command (pyluxcoretools, console option).

:? I am using Gnome on wayland. Probably this is causing an issue. Will try again with Gnome on X server.

EDIT: well, it works with Xorg. So Wayland was the issue. Thanks for your help.
