Solved! blendluxcore crash at render time (see last post)

[xsinick]

When I render a standard cube with a basic LUX material blender crashes on Linuxmint.
I get this error:

[SDL][245.975] Material definition: Surface_Material_140521094170632
Illegal instruction (core dumped)

If I render an empty scene it does not crash.
I looks like some sort of material error in SDL? Help Please!

[B.Y.O.B.]

Are you using the latest version (rc1)?
Can you upload the scene?

Thanks for the response BYOB.
Here is a link to the scene:

Same issue here on Ubuntu 14.04 : crashes with default scene but does run once cube has been deleted

Same thing goes for running luxcoreui from shell here's what I get :

LuxCoreUI v2.0rc1 (LuxCore demo: http://www.luxcorerender.org)
[LuxCore][0.001] Configuration:
[LuxCore][0.001] film.width = "512"
[LuxCore][0.001] film.height = "512"
[LuxCore][0.001] image.filename = "cornell.png"
[LuxCore][0.001] scene.file = "scenes/cornell/cornell.scn"
[SDL][0.001] Reading scene: scenes/cornell/cornell.scn

CPU ? GPU ? Do you have an SSSE3 capable CPU (notice the 3 "S" and not 2)

This is scene is working fine here. Do you experience a crash only with this scene or with any scene ? CPU ? GPU ?

No ! Old laptop. Will that new release of Luxrender only work on SSSE3 CPUS ?

At the moment, yes, it requires SSSE3 for Linux. Boost library apparently uses SSSE3 pshufb instruction and it is not supported by AMD Phenom II and some other old CPU (before 2010). The problem was investigated in this issue: https://github.com/LuxCoreRender/BlendL ... issues/114

You can still compile LuxCore on your own as described here https://github.com/LuxCoreRender/LinuxCompile but it is not an easy task if you are not a developer.

Thanks Dade. It's indeed a CPU which doesn't support SSSE3. Will try to get a new laptop soon in the meantime I will give a shot at trying to compile LuxCore following the instructions on Github.
