Hello,

Are you using Linux inside a virtual machine?

Hello,
I had exactly the same problem on Mint 18.1, with an old computer without graphics card. I added a cheap graphics card and it's working perfectly now.

Salome Meca 2017 was running fine without graphics card.

Hi there,

I can confirm this. When using Intel integrated graphic card it leads to same problem in my laptop. Change to Nvidia graphic card solve the problem.

Yes, I'm facing this very same problem when attempting to run SalomeMeca within ubuntu 19.04 under Parallels. I guess it's related to the lack of support for OpenGL 3.3, but I wonder if it's possible to workaround this

Hi,

A workaround is available in latest version of Salome by using mesa3d to provide libGL.so with software rendering.

Download Salome from salome-platform.org/downloads/current-version

Choose the version specific to your OS (not the universal binary which does not contain mesa3d).

Launch salome with ./mesa_salome

If it works, you can use env_launch.sh with only llvm and mesa sections to append llvm and mesa to LD_LIBRARY_PATH before launching salome_meca.
