2018 is working, Sigsev Fault on 2019 for Ubuntu 18.04

Hello all,

OS:  Ubuntu 18.04 (physical installation)
GPU: Radeon RX 460

I am having an issue where I get "Segmentation Violations" errors when I try to run Salome-Meca 2019 and enter the mesh module, causing the program to crash.  I see that others have made similar posts, and I have tried some of their solutions (hopefully this compiled list will help others with these problems).  I HAVE gotten Salome-Meca 2018 to work using the libstdc++ trick below.

- Installed all prerequisites

code-aster.org/IMG/pdf/sm2019_ubuntu18_install.pdf

- Install OEM drivers for graphics card (Radeon RX460)

- Run installation using sudo (sudo ./salome_meca-2019.0.3-1-universal.run)

code-aster.org/forum2/viewtopic.php?id=24678

- I have NOT tried the solution suggested by cbourcier to install mesa-salome and point to those libraries, because it looks like Salome's server is down at the minute.  I did try this previously on a virtaul machine, and while it allowed the program to start, I could still not display a mesh in the AsterStudy, and the solver gave an error "It misses the mesh!", which I assume was related.

code-aster.org/forum2/viewtopic.php?id=23568#p60155

-  Comment out libstdc++ files using underscore (~/salome_meca/V2019.0.3_universal/prerequisites/debianForSalome/lib)
***This solution DID work for 2018, which I AM currently running***

code-aster.org/forum2/viewtopic.php?id=23487

- LD_PRELOAD command before ./salome

code-aster.org/forum2/viewtopic.php?id=23547

I have also attached the output from the terminal for 2018 when I do NOT comment out the libstdc++ files.  Maybe that contains some clues?

Any suggestions on what I can investigate next would be greatly appreciated.  Thank you!

-Mike

I personally believe that the error lies in the installation with sudo.
The libstdc++ must be commented if you are not in Debian.

Try to install without sudo in default directory.
Comments libstdc++  files.
Execute ./salome.
post the output on terminal.
Nothing else.

Re: 2018 is working, Sigsev Fault on 2019 for Ubuntu 18.04

Even I am getting same error shown. But still I can open the application. Problem is that when I try to compute the mesh, mesh is not generating. On the terminal it displays the error :

Can't compile vertex shader.
0:1(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES
Please help me to sortout this error.

Thank You

Re: 2018 is working, Sigsev Fault on 2019 for Ubuntu 18.04

Thank you Sameer..
I followed all steps mentioned in page 2 and now I am not getting GLSL error. I am able to compute mesh without error. But I continue to get the warning mentioned above while launching ./salome. I am running on physical system  (ubuntu 18.04) but it does not have graphics card. Is this the reason to get such warning?

Thank you in advance.

Re: 2018 is working, Sigsev Fault on 2019 for Ubuntu 18.04

you hv to use ASTK for running solver. Go to Tools, PlugIn, Codeaster, Astk.

as from salome-meca - running solver may crash and takes much more time.

don't worry on your above plugin messages.
