Re: Salome Meca 2021 on WSL2

I had the problem reported above of the application not launching (nor the xclock), through the VcXsrv method (on Windows 10), the error was.

'Error: Can't open display: 172.29.208.1:0'

The problem is Windows' firewall blocking the connection. I found the solution in the following page:

https: // github.com/cascadium/wsl-windows-toolbar-launcher#firewall-rules

Hope this helps someone!

Re: Salome Meca 2021 on WSL2

Hi hberro,

Thank you for all your help.

There is some update in the last link you released?

Because I can't run the CodeAster in WSLg yet, using the first link.

Regards,

carv

Hi carv,

No there is no update in the last link, it is the same file as in the first post. Did you try guillegiraldo's link to try to figure out the Firewall settings for Windows ?

Re: Salome Meca 2021 on WSL2

Hi all,

i have installed two different wsl2 instances. An Arch-Linux and the opensuse distro but i get the exact same error like carv did on both machines. The X11-Forwarding is working as i get xterm and xclock clients to display on the vcxsrv-Server.

I tested "xclock" and the clock shows me.

What am I doing wrong?

Do you have any advice on were i can look further?

Re: Salome Meca 2021 on WSL2

HI Celdor,

I'm have the same error yet.

I don't have much free time to try some fixing action.

If you find some solution please share.

Hello,

Please refer to the initial post and run the command

salome_meca

In the folder containing the sif file.

You should not run the sif file directly using singularity run xxx.sif

Re: Salome Meca 2021 on WSL2

Reminder regarding the automatic launchers present in the WSL distro:

> salome_meca
For WSLg

> salome_meca_xlaunch
For using an xserver configured on the windows side

These launchers apply a fix to the /dev/shm access and do some bindings when launching the singularity container. If you launch singularity run manually, it is almost certain it will not work.

Re: Salome Meca 2021 on WSL2

Hi hberro,

thanks for your reply. Didn't realize that salome_meca[_xlaunch] where seperat scripts to start the container, not generated by the singularity-install described in the general download. My fault. Sorry.

This method works for X11.

Thank you. :-)

Could you post the checksum for the "code-aster.org/FICHIERS/wsl/smeca-lgpl-wsl2-opensuse.tar" file?

Thanks.

Can you try to run the distro as "user"

wsl --distribution SalomeMeca2021 --user user

The shortcuts to these scripts (salome_meca*) have been added to this user profile only if I'm not mistaken (have a look at the ~/.bashrc file)

I suppose I make some stupid mistake however I'm a structural engineer with limited knowledge of programming :-)

Re: Salome Meca 2021 on WSL2

The previous command needs to be launched in windows cmd prompt directly and not within the wsl distro.

Re: Salome Meca 2021 on WSL2

When you imported the tar file for the distro, did you use the command ?

wsl --import SalomeMeca2021 C:\Data  C:\Downloads\smeca-lgpl-wsl2-opensuse.tar

For me, it seems that you didn't exactly name your WSL distro as recommended (SalomeMeca2021)

In order to list the WSL distros in your system : (windows command prompt)

wsl --list --all
