Re: Salome Meca 2021 on WSL2

If you run, say

xclock

Does it appear?

If you are using WSL2 with integrates graphics, you can try running salome_meca directly...

Re: Salome Meca 2021 on WSL2

Ok you clearly have a problem with the graphics part (this is indépendant of salome meca).

You need to install an x server like VcXsrv in windows so that you can run graphical apps in wsl.

It should be straightforward.

I did actually following your procedure and recommandations but it still doesn't work.
I give up, i'm happy with the Linux version.

Perfect!

Glad to know it works finally.

These warnings are harmless.

Re: Salome Meca 2021 on WSL2

I try to run it with a batch file.

cd c:\salome_wsl
wsl --distribution SalomeMeca2021 --user user
start salome_meca

however powershell opens but the salome_meca command is not executed.

Re: Salome Meca 2021 on WSL2

Maybe it fails because it need an executable script to run.

If I'm not mistaken salome_meca is a function in .bashrc

Try :

type salome_meca

And see the output

Then copy that in a separate executable  script (xxx.sh) that you call explicitly from your batch file.

And please share the results to benefit the whole community.

Best regards

Re: Salome Meca 2021 on WSL2

This my batch file salome.bat:

cd c:\salome_wsl
wsl --distribution SalomeMeca2021 --user user
./salome.sh salome_meca

cmd /k

This is my shell file salome.sh:
function salome_meca ()
{
    echo "INFO: Running salome_meca on wslg display (rdp implementation)";
    fix_shm;
    singularity run -B /mnt/wslg salome*.sif
}
$1

Unfortunately this doesn't work.
The batch file opens a terminal but doesn't execute salome.sh

C:\WINDOWS\system32>cd c:\salome_wsl

c:\Salome_WSL>wsl --distribution SalomeMeca2021 --user user
user@DESKTOP-PMGA9BL:/mnt/c/Salome_WSL>

Re: Salome Meca 2021 on WSL2

Hi hberro,

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

Thanks.

Hi carv,

> md5sum smeca-lgpl-wsl2-opensuse.tar
8609ad7ac072c5a2cc998b3ef324415f  smeca-lgpl-wsl2-opensuse.tar

Best regards

Thank you hberro! It's working now. Finally.

Re: Salome Meca 2021 on WSL2

Many thanks for this guide. I was able to get it working on Windows10/WSL2.

Since I don't always remember the function name, I made a bash script to launch:
Salome.sh

#!/bin/bash
#launch salome-meca
salome_meca_xlaunch

make executable

sudo chmod 777 Salome.sh

but found I had to add this to the .bashrc file for the script to work:

export -f salome_meca_xlaunch

Re: Salome Meca 2021 on WSL2

When running salome-meca on WSL the mouse pointer is very big
Can'f find a way to diminish the cursor.

Re: Salome Meca 2021 on WSL2

Following the instructions of post 1 of this thread, I obtained a running version of salome-meca.
It had a few problems:
1. It ran in software GL mode, although my computer has a mobile Nvidia card
2. Perhaps as a consequence, updating the screen was often incomplete, but the screen could be updated by switching between steps in aster-study.
3. Although the interactive performance was adequate for a simple tutorial, running the tutorial consumed very little resource, but consumed about 2 hours of wall-clock time (Divijay Patankar example 2 https: / / youtu.be/qZxoJVP0L98).

In response I have begun to explore WSL2/Ubuntu22.04/Singularity.
Should new installations use Apptainer in lieu of singularity ?
If using the debian package for singularity (https: / / github.com/sylabs/singularity/releases/download/v3.10.1/singularity-ce_3.10.1-jammy_amd64.deb) , is it necessary to also build golang and other pre-requisites of a source installation ?

Thank-you

Re: Salome Meca 2021 on WSL2

I did an experiment.
Running Windows 11 and WSL2, build 22621r1
Fresh windows store install of Ubuntu 22.04

install golang from a linux binary
sudo tar -C /usr/local -xzf go1.18.4.linux-amd64.tar.gz

install singularity from a debian package:
wget -c https:/ /github.com/sylabs/singularity/releases/download/v3.10.1/singularity-ce_3.10.1-jammy_amd64.deb
sudo apt install ./singularity-ce_3.10.1-jammy_amd64.deb

prep directories - not sure if it is required, but I took a suggestion from this forum.
sudo rm -r /dev/shm
sudo mkdir /dev/shm
sudo chmod 777 /dev/shm
chmod 777 .singularity/

Also, from a suggestion of this forum:
curl -sfL https:/ /install.goreleaser.com/github.com/golangci/golangci-lint.sh | sh -s -- -b $(go env GOPATH)/bin v1.21.0

sudo singularity run --app install ./salome_meca-lgpl-2021.0.0-2-20211014-scibian-9.sif
singularity run --app install ./salome_meca-lgpl-2021.0.0-2-20211014-scibian-9.sif

Now, running the script does find the GPU, but it generates errors and exits.

./salome_meca-lgpl-2021.0.0-2-20211014-scibian-9
not exist: /etc/krb5.conf

On the hypothesis that the singularity container had a strict x-server requirement, I tested x11-apps.
sudo apt install x11-apps

NOTE: xclock and xcalc display properly and run fine.

vcxsrv on Xlaunch on windows did not change the result.

I appreciate your consideration and suggestions to install the singularity salome-meca either on Ubuntu, or in a workably fast installation following the instructions for the prepared debian distribution.

Kind regards.
