salome meca 2021 installation problems

Hello,

I'm installing Salome Meca 2021on Ubuntu 18.04 using WSL2. I installed Singularity successfully as described in the installing guidelines.
When trying to launch the application with:

./salome_meca-lgpl-2021.0.0-1-20210811-scibian-9 --soft

I get the following error:

not exist: /etc/krb5.conf

*****************************************************

Any idea on which could be the error?

Re: salome meca 2021 installation problems

for me error is due to base OS,try ubuntu 20.04, there should be for WSL ....
for install singualrity i used this procedure ( on linux native xubuntu 20.04 )

sudo apt-get update && \
sudo apt-get install -y build-essential \
libseccomp-dev pkg-config squashfs-tools cryptsetup

sudo rm -r /usr/local/go

export VERSION=1.13.15 OS=linux ARCH=amd64  # change this as you need

wget -O /tmp/go${VERSION}.${OS}-${ARCH}.tar.gz https://dl.google.com/go/go${VERSION}.${OS}-${ARCH}.tar.gz && \
sudo tar -C /usr/local -xzf /tmp/go${VERSION}.${OS}-${ARCH}.tar.gz

echo 'export GOPATH=${HOME}/go' >> ~/.bashrc && \
echo 'export PATH=/usr/local/go/bin:${PATH}:${GOPATH}/bin' >> ~/.bashrc && \
source ~/.bashrc

curl -sfL https://install.goreleaser.com/github.com/golangci/golangci-lint.sh |
sh -s -- -b $(go env GOPATH)/bin v1.21.0

mkdir -p ${GOPATH}/src/github.com/sylabs && \
cd ${GOPATH}/src/github.com/sylabs && \
git clone https://github.com/sylabs/singularity.git && \
cd singularity

git checkout v3.6.3

cd ${GOPATH}/src/github.com/sylabs/singularity && \
./mconfig && \
cd ./builddir && \
make && \
sudo make install

singularity version

Re: salome meca 2021 installation problems

Hello,

I tried your installation for singularity and then I tried to install on WSL2 running Ubuntu 20.04 and I got exactly the same error.

Hi Filjan,

Unfortunately didn’t manage to get around it so far.
Of course I’ll let you know in case I manage.

Re: salome meca 2021 installation problems

I guess I ran into the same issue. The only difference I see at the end: "OSError: Error 30] Read-only file system"

Was there any possibility to let it run?

Re: salome meca 2021 installation problems

Hello,
I get the same identical error on WSL2 with both Ubuntu 18.04 and 20.04 and with Debian too.

Hello Urs, you will have the same error as me if you would run with --soft option.
Still didn't manage to get the answer, unfortunately

Re: salome meca 2021 installation problems

Hello,

you could try a newer version of singularity. A similar error has been reported with Ubuntu 18.04:

Re: salome meca 2021 installation problems

Any news on this issue?

I tried with singularity SingularityCE 3.9.0 RC1 and Singularity 3.7.4 on wsl2 18.04. Same error as described already. Seems to stall on GUI as other continers work normally.

Thanks and regards.

Re: salome meca 2021 installation problems

At one point during our tests on WSL2, we found it necessary to do the following

sudo rm -r /dev/shm
sudo mkdir /dev/shm
sudo chmod 777 /dev/shm

Hope it helps, let us know please.

After running these commands salome-meca now works correctly. Thank you very much.

Re: salome meca 2021 installation problems

To be honest the output error is too generic to give you advice, did you follow the steps specific for WSL2 ?

Re: salome meca 2021 installation problems

Contrary to some of the posts above, and following the instructions to the letter, I installed SM2021 on Ubuntu 20.04 without any hiccups. My compliments to the developers. This was a pleasure. Keep up the good work.

Loading an existing simulation into 2021, I encountered 2 problems.

1. I can only access the installation disk. /mnt and /media are both empty. This is not insurmountable but inconvenient.

2. In the simple viewer in Code-Aster I can pan and zoom, but I can not rotate the image. For me this is serious because this is my preferred viewer.

Any help with the above will be appreciated

Re: salome meca 2021 installation problems

Thank you so much for your guidance it helped a lot.

I am not sure why, but it did help creating launcher on desktop (I use xfce) pointing to salome_meca executable file, as running it from terminal results in my above mentioned general error.

For all finding typing sudo commands before start tedious this might help:

1. creating excutable e.g. salome.sh with:

#!/bin/sh -e
set -e
rm -r /dev/shm
mkdir /dev/shm
chmod -R a+rwx /dev/shm
exit 0

2. setting up crontab: https:_____//phoenixnap.com/kb/crontab-reboot" , putting in crontab file e.g.:
@reboot sleep 10 && /here_put_your_path_to_executable/salome.sh

3. making crontab service start on wsl2 startup, since it is stopped by default at each startup: https:____//askubuntu.com/questions/1165969/ubuntu-18-04-on-wsl-cron-daemon-not-running-after-reboot

There might be other ways to approach this, running salome.sh as service, but in my case those didn't work.

Regards

Well, since I'm no IT specialist I'd be glad if someone could help me and others running this great piece of software.

Re: salome meca 2021 installation problems

OK. I tried to install Salome-Meca2021:
- on separate drive with Ubuntu 20.04 LTS with no success
- on Windows 10 Pro with Ubuntu 20.04 LTS with WSL2 - no success
- on Virtual Box machine with Ubuntu 20.04 LTS - no success
- on Hyper-V with Ubuntu 20.04 LTS also with no success (also graphics work slowly on that last one)

I also tried to install Salome-Meca2018 & 2019 on separate drive with Ubuntu 20.04 LTS - still no success

Then I tried to install Windows port of Salome Meca 2019 where I shuld install Microsoft C++ redist version 2014 which you can't find on the Internet (2013 and 2015 are easy to find)...

As you can see I really want to run it. The most desirable solution would be running under Windows via WSL2, but that seems to be out of my reach. HELP, HILFE, Au secours!

Re: salome meca 2021 installation problems

Hi!

for me help EnKiNekiDela hint about bulding executable in the desktop and running through xfce4 window (Thanks!). Trying to run salome_meca through wsl terminal indirectly ends with failure though. Working through xfce has unfortunately some inconvienient lags : /

@ k_zurawski - I assume you are Polish too - don't hesitate to write me message in any question, I'll be glad to help.

Best regards,
Filjan

Edit:
PS: I forgot to mention that this time I've used Ubuntu 18.04.

Re: salome meca 2021 installation problems

Hello

for those having problems starting Salome-Meca 2021 in WSL with the following error :

"Searching /Kernel/Session in Naming Service  ++++++++++Traceback (most recent call last):
  File "/opt/salome_meca/Salome-V2021-s9/modules/KERNEL_V9_7_0/bin/salome/orbmodule.py", line 181, in waitNSPID
    os.kill(thePID,0)
ProcessLookupError: [Errno 3] No such process"

There is  a simple fix: you have to :
1. make sur that you have a X Window server running (like VCXSRV). Settings: disable access control, enable OpenGL, choose display number = 1
2. set your DISPLAY environment variable to point to the IP and display number

for example, if your PC has IP 192.168.0.222 and you have VCXSRV running for display # 1:

export DISPLAY=192.168.0.222:1
/path/to/salome/salome_meca-lgpl-2021.0.0-0-20210601-scibian-9 --soft

I did try this using Ubuntu 20.04 in WSL2, and following the steps defined here :
https:// github.com/emefff/Code-Aster-MPI-in-Singularity-of-SM2021

I did follow all the steps except the modification of the container image and Aster compilation. Instead I skipped to download directly the modified image with MPI version of Code-Aster.


Also I found necessary to run at least once those commands as stated before:

sudo rm -r /dev/shm
sudo mkdir /dev/shm
sudo chmod 777 /dev/shm

PS: small additionnal note
After rebooting, Ubuntu in WSL will recreate /dev/shm as a link to /run/shm.
To make it work again you will have to:

 
sudo rm -f /dev/shm
sudo mkdir /dev/shm
sudo chmod 777 /dev/shm

(note rm -f not rm -r as we are deleting the symlink to create a new directory as /dev/shm and make it RW for all)
