Hi,
replying to some of your questions:
Add & remove Modules buttons (Add/remove modules dynamically — GUI 9.12.0 documentation).
This feature is not supported in this release. Thus it should not be used, since anyhow you’re missing these so called .salomex files. This feature is a work in progress feature and will be operational in one future SALOME release.
Then, concerning this second point:
I read here (3. What do I need to install on my workstation to run or build SALOME? - SALOME PLATFORM) that using SAT tool after installation will help mitigate issues and install any dependencies, but when I run that command in my command prompt
./sat config SALOME-9.8.0 --check_system
The mentionned command line should read in case of an Ubuntu 22 SALOME 9.12 archive:
cd SALOME-9.12.0-native-UB22.04-SRC
./sat/sat config SALOME-9.12.0-native --check_system
This command will check whether some of the system prerequisites are indeed installed on your Linux distribution, here Ubuntu 22.04. In case some of them are not found, they will be reported as missing and you will have to install them.
If you experience issues running this command line, do not hesitate to raise the issue on this forum.
HTH.
