Hello,

Sorry for the late response.

I have not tried them yet. I still have the same

Code: Select all

No module _sysconfigdata_m_linux_x86_64-linux-gnu.py
error when I use shell session. There was no file named salome_context in the UB18.04 installer.

I tried to make Salome Meca 2019 work. Asking to code-aster forum, the post installation step still requires python2.
After SM2019 can be run, I tried to use salome shell session. The same error still occur.

Currently, I am moving to Pop_OS 19.04 which is based on ubuntu 19.04 to see if the error persist.
Probably should create a new thread.

Could you post a step by step by installation procedure using both salome shell and salome_context?

Kind regards,
Iwan

Hello.

This is the status that I get on Pop OS 19.04.

2. 9.3 universal (public.run)

For 9.3 Ubuntu 18.04:
- Different structure of directory
- There is no salome_context file
- code saturne successfully "make" and "make install"
- ./code_saturne gui runs succesfully
- ./code_saturne salome return:

/bin/bash: line 4: /bin/salome/envSalome.py: No such file or directory
running salome shell session return:

Hello,

The Python detection error is strange, but since you seem to have forced PYTHON=/usr/bin/python3.7, while SALOME has its own Python 3.6, this may lead to the error.

If buiding code_saturne under SALOME, you should use at least the same Python version as SALOME, and if possible, SALOME's bundled Python.

Otherwise you can simply build code_saturne independently of SALOME, using the SALOME libraries where needed (MED, HDF, ....). In this case you will not have the full SALOME desktop integration, but it is not that useful anyways (compared to the SALOME libraries). The only cases wher you really need this is if you need to do coupling with code_aster (in wich case you would be building with salome_meca), or if you need the OpenTURNS integration (available in the EDF build of SALOME, not in the generic build).

We should provide a native Ubuntu 18.04 build soon, but I do not have or master the build scripts for that yet...

Best regards,

Yvan

I already try it and it stopped at

Will try again in 18.04 then.
