Hello all,
I am trying to run the telemac2d API simple example in Ubuntu 22.04.1 (after failed to run it in windows 10), I am using Telemac v8p3r1. I am facing the following error
Traceback (most recent call last):
File "/home/mohamed/telemac-mascaret/v8p3r1/scripts/python3/telapy/api/api_module.py", line 171, in __init__
import _api
ImportError: /home/mohamed/telemac-mascaret/v8p3r1/scripts/python3/_api.so: undefined symbol: mpi_allgather_
During handling of the above exception, another exception occurred:

and I am trying to run the example with the following commands:
$ source pysource.sh
$ python3 Trial.py
as (Trial.py) is the Api example.
Note: I tried to use v8p2r1 and faced the same error.
Can anyone help me, please?
