Issues with running Salome (SALOME-9.8.0-native-UB20.04-SRC)

Install & build
1

I’ve been trying to install Salome for a couple of days now and I can’t find the workaround to the last problem I encountered. I already changed Python so Python3 is used whenever I call it, I installed all the missing dependencies(but one), then I installed Salome and… When I try to open it using ./salome it outputs these lines:

ERROR:salomeContext:Unexpected error:
Traceback (most recent call last):
  File "/home/jahir/Escritorio/CFD/SALOME-9.8.0-native-UB20.04-SRC/BINARIES-UB20.04/SALOME/bin/salome/salomeContext.py", line 279, in _startSalome
    res = getattr(self, command)(options) # run appropriate method

    import _omnipy
ModuleNotFoundError: No module named '_omnipy'

What am I supposed to do now? I tried some methods given in other threads with no success. :slightly_frowning_face:

Assuming that : python --version returns Python 3, you can try to do the following to check that you have all shared objects installed ?

source ./env_launch.sh
ldd SALOME-9.8.0-native-UB20.04-SRC/BINARIES-UB20.04/omniORB/lib/python3.8/site-packages/_omnipy.cpython-38-x86_64-linux-gnu.so

You should have something like:

ldd SALOME-9.8.0-native-UB20.04-SRC/BINARIES-UB20.04/omniORB/lib/python3.8/site-packages/_omnipy.cpython-38-x86_64-linux-gnu.so

        libomnithread.so.4 => /home/salome/releases/SALOME-9.8.0-native-UB20.04-SRC/BINARIES-UB20.04/omniORB/lib/libomnithread.so.4 (0x00007f71e218f000)

I just did that and the output is almost the same as yours (just different memory locations), but when I use ./salome it still sends the same error message.

Thanks for the reply.

EDIT: I should’ve said this before, but I’m using Ubuntu 21.10. I don’t know if that makes any difference.

I strongly suggest you to use the universal binary in that case, since UB21 is not tested).
Please read carefully the README file about possible actions in the SALOME launcher
HTH.

Thanks, I was thinking about doing that, it seems like a better option.
