Error with gui scripts / python

[Support TGCC]

Hi,

I'm a member of the support applicative team of TGCC (http://www-hpc.cea.fr/fr/complexe/tgcc.htm). An user with its own installation have an issue with the command "code_saturne gui".

We have reproduce the issue with version 3.0.0. and a print debug report this :

$ code_saturne gui
set_modules
pkg : <cs_package.package instance at 0x2b596a4f3b90>
pkg.env_modules :
pkg.env_modulescmd :
cmd_prefix :

errread, errwrite)
File "[..]/lib/python2.7/subprocess.py", line 1249, in _execute_child
raise child_exception
OSError: [Errno 13] Permission denied

How to fix it ?

Hello,

Do you know if environment modules were loaded when the code was configured ? Code_Saturne tries to determine which modules are loaded at "configure" time, so as to record the and load the same modules when running, but this assumes a Python environment module API. This works on most machines, but has been know to fail on Curie, where the environment module script seems to be an older, tcl or shell only version (if I remember correctly; at least this seemed to be the case a year ago).

So it may be better to configure adding the "--with-modules=no", then load the modules either through the user's environment, or through a shell script sourced using the rcfile setting in the codes <install_prefix>/etc/code_saturne.cfg in the post-install stage (this is the same file in which "batch = CCC" should be set for the TGCC or CCRT systems, so it should already be present).

Hello,

Add the option "--with-module=no" works perfectly without any other modification.
Thanks a lot for your help
