import an external library

PYTHONPATH=. yade-daily Simple.py

should fix your problem, if nsmp1d_yade.so is in the current folder.

or inside the script (in the beginning)

import sys
sys.path.append('.')

the solution is the same as Anton's one

Thanks for the answer, I tried both solutions one by one, but both lead to another error :
Welcome to Yade 3+3698+47~precise1
TCP python prompt on localhost:9000, auth cookie `dascks'
XMLRPC info provider on http://localhost:21000
Running script Simple.py
Erreur de segmentation (core dumped)

translation : segmentation fault

and I don't know how to fix that.
Any idea ?

Thanks
Raphael

(The script is still working in python)

It should be debugged. Can be related to a LP:1183402 [1].
