Re: [Getfem-users] Error with the python interface

[David Danan]

Dear Getfem users,

beside the interface problem, i noticed that there is another issue. When i compile the test case elastostatic.cc, for instance, i get the following error message

ld: library not found for -lsmumps_seq

And since i am on Mac, i didn't find how to obtain the missing library (as recommended on the Getfem download page, i used brew to download mumps but that's it). Is there anyone who had a similar problem on Mac?

Thank you in advance,

David.

Sujet : Error with the python interface

Dear Getfem users,

I have just installed Getfem on a mac but i have trouble with the python interface.
The compilation process occured without major issue, but when importing python in a demo example, I get the following error

Traceback (most recent call last):
  File "demo_laplacian.py", line 30, in <module>
    import getfem as gf
  File "/usr/local/lib/python2.7/site-packages/getfem/__init__.py", line 16, in <module>
    from getfem import *
  File "/usr/local/lib/python2.7/site-packages/getfem/getfem.py", line 44, in <module>
    from _getfem import *
ImportError: dlopen(/usr/local/lib/python2.7/site-packages/getfem/_getfem.so, 2): Symbol not found: __ZNSt12bad_weak_ptrD1Ev
  Referenced from: /usr/local/lib/python2.7/site-packages/getfem/_getfem.so
  Expected in: flat namespace
 in /usr/local/lib/python2.7/site-packages/getfem/_getfem.so

I had this issue with the options "-enable-python=yes --with-pic" for configure.

Do you have any clue about the cause of the problem ?

Thank you in advance,
David.
