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

[David Danan]

Dear Kostas,

thanks a lot for your help! As far as i can tell, the version without interface seems to work just fine now.

The problem with the python interface remains open, python still returns the same kind of error message as in my fist email (__ZNSt12bad_weak_ptrD1Ev), so i guess i will have to manage without any interface.

Thanks again,
best regards,
David.

Dear David

So as far I see the error from the linker is
ld: library not found for -lsmumps_seq

you can try to add the path of the mumps library manually to the configure command. E.g. on some Linux distribution I use

./configure CXXFLAGS=-g -I/..some...path.../MUMPS_5.0.2/include LDFLAGS=-L/..some...path.../MUMPS_5.0.2/lib -L/..some...path.../scotch_6.0.4/lib LIBS="-lmumps_common -lpord -lmpiseq -lmetis -lesmumps -lscotch -lscotcherr -lgfortran -lpthread" --prefix=/...installation...path --enable-boost --enable-shared --with-optimization=-O2 --with-pic --enable-python --enable-metis --disable-matlab --disable-superlu --enable-mumps --with-mumps="smumps dmumps cmumps zmumps"

you can adapt this to your case.

Best regards

Kostas

Dear David

Could you please send us your config.log file after you get the errors with "checking for library containing smumps_c... no"?

Best regards

Kostas

Dear David,

The detection of the configure file is probably wrong (the search of smumps_c ...) may be the names have to be adapted in configure.ac for Mac ...
Unfortunately, I have no Mac to test it.

Dear Yves,

i checked, unfortunately i had installed the sequential version...The issue lies somewhere else.

I went back to the square one just to be sure and it seems that, even though mumps is found with the ./configure, i obtained the following result

[...]

checking for library containing smumps_c... no

checking for library containing dmumps_c... no

checking for library containing cmumps_c... no

checking for library containing zmumps_c... no

checking smumps_c.h usability... yes

[...]

Quite strange. Do you have any idea that may explain this behavior?

Thanks in advance,

David.

Dear David,

libsmumps_seq is the sequential Mumps library. May be you installed the parallel one (libsmumps). Please check.

Yves.

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

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 occur ed 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.
