Hello everybody,

I just encountered a problem when I use an installation that is linked against an already existing version of OpenMPI.

Test script that fails:

import mpi
import EMAN2

Test script that works:

import EMAN2
import mpi


If I rebuild openMPI I do not encounter this problem.

The error is:
Traceback (most recent call last):
File "testi.py", line 2, in <module>
import EMAN2
File "/mnt/beegfs/software/em/sphire/sphire_1.2_rc_007/lib/python2.7/site-packages/EMAN2.py", line 51, in <module>
from EMAN2_cppwrap import *
File "/mnt/beegfs/software/em/sphire/sphire_1.2_rc_007/lib/python2.7/site-packages/EMAN2_cppwrap.py", line 35, in <module>
from libpyAligner2 import *
ImportError: /lib64/libz.so.1: version `ZLIB_1.2.9' not found (required by /mnt/beegfs/software/em/sphire/sphire_1.2_rc_007/lib/libpng16.so.16)

Was there a known problem in the past with the order of importing EMAN2 and mpi?

Best,
Markus
