Installation on Mac OS X: error with GOMP library? #1

Hi,

I'm trying to install your code on a Mac with OS 10.7 and when I try and load the modules in python I get the following error message

In [12]: from gaepsi.tools.gaplot import *

ImportError Traceback (most recent call last) /Users/ari/Code/gaepsi/ in () ----> 1 from gaepsi.tools.gaplot import *

/Library/Python/2.7/site-packages/gaepsi/tools/gaplot.py in () 5 from gaepsi.constant import GADGET 6 from gaepsi.snapshot import Snapshot ----> 7 from gaepsi.field import Field, Cut 8 from meshmap import Meshmap 9

ImportError: dlopen(/Library/Python/2.7/site-packages/gaepsi/_gaepsiccode.so, 2): Symbol not found: _GOMP_atomic_end Referenced from: /Library/Python/2.7/site-packages/gaepsi/_gaepsiccode.so Expected in: dynamic lookup

This seems to be a problem with the GOMP library, but I'm at a loss as to how to fix it.

Thanks,

I am not familiar with macs. What compiler did you use? libgomp is the openmp library of gcc. if you use a different compiler you may have to change line in setup.py to the corresponding openmp runtime library. I haven't figured a way to automatic this.

Alternatively you can try to disable openmp entirely by removing the -fopenmp flag in setup.py - if you work on a single or dual core machine(as mac usually are) openmp won't make a huge difference I believe.
