[MOAB-dev] pytaps: can't import iBase and iMesh

Tue Jun 10 02:48:12 CDT 2014

Hi, Anthony,

I do some tests on |setup.py|, and notice a strange thing. When I launch 
python and do following tests:

|why at why-XPS-15-9530:~$ python
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.getenv('LD_LIBRARY_PATH')
'/home/why/software/itaps/parallel-shared/lib'
>>>
|

I can get the value of |LD_LIBRARY_PATH| as Ｉ want.

|     @staticmethod
     def _find_defs(iface, path=None):
         if path:
             if os.path.isfile(path):
                 return os.path.normpath(path)
             name = os.path.join(path, iface+'-Defs.inc')
             if os.path.isfile(name):
                 return os.path.normpath(name)
             name = os.path.join(path, 'lib', iface+'-Defs.inc')
             if os.path.isfile(name):
                 return os.path.normpath(name)
             raise Exception("Unable to locate %s-Defs.inc" % iface)
         elif iface.upper()+'_DEFS' in os.environ:
             name = os.getenv(iface.upper()+"_DEFS")
             if os.path.isfile(name):
                 return os.path.normpath(name)
         else:
             # try a bunch of places where iXxx-Defs.inc might be located
             search = [os.path.join(i, '..', 'lib') for i in
                       os.getenv('PATH',  "").split(':') +
                       os.getenv('CPATH', "").split(':')] + \
                      os.getenv('LD_LIBRARY_PATH', "").split(':') + \
                      ['/usr/local/lib', '/usr/lib']
             print search
             print os.getenv('LD_LIBRARY_PATH')
             for i in search:
                 name = os.path.join(i, iface+'-Defs.inc')
                 if os.path.isfile(name):
                     return os.path.normpath(name)
|

That means |setup.py| didn’t find right thing. Is is a bug? Can you give 
me some furthermore hints? Thanks very much.

Best
