#2089: liblwgeom cannot be used through python ctypes
 Reporter:  brushtyler  |       Owner:  pramsey      
     Type:  defect      |      Status:  new          
 Priority:  medium      |   Milestone:  PostGIS 2.1.0
Component:  liblwgeom   |     Version:  trunk        
 Keywords:              |  
 I'm trying to access liblwgeom functionalities through python ctypes, but
 I get an error because lwgeom_init_allocators is not defined.

 >>> ctypes.cdll.LoadLibrary("/usr/local/lib/liblwgeom.so")
 Traceback (most recent call last):
     self._handle = _dlopen(self._name, mode)
 OSError: /usr/local/lib/liblwgeom.so: undefined symbol:

 In fact programs want to use the library must define
 lwgeom_init_allocators() function.
