[Opensg-users] OpenSG Python Bindings

[Venkat (O. <op...@na...>]

Hello,

 
I want to know how I can build the python bindings for latest opensg from git.

 
I tried to build using the pyopensg project and I get the following error:

Generating the bindings using pygccxml on linux fails with the following error:

 
Traceback (most recent call last):

IOError: [Errno 2] No such file or directory: '/data/src/opensg-py/build/Python/OSGContribWebInterface/module/generated/osg_exported.txt'

 
In addition, on Mac OS X 64 bit, I get the following errors:
