Conda OSX loading problems #45

Closed rainman110 closed 7 years ago

rainman110 commented 7 years ago

The smesh conda packages cannot be loaded by python. The _SMESH package cannot be imported, as the libraries are not properly fixed up.

The error are similar to:

Traceback (most recent call last):
  File "/Users/martin/Documents/miniconda/envs/pythonocc-nightly/lib/python3.6/site-packages/OCC/SMESH.py", line 18, in swig_import_helper

You should enable binary relocation of use install_name_tool to fix these problems.

The issue is fixed as of 672518002ae650ff6666eb5e3c93d5a2f3ab9bc6. We just need a recent conda package and compile pythonocc again against smesh.
