Hi Magnus,

you need to use the wrappers cctbx.python instead of python as it sets PYTHONPATH correctly so as to add that cctbx_sources/boost.

Best wishes,

Luc

Hi,

I've installed the cctbx package from the selfextracting file found in http://cci.lbl.gov/cctbx_build/ 

but I run into problems when importing cctbx in my python script:

    import iotbx.pdb

  File "/Users/magnus/Downloads/cctbx_sources/iotbx/pdb/__init__.py", line 2, in <module>

    from cctbx.array_family import flex

  File "/Users/magnus/Downloads/cctbx_sources/cctbx/array_family/flex.py", line 2, in <module>

    import scitbx.array_family.flex

  File "/Users/magnus/Downloads/cctbx_sources/scitbx/array_family/flex.py", line 2, in <module>

    import boost.optional # import dependency

ImportError: No module named boost.optional

It is flex.py that wants to import boost.optional and does not find it. 

However, I find these three files:

optional.hpp optional_fwd.hpp optional_io.hpp

in the following directory:

/Users/magnus/Downloads/cctbx_sources/boost/boost/optional

which suggests that it's present. What am I missing here? I'm using Mac OS X Version 10.9.3 and Python2.7.

Cheers,

Magnus
