Re: [cctbxbb] Boost Import Error

4 Jun 2014

      Thanks Luc,

I have now updated by PYTHONPATH as you suggested:

export PYTHONPATH=/Users/magnus/Downloads/cctbx_sources:/opt/local/bin:/Users/magnus/Downloads/cctbx_build/lib:/Users/magnus/Downloads/cctbx_sources:/Users/magnus/Downloads/cctbx_sources/boost_adaptbx:/Users/magnus/Downloads/cctbx_sources/libtbx/pythonpath:/usr/local/lib

, which indeed makes my /opt/local/bin/python2.7 find boost. However, now I get a new  error message, which is a little harder to interpret:

I don't know how to deal with this - any suggestions?

Thanks,

If you want to do it by hand, you need to parrot what cctbx.python does. You need to set the following environment variables:
1. LIBTBX_BUILD
that must be the path of cctbx_build next to cctbx_sources or cctbx_project
2. PYTHONPATH
at the very least it shall contain $LIBTBX_BUILD/lib:$CCTBXSRC:$CCTBXSRC/boost_adaptbx:$CCTBXSRC/libtbx/pythonpath
where $CCTBXSRC is the full path of cctbx_sources or cctbx_project
3. DYLD_LIBRARY_PATH 
It shall contain $LIBTBX_BUILD/lib
Best wishes,
Luc
