[C++-sig] py++ and indexing_v2

published code rather than commit the project to our own version of boost or add another step to the code generation. Is there a way of telling py++ to use the different namespace and directory? Or am I misunderstanding some things? Thanks for any help James. -- Ring the bells that still can

[C++-sig] Documentation bug

Hi, Trac ticket 1890, 'Missing parameters in example code' looks like a pretty trivial fix, if someone can confirm that it's correct, I'll make the change if no one else can. https://svn.boost.org/trac/boost/ticket/1890 > On the page: > > http://www.boost.org/doc/libs/1_35_0/libs/python/doc/tuto

[C++-sig] boost python to/from python type conversion

Hi, I'm trying to write to/from type converters for my code, and I'm stuck. My case doesn't map well to any of those in the boost python documentation. I'm trying to pass objects of type MPI_Comm (really a C type!) back and forth with mpi4py (which uses cython internally.) The mpi4py author h
