I have a C++ function I want to call from sage. I have attempted to
follow the example in
http://docs.cython.org/src/userguide/wrapping_CPlusPlus.html
This was unsuccessful. The C++ class is not recognised. The problem
seems to be that this is Cython v0.13 whereas sage 4.5.2 (which I am
using) and sage 4.5.3 uses Cython v0.12.
If this is correct the options seem to be to use cython v0.12 (in
which case I don't have documentation) or to upgrade to cython v0.13
(which I don't know how to do).
Here is how I tried to read in my C++ header file:
cdef extern from "/home/masdbn/planargraph/Graph.hpp" namespace
PlanarGraph:
cdef cppclass Graph:
pass
Where do I go from here? Thanks
