[Visualpython-users] compiling under OS X

[Brad M. <bon...@ma...>]

Hello,

I've been trying to get visual-3.1.1 to compile using the natively  
installed version of python under 10.3.8.
I run into this compiler error when compiling frame.cpp.

/opt/local/include/boost/python/object/py_function.hpp:38:    
instantiated from `PyObject*  
boost::python::objects::caller_py_function_impl<Caller>:: 
operator()(PyObject*, PyObject*) [with Caller =  
boost::python::detail::caller<visual::shared_vector&(visual:: 
Primitive::*)(), boost::python::return_internal_reference<1,  
boost::python::default_call_policies>,  
boost::mpl::vector2<visual::shared_vector&, visual::frame&> >]'
/opt/local/include/boost/python/slice_nil.hpp:60:   instantiated from  
here
/opt/local/include/boost/python/detail/wrapper_base.hpp:64: error:  
cannot
    dynamic_cast `x' (of type `const volatile class  
visual::shared_vector*') to
    type `const volatile class boost::python::detail::wrapper_base*'  
(source
    type is not polymorphic)

In looking at the Boost FAQ  it appears that this may be a known  
problem with the gnu compiler on the mac.  There is a cryptic  
workaround suggested, but I've tried that as best I can with no luck.

Any suggestions, or should I just accept that I will need to use the  
fink version under X11?

Thanks,

Brad
