Hi Roman,
Thanks for the reply - I've had a look at those unit tests, but were
unable to reproduce the same results in my code. I get an error at
import:
"AttributeError: 'Boost.Python.StaticProperty' object attribute
'__doc__' is read-only"
How do I go about running the Py++ unit tests?
As a matter of interest, I'm using Boost 1.42.0, Python 2.6.5, CVS
Head of GCCXML, CVS Head of pygccxml, CVS head of pyplusplus.
In any case, I don't actually have write access to the library I want
to wrap, so I needed another solution.
I'm currently simply excluding those static const int members with
mb.class_('someclass').variable('myvar').exclude()
In that case, the particular class I'm wrapping works fine!
Thanks
Brian
