[pygccxml-development] copy constructor woes

[Lakin W. <lak...@gm...>]

In working some more on the bindings for Ogre, I tried to compile the
following class:
http://lakin.weckers.net/ogre/cpp/Frustum.pypp.cpp

The Frustum class that Ogre defines has a member variable:

VertexData mVertexData;

But VertexData defines a protected Copy constructor.  Now, Ogre
compiles and works fine, because the Frustum class itself doesn't
define a copy constructor, and no code uses the copy constructor, (So
it's not generated by the compiler, iirc).

However, in the generated wrapper, the Copy  Constructor is used, and
then g++ generates the appropriate error:

g++ `pkg-config --cflags OGRE` -I/usr/include/python2.4
-DBOOST_PYTHON_MAX_ARITY=16 -fPIC -Icpp -c -o cpp/Frustum.pypp.os
cpp/Frustum.pypp.cpp

scons: *** [cpp/Frustum.pypp.os] Error 1
scons: building terminated because of errors.

I'm going to file a bug with the Ogre guys, as I'm fairly certain that
they would want to define a copy constructor that works. :)    OGRE's
api and general usage pattern will avoid copy constructors, using and
passing around pointers.  However, that leads to a question:  Is this
also a bug in pyplusplus?
