Ok, here's a distilled code example. Running
python dest.pypp && gcc -c -I/usr/include/python2.6 dest_bindings.cpp
yields the error message
dest.hh:3: virhe: ”virtual A::~A()” is protected
This is with the latest svn version of py++.

Okey. You should use "modify_type" function transformation with "remove_const" type traits function. Untested: from pygccxml import declarations from pyplusplus import module_builder from pyplusplus import function_transformers as FT mb = module_builder_( ... ) f = mb.mem_fun( 'f' ) f.add_transformation( FT.modify_type(0, declarations.remove_const ) ) #0 - argument index HTH -- Roman Yakovenko C++ Python language binding http://www.language-binding.net/ ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig

This does not quite solve the problem, as remove_const will turn "const A" to "A" but leave "A const &" as it is. I modified remove_const to convert "A const &" to "A &" and it is only a few lines. However, I'm not sure whether this really is the semantics you want for remove const. Maybe I should create my own function remove_const_ref and use that as a transformation instead? -- Pertit ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig

Yes you should create and pass your own function. -- Roman Yakovenko C++ Python language binding http://www.language-binding.net/ ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
