Unfortunately, GCCXML doesn't provide information about function
implementation and arbitrary C/C++ expression. So Py++ can't see this

Because what you think is good for you is actually bad for me( and
other users who already use Py++ ).
The assumption has a simple background( at least in my case ): in most
cases the project dependencies are bigger( more code ) than the
project itself. So it should be much easier to define what to export,
then the opposite. You can argue with this, but this is the current
default behavior and it is not going to change.
I understand that your use case is different than my - fine. I believe
Py++ has all functionality you need, to define what declarations
should be exported. Consider to use "reverse"logic:
mb = ctypes_module_builder_t( ... )
#and now define what you want to include
May be you should take a look on
"module_builder/ctypes_decl_dependencies.py" module. It contains
"find_out_dependencies" functionality. As input it takes a set of
declarations you want to expose, the output is a set of all classes,
that need to be exposed.
