[pygccxml-development] beginner questions

[Simon W. <wim...@go...>]

I´m new to py++ and I want to start getting into it by wrapping
micropather, a A* implemantation. It only consists of a header and a
source file so it should be easy to do.
So I used the py++ gui to get the py++ code. Trying to compile it I
got an C2874 error that there is a problem with an operator. I
expected this as in the line above there was an comment:
//WARNING: the next line of code will not compile, because
"::micropather::StateCost" does not have operator== !
So I simply commented out the error line. This leads me to my first
question. How could I have achieved this with py++?
Afterward I get this error:
Fehler	6	error C2248: "micropather::PathNode::~PathNode": Kein Zugriff
auf private Member, dessen Deklaration in der
micropather::PathNode-Klasse erfolgte.	c:\program files
(x86)\boost\boost_1_34_1\boost\python\detail\destroy.hpp	33
How could I sort out that one?
Also I´m confused by another thing.
Trying ou the code from the introduction:
mb.calldefs( access_type_matcher_t( 'protected' ) ).exclude()
I get an errror with:
access_type_matcher_t('protected'). What exactly does this
access_type_matcher_t thingy mean. Looking at the source I get
instructed to look at decl_wrappers.scopdef_t, but that completley
confuses me.

Right now there is a thread that discuss similar problem, on
boost.python mailing list
http://mail.python.org/pipermail/c++-sig/2008-March/subject.html

In order to give better answer source code is needed.

Can you translate the error message to English?

Thanks

'member' : cannot access 'access' member declared in class 'class'

Thanks.

If I understand right, the code doesn't compile because class has
private/protected constructor. In this case Py++ had to place
"no_init" in boost::python::class_ constructor. If this not happens,
than I guess there is a bug here.

P.S. I prefer to see the code and errors, so I could analyze the whole
picture and not to guess.
