ifferent, and don't
have operator== to compare their referents (at least that's my guess about
what's going on). Is there something else I can use instead of bp::ref here
that will cause the list items to "point to" the same param ea
rked at all.
Whoa, that is cool! I had no idea boost python could do this. Thanks, Stefan!
(It's like "python-ception": python calls C++ which calls python...)

least I think I
should be able to - but I'm not sure how far the boost.python world goes).

So now it returns a python list of python dicts. All I want now is to override
__getattr__ on each ppinfo dict so it returns the dict value as the attribute
value, so in python I can reference effect_list[i].name instead of
effect_list[i]['name']. O

Thanks Jim; if that's happening, something on the python side must be eating
that exception, because I don't see it there. Still, this is a complex piece
of code so it's entirely possible it is being swallowed on the python side.
I'll co
_name(cpp_args)
That's exactly what I'm trying to figure out! The c++ exception gets handled
in handle_exception and it never gets turned into a python exception as far as
I can tell.

there is all this logic
in the boost::python call framework to build nice error messages about which
overloads were tried, but that message never comes out anywhere.

since my function never gets called (the argument error is detected by
boost.python). What ends up happening is it just silently fails.
What can I hook up so I (or my users) can see the argument error messages? And
ideally convert those into python exceptions?
This is all Win7, Python2.7.

I recently posted an issue on StackOverflow about some Py++-generated code that
didn't seem to work. The question is at
http://stackoverflow.com/questions/19461274/.
Simply, I have these classes:
struct classA {
int intval;
unsigned int bitfield_member:1;
};
struct Collection {
classA *
Hi folks; I hope someone can help with a problem I'm having.
I have Base and Other classes (sorry for the generic names), and Base contains
a fixed-length const array of pointers to Others. I'm trying to expose Base to
python. I started with a pyplusplus run and hand-massaged the result, so it
about exporting
that particular field to python; can I tell pyplusplus to ignore it somehow?
That struct does get used lots of other places though, if that matters.

SCons FTW! :-)
I built from source and tried it all again with bjam; no luck, same problems.
So I figured, how hard can it be, it's just a DLL after all (renamed to .pyd).
And sure enough it's not that hard. Here's a SConstruct that builds the
tutorial example, wherever it is (does not have to
g") but I guess extending is
similar, just make a DLL project and rename the output or something maybe?

on at this point.
I did download the source distribution, but it doesn't have a Jamfile in its
root dir either. Maybe I have to unpack it and run b2 to get that... I guess
I'll try that next.

newbie questions come from not doing that.
In any case, I can use bjam to build and test the tutorial example when it's
inside the boost tree, but not when I move it outside -- I feel like I must be
missing something simple.
