error in usin list with boost

[GujuBoy]

i have created a "cpp" file which has the followin code and when i try
to compile it..it does not know what "list" is..it says its
undefined..i also tried using #include <boost/python/list.hpp>

but no differe...can someone please help.

thanks

static list retrieval_as_list(SplitText &self, int position,
int retrieveLength) {
list result;

int *characters = new int[retrieveLength];
int lenRet = self.RetrieveUTF32(position, characters,
retrieveLength);
for (int i=0;i<lenRet;i++) {
result.append(characters);
}
delete []characters;
return result;

}

If I'm not completely mistaken: you know that this usage should (at least
under all sensible terms) allocate a list on the stack and thus local to the
function and not on the heap, unless boost does some mumbo jumbo that I know
nothing of like starting the list with refcount=2? I don't think that's what
you want...

But for your boost usage, I have absolutely no idea! Why not write the Python
wrapper directly in C? Just as easy, probably. And from what my experience is
with using SWIG and SIP: much less errorprone...

I would have expected this (except the cstdint.h line which may not
be needed but it was in the code I copied from) to already be in your
code if you are using Boost Python:

#include <boost/python.hpp>
#include <boost/cstdint.hpp>
using namespace boost:ython;
