Subject: Problem wrapping the C++ STL

Hi all,

Is it possible to wrap the C++ STL stuff? Say, for example, vector?

#include "ruby.h"
#include <vector>
using namespace std;

struct cvector{
    vector<VALUE> array(0);
};

void Init_cvector(){
    VALUE cVector = rb_define_class("CVector", rb_cObject);
}

When I try to compile this (using g++ on OS X) I get:

/usr/local/lib/ruby/1.8/i686-darwin8.9.1/intern.h:207: error: use of 
enum 'rb_thread_status' without previous declaration
/usr/local/lib/ruby/1.8/i686-darwin8.9.1/intern.h:207: error: invalid 
type in declaration before ';' token
cvector.c:6: error: expected identifier before numeric constant
cvector.c:6: error: expected ',' or '...' before numeric constant
cvector.c: In function 'void Init_cvector()':
cvector.c:10: warning: unused variable 'cVector'
make: *** [cvector.o] Error 1

Thanks,

Dan
