This seems to work:
#include <boost/python.hpp>
#include <iostream>
namespace bp = boost::python;
void myfunction() {
std::cout << "Hello world!\n";
}
int main(int argc, char* argv[]) {
Py_Initialize();
bp::object main = bp::import("__main__");
bp::object global = main.attr("__dict__");
bp::object function = bp::object(myfunction);
global["function"] = function;
bp::exec("function()", global, global);
return 0;
}
Is this what you wanted?
Boost python's def returns void, which is natural I think, since you
can't assign to the "result" of def in python either.
Hope this helps,
Thomas
