My code currently reads: #include <iostream> #include "./include/Python.h" #include "./boost/python.hpp" using namespace boost::python; int main(void) { Py_Initialize(); object main_module = import("__main__"); object main_namespace = main_module.attr("__dict__"); object ignored = exec("print Hello world",main_namespace); return 0; } The program links successfully and begins running, however an access violation occurs (NULL pointer) at the first line after "py_initialize();" when i call import("__main__"); Visual studio 2010s debugger says the exception occurs at: line 74 in object_attributes.hpp: inline object const_attribute_policies::get(object const& target, char const* key) { return python::getattr(target, key); } Python was built using Visual studio 2010 so i had access to the python debug library. Boost is version 1.45 and was built using : bjam --build-type=complete msvc stage --with-python I am linking against: boost_python-vc100-mt-gd-1_45.lib and boost_python-vc100-mt-gd-1_45.dll I have looked for soutions on the internet and have found nothing right now. Can anyone help me? note: i am building my application in MSVC 2010, this should work though shouldn't it?
