I've tried to merge the Boost.Python tutorials for embedding and extending (see below), to end up with an executable that does both. The script fails to import "hello", so BOOST_PYTHON_MODULE is presumably not the correct way to do it. What is? Thanks, Keith MacDonald ====== The C++ code ====== #include using namespace boost::python; char const* greet() { return "hello, embedded world"; } BOOST_PYTHON_MODULE(hello) { def("greet", greet); } int main() { Py_Initialize(); object main_module(( handle<>(borrowed(PyImport_AddModule("__main__"))))); object main_namespace = main_module.attr("__dict__"); try { handle<> ignored((PyRun_String( "import hello\n" "print hello.greet()\n" , Py_file_input , main_namespace.ptr() , main_namespace.ptr()) )); } catch(error_already_set) { PyErr_Print(); } Py_Finalize(); return 0; } ====== The Jamfile ====== subproject libs/python/example/tutorial/embedded ; # location of the program # bring in the rules for python SEARCH on python.jam = $(BOOST_BUILD_PATH) ; include python.jam ; exe hello # name of the executable : #sources hello.cpp : # requirements <find-library>boost_python <library-path>c:\boost\libs\python $(PYTHON_PROPERTIES) <library-path>$(PYTHON_LIB_PATH) <find-library>$(PYTHON_EMBEDDED_LIBRARY) ;
