Hi All I'm trying to embed the python interpreter in a C++ program so that users can write simple scripts that can be executed when the program runs. I've been following the "Using the the Interpretter" examples an dhave had quite a lot of success, except with this one: handle<> main_module(borrowed( PyImport_AddModule("__main__") )); handle<> main_namespace(borrowed( PyModule_GetDict(main_module.get ()) )); handle<> main_module( borrowed( PyImport_AddModule("__main__") )); main_namespace dict(handle<>(borrowed( PyModule_GetDict(main_module.get ()) ))); handle<>( PyRun_String(" result = 5 ** 2", Py_file_input, main_namespace.ptr(), main_namespace.ptr()) ); int five_squared = extract<int>( main_namespace["result"] ); I'm using boost 1.30.0 and MSVC 7.1, along with the following warning (?!!): builtin_converters.hpp(114) : warning C4267: 'argument' : conversion from 'size_t' to 'int', possible loss of data I get the following errors: error C2146: syntax error : missing ';' before identifier 'dict' error C2039: 'ptr' : is not a member of 'boost::python::handle<>' error C2039: 'ptr' : is not a member of 'boost::python::handle<>' error C2676: binary '[' : 'boost::python::handle<>' does not define this operator or a conversion to a type acceptable to the predefined operator The "missing ';' before identifier 'dict'" error I can understand and I ppear to be able to fix by swapping "main_namespace" for "handle<>". I can also fix the "'ptr' : is not a member of 'boost::python::handle<>'" error by changing ptr to get. However, the final error has me stumped. Any suggestions appreciated.
