hi I followed the basic boost python examples, both hello_ext.greet() and hello.World() and both are giving me AttributeError error, like AttributeError: module `hello` has no attribute 'greet' dumpbin does show that I have PyInit_hello exported out. Please let me know if I am doing something wrong as this should be trivial. thx -- Any MicroSoft extension file will directly go to trash without any warning and regret.
