Well, there's no mention of another librarary, and "import _SHIP" is the first (non-comment) statement in SHIP.py But when I run Dependency Walker against _SHIP.pyd it does say there's a missing DLL (WINUSB.DLL) so I suspect I've got to sort that out. >> >> >> Can anyone offer me any suggestion where I am going wrong or how to >> tackle >> this problem? >> >> >> >> Could it be that the Python 2.6 I am running did not use the same >> compiler >> (VC6) with which I buiult _SHIP.pyd and if so, is there a way round this >> without moving on from VC6? >> > > Shouldn't be a problem, as long as the calling convention hasn't change, > which it hasn't.
