I have a DLL written in D I load into a Python application via ctypes like so:lib = CDLL("mydll") The DLL loads and can be used no problem. However, once the DLL is discarded of by the program, the program either doesn't react or crashes. I still haven't worked out how to clean up the DLL correctly before it is unloaded / detached (from Python). I guess it's the GC and/or some C stuff I've overlooked. I have tried both approaches described on this page: http://dlang.org/dll.html. Maybe someone of yous once had a similar problem and found a solution. Any hints or suggestions would be appreciated. Thanks.
hmm. pyd uses the example under 'DLLs with a C Interface' for its windows dll code and it seems pretty stable, but then it doesn't use ctypes. It doesn't look like you need to be mucking with rt_init and rt_term, so maybe the garbage collector is trying to collect something that python still has a reference to?
Also, if you can finagle a dll out of gdc I would love to hear about it. I have not used it on windows, though.
