Cannot use UDP sockets: unresolved external symbol #76

Open goldeneas opened 1 year ago

goldeneas commented 1 year ago

When I try to create an UDP socket using this library an unresolved external symbol errors pops up. However this does not happen if I try to create a TCP socket. What should I do?

Perhaps it would be helpful if you show us the error.

OK. It's better if you paste in the text of the sample and error(s) rather than adding an image or a link.

So a trivial UDP example (on Windows x64) that creates and binds an IPv4 UDP socket is complaining that sockpp::datagram_socket::create_handle(int, int) is missing.

That's odd... the function is completely defined in the header: https://github.com/fpagliughi/sockpp/blob/f3100f575b38e83a1f2464ca54228bebb1282679/include/sockpp/datagram_socket.h#L76-L78

Plus this same idea is implemented in the UDP echo server example which, last I checked, compiles and run fine on Windows. https://github.com/fpagliughi/sockpp/blob/f3100f575b38e83a1f2464ca54228bebb1282679/examples/udp/udpechosvr.cpp#L91-L100

So far, I can't think of what would cause this, but I can test it from a stand-alone app to see if it does anything weird.
