Hi Hesham, it looks like you do not link with WinSock, add ws2_32.lib and/or wsock.lib or something like that. It should be first link in google. Cheers - Vali PS. Benny, in case you read this conversation, aren't you interested in applying suggested patch to be able to build PJSUA using pjsua_lib.dll easily?
