It seems we have two issues here. First there's this: "socket.c:1124:40: error: 'IPV6_V6ONLY' undeclared (first use in this function)" The above error can be fixed by using mingw-w64 that is recent enough - version 2.23 seems to work fine. However, that will not fix this error: socket.c: In function ‘socket_bind’: socket.c:1120:7: warning: passing argument 4 of ‘setsockopt’ from incompatible pointer type [enabled by default] if (setsockopt(sd, IPPROTO_IPV6, IPV6_V6ONLY, &v6only, sizeof(v6only))) ^ In file included from ../../src/compat/compat.h:29:0, from syshead.h:28, from socket.c:31: /usr/share/mingw-w64/include/winsock2.h:999:34: note: expected ‘const char *’ but argument is of type ‘int *’ WINSOCK_API_LINKAGE int WSAAPI setsockopt(SOCKET s,int level,int optname,const char *optval,int optlen); ^ socket.c: In function ‘socket_recv_queue’: socket.c:3098:45: error: ‘struct link_socket_addr’ has no member named ‘local’ int addrlen = af_addr_size(sock->info.lsa->local.addr.sa.sa_family); ^ make[4]: *** [socket.o] Error 1 - --- The above can be reproduced using latest Git sources and Ubuntu 14.04. Any ideas how to fix this?
