Hi, All, I've got a build error in Mac OS X 10.5. Configure string is below. ./configure --disable-mplayer --disable-gui --enable-runtime- cpudetection --disable-network --disable-inet6 --disable- gethostbyname2 --disable-ftp Though I tried the only --disable-network and had the same result: Undefined symbols: "_ff_socket_nonblock", referenced from: _tcp_open in libavformat.a(tcp.o) _udp_open in libavformat.a(udp.o) "_closesocket", referenced from: _tcp_close in libavformat.a(tcp.o) _tcp_open in libavformat.a(tcp.o) _tcp_open in libavformat.a(tcp.o) _udp_open in libavformat.a(udp.o) _udp_close in libavformat.a(udp.o) ld: symbol(s) not found collect2: ld returned 1 exit status make: *** [mencoder] Error 1 Could anybody tell me how to fix this problem? BTW, I tried to build mplayer/mencoder after empty configure, and had none of errors. -Alex
