Looks like you need to link against the winsock library (Ws2_32.lib). tim

I have writed a python expanded in winxp with mingw+msys compiled.It will call libevent lib.I hope that user don't install more library,so I want to compile it statically.But there are some error.I describe the process. compile and install libevent: ./configure -prefix=D:/libevent -enable-static make make install makefile 1: HEAD_PATH_FLAGS=-IC:/Python27/include -ID:/boost/include/boost-1_52 -ID:/libevent/include LIB_PATH_FLAGS=-LD:/boost/lib -LD:/libevent/lib -LC:/Python27/libs LIB_FLAGS=-lboost_python-mgw46-s-1_52 -Wl,Bstatic -levent -Wl,Bdynamic -lpython27 -lwsock32 SOURCE=test.o all:${SOURCE} g++ ${HEAD_PATH_FLAGS} ${SOURCE} ${LIB_PATH_FLAG} ${LIB_FLAGS} -fPIC -shared -o test.dll makefile 2: HEAD_PATH_FLAGS=-IC:/Python27/include -ID:/boost/include/boost-1_52 -ID:/libevent/include LIB_PATH_FLAGS=-LD:/boost/lib -LD:/libevent/lib -LC:/Python27/libs LIB_FLAGS=-lboost_python-mgw46-s-1_52 -lpython27 -lwsock32 SOURCE=test.o D:/libevent/lib/libevent.a all:${SOURCE} g++ ${HEAD_PATH_FLAGS} ${SOURCE} ${LIB_PATH_FLAG} ${LIB_FLAGS} -fPIC -shared -o test.dll I have writed two makefile and do the same error. libevent.a(buffer.o):In function 'evbuffer_read':undefined reference to 'WSARecv@28' libevent.a(buffer.o):In function 'evbuffer_write_iovec':undefined reference to 'WSASend@28' ........................ Why?How to compile it rightly.
