mingw 環境編譯eXosip2-3.6.0 故障解決

環境:mingw gcc 4.5.2

exosip2-3.6.0

osip2的編譯過程就不說了，下面直接進正題，解決以下錯誤：

eXtl_udp.c:181:3: error: 'retval' undeclared (first use in this function)
eXtl_udp.c:181:3: note: each undeclared identifier is reported only once
for each function it appears in

好了，遇到這些問題，大家應該和我剛開始遇到一樣，有點發暈了吧，直接上patch

retval未定義，這個簡單吧：

接下來下面的編譯過程就很順利了：

編譯 exosip2-3.6.0

#export LIBS='-lws2_32-lwsock32 -liphlpapi -ldnsapi -lssl32 -lcrypto -lpthread'

# ./configure --enable-openssl --enable-pthread --prefix=/usr/local/exosip2/

#make

#make install
