IOS下Libevent编译步骤，及引入Xcode备忘

    0.先用：ls -al /usr/lib | grep libevent 查看是否已安装，如果已安装且版本低于1.3，则先通过：rpm -e libevent —nodeps 进行卸载。
　　
　　1.下载libevent安装包：libevent-2.0.22-stable.tar.gz，然后解压。
　　
　　2.切换到解压后的 libevent 主目录：cd libevent-2.0.22-stable
　　
　　3.依次执行：
　　./configure –prefix=/usr （或 ./configure --program-prefix=/usr）
　　make
　　make install

---lipo

lipo -create /Users/XX/lv/lib/libevent_pthreads.a /Users/XX/build/built/iPhoneOS10.0-arm64.sdk/lib/libevent_pthreads.a -output /Users/xx/lv-all/libevent_pthreads.a

*注意替换路径

生成IOS平台的库文件(libevent_core.a,libevent_extra.a,libevent_pthreads.a)放到$path/ios/libraries中,注意:是IOS的库文件,不是linux的


   头文件放到$path/ios/libevent


  xcode中增加head search path 和 添加刚才的3个库文件
