1.下载 http://download.csdn.net/detail/sauphy/9314091 2. 编译 ./configure --prefix=/opt/libevent make make install 3. 开发编译 gcc test_signal.c -o ok -I/opt/libevent/include -L/opt/libevent/lib -levent ./ok 3-1、连接出错： error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory A1、 ln -s /opt/libevent/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5 4. 运行 ./okCtrl+C 运行（显示两个信号）
