Linux之libevent的編譯&測試__Linux

1.下載
http://download.csdn.net/detail/sauphy/9314091


2. 編譯
./configure --prefix=/opt/libevent
make
make install


3. 開發編譯
gcc test_signal.c -o ok -I/opt/libevent/include -L/opt/libevent/lib -levent
./ok


3-1、串連出錯：
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. 運行
./ok

Ctrl+C 運行（顯示兩個訊號）
