linux添加头文件路径

gcc demo.c -o demo? -I/tools/libevent/include -L/tools/libevent/lib -levent

-I：头文件目录

-L:静态库目录

-l:静态库名字

如果想简单点，就在/etc/profile添加

29 C_INCLUDE_PATH=/tools/libevent/include:$C_INCLUDE_PATH
30 export C_INCLUDE_PATH
31
32 LIBRARY_PATH=/tools/libevent/lib:$LIBRARY_PATH
33 export LIBRARY_PATH

reboot后??gcc demo.c -o demo? -levent就可以了
