在lua中用下面这种方式使用socket，安装luasocket-2.0.2后老是报一些莫名其妙的错误。

require("socket")

下面是部分报错信息

lua: error loading module 'socket.core' from file '/usr/local/lib/lua/5.3/socket/core.so':
    /usr/local/lib/lua/5.3/socket/core.so: undefined symbol: luaL_checkint

在网上找了一篇博文写的不错，博文地址 ,但是按照博文修改源码后依然不能解决问题

又Google了一篇文章写的更好，从根本解决上解决了问题博文地址 感谢！

顺便在luajit-2.0.4(生产环境版本)试了一下第二种方式，在编译时会报错如下

luasocket.c:18:17: fatal error: lua.h: No such file or directory
compilation terminated.
<builtin>: recipe for target 'luasocket.o' failed
make[2]: *** [luasocket.o] Error 1
make[2]: Leaving directory '/tmp/luasocket/src'
makefile:359: recipe for target 'linux' failed
make[1]: *** [linux] Error 2
make[1]: Leaving directory '/tmp/luasocket/src'
makefile:18: recipe for target 'linux' failed
make: *** [linux] Error 2

问题原因是make时找不到lua.h头文件，编译时自己手动指定头文件路径LUAINC=/usr/local/luajit/include/luajit-2.0，如下

make LUAINC=/usr/local/luajit/include/luajit-2.0
make install
