luasocket编译安装遇到的坑

由于需要获得本机的IP地址，所以需要 ：

local socket = require('socket')
local server_hostname = socket.dns.gethostname()
local server_ip = socket.dns.toip(server_hostname)

需要下载源码编译：luasocket-2.0.2.tar.gz

- 解压好之后首先修改config文件来制定安装的路径，修改涉及的三个地方：

# 由于是先安装的openresty-1.13.6.1：/opt/soft/openresty/
LUAINC=-I/opt/soft/openresty/luajit/include/luajit-2.1/
INSTALL_TOP_SHARE=/opt/soft/openresty/luajit/share/lua/5.1
INSTALL_TOP_LIB=/opt/soft/openresty/luajit/lib/lua/5.1

- 编译安装

make
make install 

 cd src; make all
 make[1]: Entering directory `/data/tools/luasocket-2.0.2/src'
 gcc -I/opt/soft/openresty/luajit/include/luajit-2.1/ -DLUASOCKET_DEBUG  -pedantic -Wall -O2 -fpic   -c -o luasocket.o luasocket.c

查找luaL_reg

/opt/soft/openresty/luajit/include/luajit-2.1/lauxlib.h 里定义的结构体名字和 luaL_reg 不一致

 typedef struct luaL_Reg {
   const char *name;
   lua_CFunction func;
 } luaL_Reg;

然后把 luasocket-2.0.2/src 下所有luaL_reg 替换成 luaL_Reg ，

然后重新编译就可以了。
