0x01 编译错误

编译错误 1

make
gcc -Os -Wall -c  -fPIC -I../lua/src -c LuaXML_lib.c
LuaXML_lib.c:36:17: 致命错误：lua.h：没有那个文件或目录
 #include <lua.h>
                 ^
编译中断。
make: *** [LuaXML_lib.o] 错误 1

服务器上lua的状态

[root@iZ255h7jx9sZ luaxml-master]# which lua
/usr/bin/lua
[root@iZ255h7jx9sZ luaxml-master]# lua -v
Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio

需要修改其中的Makefile文件，将头文件和库文件的目录换成系统中lua头文件和库文件所在的目录。

查找头文件 find / -name "lua.h" ，显示在
/usr/local/openresty/luajit/include/luajit-2.1/lua.h

查找库文件 find / -name "liblua*.a"，显示在
/usr/local/openresty/luajit/lib/libluajit-5.1.a

编译错误 2

make，这里可能会提示找不到llua
也需要修改Makefile

[root@iZ255h7jx9sZ luaxml-master]# make
gcc -Os -Wall -c  -fPIC -I/usr/local/openresty/luajit/include/luajit-2.1/ -c LuaXML_lib.c
gcc -o LuaXML_lib.so -fPIC -shared LuaXML_lib.o -L. -L../usr/local/openresty/luajit/lib/  -llua -ldl 
/usr/bin/ld: cannot find -llua
collect2: 错误：ld 返回 1
make: *** [LuaXML_lib.so] 错误 1

在服务器上继续找，找到了
/usr/lib64/liblua-5.1.so

0x02 最终 Makefile
