0x01 編譯錯誤

編譯錯誤 1

make
gcc -Os -Wall -c  -fPIC -I../lua/src -c LuaXML_lib.c
LuaXML_lib.c:36:17: 致命錯誤：lua.h：沒有那個檔案或目錄
 #include <lua.h>
                 ^
編譯中斷。
make: *** [LuaXML_lib.o] 錯誤 1

伺服器上lua的狀態

[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檔案，將標頭檔案和庫檔案的目錄換成系統中lua標頭檔案和庫檔案所在的目錄。

查詢標頭檔案 find / -name "lua.h" ，顯示在
/usr/local/openresty/luajit/include/luajit-2.1/lua.h

查詢庫檔案 find / -name "liblua*.a"，顯示在
/usr/local/openresty/luajit/lib/libluajit-5.1.a

編譯錯誤 2

make，這裡可能會提示找不到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: 錯誤：ld 返回 1
make: *** [LuaXML_lib.so] 錯誤 1

在伺服器上繼續找，找到了
/usr/lib64/liblua-5.1.so
 

0x02 最終 Makefile

檔案如下
