[C++]Compiling a library with GCC

[Metin2 Dev 4698]

Good Day!
I'm trying to build a simple "hello_world" like functions, for LUA's quests.

That's the error:
Compiling questlua_global.cpp

I'm using the TheGame BSD and i've followed this guide Denic Cikiec

 

I'm using this command:

gcc -shared -o -libprova.so -fPIC -questlua_global.cpp

Thx!

you need to include lua.h

Thx

 

Now i've got this error: std::string
I think that i need to work a little bit on paths, because some headers includes other headers but with a wrong path.

Like lua_incl.h that uses #include <lua.h> changed to #include "lua.h" and now it works

 

---UPDATE!---

replacing GCC with G++ it works (90% works), now it says:
