heey all, i've tried to embed lua into C++. i'm using this code:


extern "C" {   
#include "lua.h"   
#include "lualib.h"   
#include "lauxlib.h"   
}
#include <stdio.h>
 
int main()   
{   
	int s=0;   
	
	lua_State *L = lua_open();   
	
	luaopen_base(L);
	luaopen_table(L);
	luaopen_io(L);
	luaopen_string(L);
	luaopen_math(L);

	//run a Lua scrip here   
	luaL_dofile(L, "lua/startup.lua");   

	printf("\nI am done with Lua in C++.\n");   

	lua_close(L);   

}

but when i run it i get this error:

Quote:
PANIC: unprotected error in call to Lua API (no calling environment)

any idea's how to solve this error? i'm using: Visual C++ 2008 lua 5.1.4 i'm linking to: lua5.1.lib

I don't know much about lua but...try calling

luaL_openlibs(L);

before

luaopen_base(L);

etc.

maybe it can't find the file. try doing an fopen to that filename and seeing if it succeeds maybe?

Check the first point of this.

Try replacing all your luaopen_* calls with just one to luaL_openlibs.
