Lua help

[Ewan]

Well, yet again my linker's giving me crap. I've downloaded the source code for this tutorial: http://www.gamedev.net/reference/progra ... efault.asp (thanks M_D_K). I'm linking to lualib.lib and lualib_dbg.lib, and in my Search Directories I have lib and include, in compiler and linker respectively.

Running this

Code: Select all

#include <lua.h>

int main(int argc, char* argv[])
{
	lua_State* L = lua_open(0);
	lua_close(L);
	return 0;
}

gives me undefined references to both lua functions.

obj\Debug\main.o||In function `main':|
C:\Documents and Settings\Ewan\Desktop\Code Blocks\luatest\Lua\main.cpp|5|undefined reference to `lua_open(int)'|
C:\Documents and Settings\Ewan\Desktop\Code Blocks\luatest\Lua\main.cpp|6|undefined reference to `lua_close(lua_State*)'|
||=== Build finished: 2 errors, 0 warnings ===|

The guy in the tut says to use extern "C" around your includes but that just gives me a bunch of DIFFERENT errors..

Code: Select all

extern "C"
{
    #include <lua.h>
}

int main(int argc, char* argv[])
{
	lua_State* L = lua_open(0);
	lua_close(L);
	return 0;
}

Any help would be greatly appreciated

You have to put quotes around lua.h instead of brackets.

Thanks, I figured that out but now I get this:



"The application has failed to start because MSVCR90.dll was not found. Re-installing the application may fix this problem."

Any clues?

Edit: I'm guessing it's something to do with the fact that I compiled the Lua libraries with VS, because when I downloaded them they were in VS project form..

You need the M$-C-Runtime-Library. Isn't it included with VS? Sorry, I can't give you further information cause I don't use VS (gcc ). Maybe it is because you didn't create the project yourself. Look for the dll in the Windows-directory.
If you can't find it you can download it from here.
Or create a new project and copy the code.

Thanks, I've now got the compiled libraries for Windows from the Lua site and it seems to be working fine.
