Lua library linking issue

[CBradford]

Hi, I've wasted the entire day trying to get the Lua library lua52.lib linked to my C++ project in Code Blocks.
I'm at a loss as to what is wrong. I have the .lib file in C:\MinGW\lib. I have the header cLua.h in C:\MinGW\include.
The .lib file is specified in the Link Libraries list in Build options. I (of course)  #include "cLua.h" in my project.
The directories for library and include are specified in "Search Directories" for the compiler.

Whenever I try to create a new instance of the cLua class from cLua.h

Code

cLua *pLua = new cLua;

the following error appears during the linking stage:

Code

undefined reference to `cLua::cLua()'

I'm trying to figure out what I've overlooked here. This library just refuses to link no matter what. Please help. Going insane here


Edit: I should note that other libraries such as SDL have linked just fine.

The .lib extension is NOT correct for MinGW GCC/Code::Blocks Static Library.

If it is a real MinGW GCC Static Library rename it with .a extension.

I forgot to mention I've also tried it with .a format library files as well.

Turn on Full Compiler Logging and post the Build Log, of a Re-Build, where someone who uses Lua can see it.
No idea, if an Lua users are on Code::Blocks.

Yeah this may be more a Lua issue. But im really not sure.
At this point I've tried just about everything. I even built Lua from source with the proper mingw commands in the make file. same thing.

I'm using the header file cLua.h. This inits Lua. Could this be the problem?
Is there a definitive way to test and see if a library is linking properly?

cLua.h:

Code

#ifndef __CLUA__
#define __CLUA__

struct lua_State;

#define LuaGlue extern "C" int
extern "C" {
typedef int (*LuaFunctionType)(struct lua_State *pLuaState);
};

class cLua
{
public:
	cLua();
	virtual ~cLua();

	bool		RunScript(const char *pFilename);
	bool		RunString(const char *pCommand);
	const char *GetErrorString(void);
	bool		AddFunction(const char *pFunctionName, LuaFunctionType pFunction);
	const char *GetStringArgument(int num, const char *pDefault=NULL);
	double		GetNumberArgument(int num, double dDefault=0.0);
	void		PushString(const char *pString);
	void		PushNumber(double value);

	void		SetErrorHandler(void(*pErrHandler)(const char *pError)) {m_pErrorHandler = pErrHandler;}

	lua_State	*GetScriptContext(void)		{return m_pScriptContext;}

private:
	lua_State	*m_pScriptContext;
	void(*m_pErrorHandler)(const char *pError);
};

#endif

yeah I figured out what it is. I'm using the cLua.h header which actually utilizes a custom Lua library, not the standard release one. doh. Now the hard part is getting that to work.
