AUX_RGBImageRec Function error. HELP!

So i have my class that will handle graphic for my game:

Code:

class Graphic
{
public:
	GLuint *Texture;
	int TextureAmount;
	vector<char*> ImageName;

	Graphic();
	Graphic(int textureAmount);
	~Graphic();

	bool LoadInformation ( char* fileName );	// load the file that contains direction of the images will be load

	AUX_RGBImageRec *LoadBMP(char *fileName);	// load bitmap images from external file

	bool LoadTextures();
};

Code:

AUX_RGBImageRec *Graphic::LoadBMP(char *fileName)
{
	FILE *file = NULL;			//file handle

	if ( !fileName )		//make sure the file name is given
		return NULL;		//if not, quit the function

	file = fopen(fileName, "r");		//check to see if the file exist

	if ( file )
	{
		fclose(file);		//close the handle
		return auxDIBImageLoad(fileName);       // Load The Bitmap And Return A Pointer
	}

	return NULL;		//if fail to load, then return null

}

Then after implement the AUX_RGBImageRec() function, I got an external error and dont know how to solve it.
Error:

Code:

Graphic.obj : error LNK2019: unresolved external symbol _auxDIBImageLoadA@4 referenced in function "public: struct _AUX_RGBImageRec * __thiscall Graphic::LoadBMP(char *)" (?LoadBMP@Graphic@@QAEPAU_AUX_RGBImageRec@@PAD@Z)

Can someone point out what i did wrong. Thank you very much

Missing library on the linker command line?

Incorrect spelling of function name (say capitalisation) ?

I checked all of these already, doesnt seem to be those issuses though.

I think you should check again, make sure you're know which library has auxDIBImageLoad. It's a linker error, so it has to do with a missing library.

Once, I had a linker error because my code was confused about the return value of a function. I was looking for the function that returned an int, but it was determined to use the one that returned a float. static_cast'ing the function fixed that. Worth a shot if you're certain you have all the correct libs.
