    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) ?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    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.
