Hi to everybody, I'm trying to run an OpenGL program but every time I try to run the following error coming: error LNK2001: unresolved external symbol _auxDIBImageLoadA@4. Thanks for any help. AUX_RGBImageRec *LoadBMP(char *Filename) { FILE *File=NULL; // file handle if (!Filename) return NULL; // make sure there is a file name File=fopen(Filename,"r"); // attempt to read the file if (File) // if file exists, close and return the handle { fclose(File); return auxDIBImageLoad(Filename); //* section of the code is causing error } return NULL; // load failed } // END OF LoadBMP -------------- Yes, I've added all the Headers and Libraries but still not working. #pragma comment( lib, "opengl32.lib" ) #pragma comment( lib, "glu32.lib" ) #define WIN32_LEAN_AND_MEAN #include <windows.h> // include all the windows headers #include <windowsx.h> // include useful macros #include <mmsystem.h> // for mci commands or PlaySound #include <stdlib.h> // for rand functions #include <stdio.h> #include <math.h> #include <gl\gl.h> // OpenGL32 library #include <gl\glu.h> // GLU32 library #include <gl\glaux.h> // GLAUX library #include <glaux.h> [Edited by - Alibaro on August 2, 2005 6:52:34 PM]

The compiler doesn't know what auxDIBImageLoad is. Are you including the proper header or lib?

Yes, I've written all the headers, but may some are missed ?

#include <windows.h> // include all the windows headers
#include <windowsx.h> // include useful macros
#include <mmsystem.h> // for mci commands or PlaySound
#include <stdlib.h> // for rand functions
#include <stdio.h>
#include <math.h>

#include <gl\gl.h> // OpenGL32 library
#include <gl\glu.h> // GLU32 library
#include <gl\glaux.h> // GLAUX library

Never really used GLaux but I'm guessing you still need link to the library from the error

I've spent more than a week for searching and finally I've got nothing.

So, please if anyone know how to solve this problem or know any useful sites.Tell me soon. Thanks for any help.

Thanks a lot to Everybody, My program is working very fine now, Thank you again.
