Question

i am using CodeBlock on Windows, i have 3 file :

bmp.h

#include <GL/glaux.h>
AUX_RGBImageRec *LoadBMP(char *Filename);

bmp.cpp

#include <windows.h>
#include <stdio.h>
#include <gl/gl.h>
#include <gl/glu.h>
#include <gl/glaux.h>
#include "bmp.h"

AUX_RGBImageRec *LoadBMP(char *Filename)
{
     FILE *File=NULL;
     if(!Filename)
     {
          return NULL;
     }

   File = fopen(Filename, "r");

   if(File)
   {
        fclose(File);

        return auxDIBImageLoad(Filename);
   }

   return NULL;
 }

i am tryng to find solution about -lglu / ld.exe then i cant find anything.

Glass.bmp already on folder, then i try download and copy glaux.dll to MinGW/bin and in my project build linker : opengl32, glu, glut32

Your linker does not know where to find the library you are referencing.

You will have to tell it where to find it. The easiest solution would likely be to add the and the libs directories of the libraries you are referencing to your linker's search directories. Make sure the linker's directories correspond with the build target (in other words don't link x86 and compile to ARM).
