C++ OpenGL, errors when linking, compiling

I can't move on with errors from linker, or compiler. I want to compile my old projects, but I can't cope with errors. in folder with source.cpp I have also

open32.dll 
glu32.dll 

glut32.dll (i download it) 
glut.h (si download it) 
glut.lib (i download it) 
glut.def (i think its not nessesery)

bach looks like

path %pathC:\MinGW\bin 
g++ -o program.exe main.cpp glut32.lib

and I get errors in every line where I use function from glut32.dll/opengl.dll, all errors are similar C:\Users\Przemko\AppData\Local\Temp\cc4n2CuY.o:main.cpp:(.text+0xe5): undefined reference to `glClearColor@16'

In MinGW\Include I have folder GL with headers:

glu.h 
gl.h 
glext.h

"i get it while installing MingW"

my source include

#include <time.h>
#include <iostream>
#include <math.h>
#include <windows.h>
#include "glut.h"

I need help, I don't remember how to link every item, I wish I have my old bash and library, but I don't.

You might want to keep your dll files in SysWOW64 folder instead of System32 folder in case you have x64 libraries.

You don't link with the actual OpenGL library, you need to add -lGL to your command:

$ g++ -o program.exe main.cpp glut32.lib -lGL
