#include issue, " 'foo()' was not declared in this scope"

Question

Yesterday I wrote a simple program. The problem is that g++ won't compile it -

main.cpp: In function ‘void display()’:
main.cpp:32:21: error: ‘loadObj’ was not declared in this scope
  loadObj("model.obj");

I don't understand why - everything has been included. I'm trying to build it with this command

g++ -Wall -o main objLoader.cpp main.cpp -lGL -lglut -lGLU

There is a link to source: CLICK

Any ideas?

@chris is right! It has exactly the same issue as stated in the dupe: `#ifdef __OBJLOADER_H_INCLUDED__` — πάντα ῥεῖ, Jul 03 '14 at 14:15

@πάνταῥεῖ I'd never think that i screwed up guards, so i didn't search any mistake there :) Anyway thanks for help guys. — Gogetek, Jul 03 '14 at 14:30

Your include guards in ObjLoader.h are wrong.

#ifdef __OBJLOADER_H_INCLUDED__

should be

#ifndef __OBJLOADER_H_INCLUDED__

Note the n after the if. As it currently stands, the contents of the header are always ignored by all source files.

Change your safe guards in your objLoader.h to:

#ifndef __OBJLOADER_H_INCLUDED__

#ifdef is "if defined" which obviously is not.
