GL/glut.h no such file or directory

The things I did are

1. After installation of MinGW i have added the Path to the path enviornment variable
2. Added 'glut.h' to C:\\MinGW\\Include\\GL
3. Added glut32.dll to C:\\Windows\\SysWOW64
4. Added glut32.lib to the project folder
5. COmpiled with 'g++ -o hello.exe -Wall hello.c glee.lib glut32.lib -lopengl32 -lglu32'

and still the error above persist please help

#include<GL/glut.h>
#include<iostream>
//#include<conio.h>

void render(void);

void keyboard(unsigned char c, int x, int y);

void mouse(int button, int state, int x, int y);

int main(int argc, char** atgv)
{
glutInit(&argc, argv);
glutInitDisplayMode( GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
glutInitWindowPosition(100, 100);
glutInitWindowSize(640, 480);
glutCreateWindow("Sample GLUT Application");

glutDisplayFunc(render);
glutKeyboardFunc(keyboard);
glutMouseFunc(mouse);

glutMainLoop();
}

void keyboard(unsigned char c, int x, int y)
{
if(c == 27){
    exit(0);
    }
}

void mouse(int button, int state, int x, int y)
{
if(button == GLUT_RIGHT_BUTTON )
{
    exit(0);
}
}

void render(void)
{   
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

glBegin(GL_TRIANGLES);
    glColor3f(1, 0, 0);
    glVertex2f(-0.5, -0.5);
    glColor3f(0, 1, 0);
    glVertex2f(0.5, -0.5);  
    glColor3f(0, 0, 1);
    glVertex2f(0.0, 0.5);
glEnd();

glutSwapBuffers();
}

Answer 1

some simple things that can cause problems in my experience (so make sure they are set!:) :

• check to see if C:\\MinGW\\bin is in your path variable if not, add C:\\MinGW\\bin to your PATH (type %path% in a console window to ensure the path property is applied to the window console session you are using)
• put glut32.dll into C:\\windows\\system32 so it can be located at runtime, or place it in the same directory as the executable you wish to run
• Just checked and my minGW has glut32.dll in c:\\mingw\\bin
• and libglut32.a in c:\\mingw\\lib
• and glut.h should be in c:\\mingw\\include\\GL

Apologies for the previous omission.

That should see you alright provided there are no other issues at play.

Let me know if you need more info/help :)

Addendum:

I located this link which whilst old may be of use to you in making the files available to mingw's environment.
