Clear Step by Step Process for using GLUT with Dev-CPP Required

OpenGL OpenGL: Basic Coding
1

I was trying to use GLUT with Dev-CPP. It seems it does not work bcos the linker is giving some undefined references error.

Please provide help.

Regards and thanks in advance.

2

it might help if you actually post the linker’s error messages

3

For example I used

glClearColor(1,0,0,1);

The linker gives undefined reference to

__imp__glClearColor…

!!! :confused: :eek:

4

I have used the line

#include <GL\glut.h>

and completed the neccessary formalities of copying the library files and dll files to the necessary places.

Do I need to locally compile again… ???

Here are the compiler message while compiling

You should link the libraries with Dev-Cpp, this IDE’s using MingW compiler (which is a winport of Gcc\un!x)

you should link libs like you linked glu library, for opengl lib and glut lib, because glut != opengl
-lgl -> opengl lib
-lglu32 -> glu lib // you linked that
-lglut -> glut lib
-lwhat_you_want -> what you want lib

hope that helps

Ya I compiled with Dev-CPP only which works on MingW32.

Unfortunately that -lgl option is not working … !!!

That means I should have a file name libgl.a or something… Where can I get that file ???

Please help…

Help this the code and it is not working
#include <windows.h>
#include <GL\glut.h>

void init()
{
glClearColor(1,0,0,1);
glOrtho(0,1,0,1,0,1);
}

void display()
{
glClear(GL_COLOR_BUFFER_BIT);
glFlush();
}

int main(int argc, char **argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB|GLUT_SINGLE);
glutInitWindowSize(800,600);
glutInitWindowPosition(5,20);
glutCreateWindow(“Tutorial 1”);
init();
glutDisplayFunc(display);
glutMainLoop();
return 0;
}
