Now whats this? I've tried removing dev-cpp n reinstalling it like over 5 times now. Still no help. The same bit of code works with the same dev-cpp version and the same glut lib's at home. But why not at work?

I'm writing a program that draws a checkerboard, then uses the mouse callback to place checkers on the checkerboard at the location of the mouse click.
I'm having a couple of problems with this. The most major problem is that when I rendered the checkerboard, the individual "squares" that make up the checkerboard are not squares. I give GL_POLYGON 4 vertices, and it gives me something that has five sides. and these are repeated 64 times to create a checkerboard of five-sided shapes. I've spent numerous hours trying to fix this, and I can't figure it out.Has anyone else had this sort of problem, and can you look at my code and see if there's something I'm missing that makes it do this? (the checkerboard is drawn in the display() method):
include <GL/glut.h>
include <stdlib.h>
include <windows.h>
include <math.h>
double wheight = 800.0, wwidth = 800.0;
double x, y, radius;
double red, green, blue;
int i, j;
int clicks = 0;
int k = 0;
int checkers[8][8]; / holds the place of checkers and colors of checkers on the board /
void myinit(void)
{
glClearColor(0.8, 0.8, 0.9, 1.0); / pale blue background /
/* set up viewing */
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluOrtho2D(-wwidth/2.0, wwidth/2.0, -wheight/2.0, wheight/2.0);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
/* init circle parameters */
radius = 32.0;
my second problem is that when the checkers are drawn, the colors are supposed to alternate with each click. I can get it to do this eight times, and then every time after that, they remain the same color each time I click on the "board". Can anyone help me with this?
Thanks a lot.

Hi,
I'm using dev-c++ 4.9.9.2 on windows xp, and I'm just tring to get to grips with it, etc, get something working, but every time I compile it it tells me glutInit undeclared (first use of this function)...
I followed the instructions in the getting started with open gl post, except i didnt put the library files into the lib folder as I dont think i had any...
This is the package i downloaded:
glut.3.7.6+.DevPak
any help would be greatly appreciated,

I guess you did not read the post directly above yours before you posted.
If you followed the directions in this thread, you did NOT get glut through the DevPack - this thread points you to a different site. That is the approach that has always worked for me.
And you don't generally "download" a DevPack - you use the WebInstaller which gets the pack and installs it automagically.
Please start a new thread with your question, and please, include your Basic 3. Always.
In particular, the coompile log portion of the Basic 3 tells us what libraries you linked, and exactly what the nature of your errors are...

There is much more to do than that. A header is just a list of functions, it doesn't do anything.
Please follow the directions given at the beginning of the thread. Get Glut where they tell you to, and put them where you are asked.
After you have done that, and if you still have issues, please tell us, step by step, what you did - where you got things, where you put them. Please do NOT simply type something like "I followed the directions"
Thanks.

Where did you get Glut from, and where did you put things?
Also, why are you using an option to link Objective C code? That makes no sense in the current context.
Wayne
I tell you what. Lets start at the beginning, so I get things straight about you and your setup.
Start a new thread please.
Give me the basic 3 pieces of information about your setup, plus, step by step, what you did to get and install Glut.
Wayne
p.s. The basic 3, in case you need to know, are talked about in the thread in the forum FAQ on question asking.
When the going gets tough, and you are tempted to get frustrated and mad, thats when you slow down and get more methodical. OK?

Hi - I read the thread now very carefully and the only thing I recognized, that I have done differently is, that I didn't put -lglu32 to the linker command line - and now the programm I posted works. I'm sorry for asking bothering questions - I still don't understand what these words in The Linker Command Line do but for that I probaby have to find a german forum.
The lines in question "link" the Glut code to yours - enabling it to work.

I believe I am telling about well known but not solved problem:
when compiling there are comes errors:
[Linker error] undefined reference to `__glutInitWithExit@12' and etc.
(1)My version of Dev-Cpp is 4.9.9.2
(2)The code is:
include <windows.h>
include <gl/glut.h>
include <stdlib.h>
void display(void)
{
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1.0, 1.0,1.0);
glBegin(GL_POLYGON);
glVertex3f(0.25, 0.25, 0.0);
glVertex3f(0.75, 0.25, 0.0);
glVertex3f(0.75, 0.75, 0.0);
glVertex3f(0.25, 0.75, 0.0);
glEnd();
glFlush();
}
void init(void)
{
glClearColor(0.0, 0.0, 0.0, 0.0);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
}
int main(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(250, 250);
glutInitWindowPosition(100, 100);
glutCreateWindow("hello");
init();
glutDisplayFunc(display);
glutMainLoop();
return 0;
}
(3) Full log is:
