Ok, I think that may have worked. At least as far as getting the header file in the compiler. Of course now I have a slew of link errors. I'm thinking these are probably just syntax errors, but could anyone look at these and tell me if their not a warning that I'm still possibly missing something else:

[Linker error] undefined reference to `glViewport@16'
[Linker error] undefined reference to `glMatrixMode@4'
[Linker error] undefined reference to `glLoadIdentity@0'
[Linker error] undefined reference to `gluPerspective@32'

[Linker error] undefined reference to `wglMakeCurrent@8'
[Linker error] undefined reference to `SwapBuffers@4'
ld returned 1 exit status

Ok. Usually when you get undefined references you're missing links to certain libraries.

Go into Dev-C++ and create a new project. When you're asked to choose the type of project click on the multimedia tab and then select the OpenGL image. Type in your project name, select your language and save the .dev file. Once you've done that you should be able to see the files that are in your project in a toolbar to the left. Open up the drop-down list by clicking on the '+' symbol and then remove the main.cpp file that's in there by default using the right-click menu. Now right click on the name of your project in the left toolbar and click on 'Add to Project'. Select the files you want adding and then go to Project->Project Options. Once you're in there click on the 'Parameters' tab. In the leftern most box you'll see a box titled 'Linker' that should have '-lopengl32' by default. Add in '-lglu32' and '-lglaux' into that box. You've now linked the glu32 and glaux library files, aswell as the opengl32 library which was in there by default. Try compiling your program again.

Ok this was as far as I got to in your instructions:

"Once you're in there click on the 'Parameters' tab. In the leftern most box you'll see a box titled 'Linker' that should have '-lopengl32' by default. Add in '-lglu32' and '-lglaux' into that box"

I opened the parameters tab but all I got was a pop-up with 2 boxes one that said "Enter parameters to pass to your program" and another that just said "Host Application". I didn't see anything about 'Linker'? But the previous instructions brought my errors down considerably. Now I'm just down to this:


[Linker error] undefined reference to `WinMain@16'

When included the gl-headers like this:
#include <gl\gl.h> // Header File For The OpenGL32 Library
#include <gl\glu.h> // Header File For The GLu32 Library
#include <gl\glaux.h> // Header File For The GLaux Library
Then they shall be in your IDE's include directory in the folder named "gl".

The macro: #include
When using the '<','>' the pre-compiler looks in the IDE's include dir.
When using the "," the pre-compiler looks in the additional include dir you specifyed in your IDE settings.

Have you solved it yet?

Well... "I don't mean to sound rude" either, but I really don't take you too seriously BorisTSR. First off I look at your user rating and made assumputions (probably like you did) and said to myself: 'This person is probably not a very advanced programmer either. They probably learned a couple things from hanging around forums and say stuff like this to new people to make themself feel like their better at programming then they really are.

As far as claiming I just copied and pasted something... I guess you didn't bother to read that I'm following a tutorial. That should tell you that YES! I'M USING SOMEBODY ELSE'S WORK! So I'm going to have to assume that you don't really read or understand what working from a tutorial means. The only difference between me and someone who does copy and paste is that I'm actually trying to learn the code. So if the syntax is off, blame NeHe or whoever wrote the tutorial.

Yes, your right I'm not the most advanced C++ programmer in the world. But as I've learned from my friend(who is a really advanced programmer) most of the time you start seeing similarities between the langauges and things becoming clearer. I've found this to be true while reading PHP 5 for Dummies. Even though PHP is a scripting language it has a lot in common with C++. Probably the clearest explanation of arrays and loops I've seen are in that book. So maybe you should check it out and see what I'm talking about. Then you might see I do have purpose trying to learn OpenGL.

And yes, I'm not the most familiar with the Dev-C++ IDE. But I have started to learn things I didn't know before from this thread. But I obviously can't learn anything from people like yourself. I'm sorry I asked questions that were supposedly "below" the beginer forum, this my first posting in these forums. But if I can just finish learning how to adjust the Dev Software to work the those tutorials by myself, I'll try to leave "real programmers" like yourself alone.

Guys come on he's learning, give him a break.

As a note, please use the [ source]code goes here[ /source] tags (without the spaces) next time so that your code is readable.

Your code works fine for me with opengl32, glu32 and glaux linked in.

Follow these steps:

Click on the 'Project' button in the toolbar and then go down to 'Project Options'


Click on the 'Parameters' tab


Add in the libraries by following this image


Good luck :-).
