What should i install for C++/opengl programming

[wannaBeHacker]

Hey can someone please tell me what packages i need to install to be able to program in c++ and in opengl.

i used to use eclipse.

And i want to do this all through the terminal, so please help me to do this through the terminal thank you!

For C++ programming you should install:
build-essential
manpages-dev (man pages about C++)

[hod139]

For OpenGL you want libgl1-mesa-dev and you probably also want libglu1-mesa-dev (for the glu* commands).

[wannaBeHacker]

thanks, but im really a super noob

how do i install the packages again?

sudo apt-get build-essential?

[dlai]

sudo apt-get install <package-name>

You can also use synaptic, which is the graphical interface for installing packages... It is in System->Administration->Synaptic Package Manager, if you are using Ubuntu. If you are using Kubuntu use Adept, I think it is in System Services (or something like that),

If you need any other help just say so... I've been doing quite a lot of SDL/OpenGL programming in ubuntu.

You will probably want to install SDL, it's a library that offers things like initializing the window, catching events (mouse/keyboard/window close) and some other stuff. It will be under libsdl in synaptic, I think you need "libsdl1.2debian" and "libsdl1.2-dev" you may also want "libsdl-image1.2-dev" which is a library that makes loading textures a LOT easier.

Another option, as opposed to SDL, is GLUT. It's a little more restrictive than SDL, but it's smaller and most people find it easier to use. I believe the packages are "freeglut3" and "freeglut3-dev"

These are things you'll need to install AFTER mesa because OpenGL doesn't initialize itself, you need a library like one of these to do it. Both of these are cross platform too.

Best of luck!

Hi, I'm trying to get OpenGL programming going, using Eclipse and glut. However, it doesn't work, I am using aaindex from the red book (http://opengl.org/resources/code/samples/redbook/) as a test, I include:


#include <stdlib.h>
#include <stdio.h>
#include <GL/glew.h>
#include <GL/glut.h>

but get errors like:


../main.cpp:140: undefined reference to `glutPostRedisplay'
../main.cpp:122: undefined reference to `glLoadIdentity'
../main.cpp:125: undefined reference to `gluOrtho2D'

I get an error for each call to any gl, glu or glut function. I added the option -lglut for g++ (I let Eclipse handle compiling, linking etc., but I read somewhere the -lglut option was necessary)

Note that the -h files are all found, no warnings there.

What am I missing?

Linker not finding the glut library. If there is a way, check the exact command Eclipse CDT is using to compile your program, or compile on the command line with
$ gcc <program.c> -o <binary> -lglut
and see.

Right now I feel really stupid, I simply added "-lglut" in the wrong place...

Though now that that works, I get another error:


freeglut (/media/D/MyDocuments/Exjobb/GPUtest/Debug/GPUTest): ERROR: Internal error <Visual with necessary capabilities not found> in function fgOpenWindow
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 4 (X_DestroyWindow)
Resource id in failed request: 0x0
Serial number of failed request: 14
Current serial number in output stream: 17

:???:

I'll search for solutions, as well as trying a different example, but meanwhile if someone has a suggestion, shoot.

It could be due to your X server not supporting the glX extensions. Do you have the glx module loaded and are you using a display driver (and card) that supports OpenGL?

I have a nvidia Quadro FX 3450/4000 card with nvidias driver installed. I'm new to Ubuntu (and Linux), so I'm not sure how to know if a glx module is loaded or not. In the nvidia X server settings program there is a section called OpenGL/GLX information that says: "Direct Rendering: Yes", if that's what you mean.

Then you're all right.

What parameters are you passing to glutInitDisplayMode?

[Cesa]

Then you're all right.

What parameters are you passing to glutInitDisplayMode?

GLUT_SINGLE | GLUT_INDEX

The program fails at glutCreateWindow (might be obvious from the error I guess)

Ok, I tried changing GLUT_INDEX to GLUT_RGBA, and than the program runs, still not sure what the problem is though.

[Cesa]

Ok, anyway, all I wanted to do was to get OpenGL running, which it does now, I don't need that specific example to work. The difference between GLUT_INDEX and GLUT_RGBA is something I just have to read up on, and if I need index I will deal with that problem then.

Thanks for your help.
