Starting with OpenGL in Ubuntu Linux [by Chandan]

Its just a few steps to work with the OpenGL in Ubuntu.
1. Install the required packages sudo apt-get install build-essential # standard C/C++ library & header files sudo apt-get install glutg3-dev # GLUT headers
2. Additionally, an Integrated Development Environment (aka, IDE) would be a good choice for easier programming. That's why, I've chosen Geany sudo apt-get install geany

Hope his helped you ;-)

Hiii...

When a run an openGL program in ubuntu it gives me the following error message.

Xlib: extension "GLX" missing on display ":0.0".

freeglut (./ex1): OpenGL GLX extension not supported by display ':0.0'

I am really struggling with this for quite sometime. Can you please help me what should be done to make openGL programs run in ubuntu? Your help is really appreciated. (I am using ubuntu 64 bit version).

is it using cpu or gpu, when i run it on fullscreen its really laggy and the cpu usage is 100%

[cdnatutube]

@pfbjjz No GPU... It is using just the on-board nVidia Chipset :)

@cdnatutube

Thanks. I guess there is a problem with Ubuntu11.10 - 64bit version. I have installed a fresh copy of Ubuntu 10.04 and everything is working fine.

@CubeVon I hope you know some basics of OpenGL. It has three basic libraries - glut (library "GLUT" on Windows), GL (library "OpenGL" on Windows) and GLU (library "GL Utilities" on Windows).

Since these libraries are not included in the standard C/C++ set, we have to specify their location for the compiler. For that, you can use -l (el) option along with the required library. By doing so, you are actually telling the compiler where to find it. -lm is for math library (for power, sqrt, etc).
