I search www.opengl.org but I can't find any package for OpenGL
installation. Why so strange?

Any way to install OpenGL on Ubuntu?

Thanks

 From root, or use sudo:

apt-get install freeglut3
apt-get install freeglut3-dev  # if you want to develop programs
apt-get install freeglut3-dbg  # maybe of some use

does it for me.

You may need to look at System/Administration/Hardware Drivers to 
install non-open-source drivers for your graphics card.

Hope this helps,

Jon C.

If you want hardware acceleration this depends on your graphics card.
However installing the libgl1-mesa-dev and libglu1-mesa-dev packages is
probably the first thing you'll want to do (and it gives you a software
implementation of OpenGL and the necessary headers for development).

Ubuntu is not a good development platform. I'd try Gentoo if I was you.
There, you get OpenGL as a part of X. Maybe that's the case with Ubuntu
also.

Sorry, I am a new guy trying to use OpenGL. But I am a little confused
about the OpenGL. I can't find the download package in its offical
site. So it is not a real package for each system but just a standard
for drawing graphics?

On my computer, I just need to install the OpenGL Utility, is it right?

Thanks

Well, If you use ubuntu you have some standard way of installing
packages. All you need for OpenGL development canbe found among those.
Just install packages like libgl1-mesa-dev, libglu1-mesa-dev or
freeglut3-dev (if you want glut, as needed for the examples from the
"OpenGL programming guide") the way you would install any other standard
ubuntu package (using synaptic or on the command line "apt-get install
freeglut3-dev" or whatever way you prefer to install such packages). Oh,
and you'll want to install the mesa-utils package as well, since it
contains glxinfo, which will be a useful tool to find out more about
your OpenGL (and if you come back to this newsgroup asking questions
about some OpenGL problem it's likely that people will want to see the
glxinfo output, sincs it can help diagnose problems).

OpenGL isn't open-source. There's no public open-source package to install. 
MESA is an open-source implementation of most of OpenGL. If you then install 
a proprietary driver (from nVidia or ATI), it will supply "opengl" in an 
optimized form for you. So, after installing the mesa packages for your 
ubuntu, if you have nVidia or ATI graphics cards, install their Linux 
drivers.

see:
http://packages.ubuntu.com/search?suite=default&section=all&arch=any&searchon=names&keywords=mesa

for various packages available.

Could you please elaborate this statement?

This advice is a bit too general. For older ATI cards (X850 and earlier)
you probably do not want to install the proprietary driver, since the
free one from Mesa is already better (and the non-free drivers already
dropped support for several older cards). If you have such an older card
(or a current Intel graphics card) you probably will want to install the
libgl1-mesa-dri package.

Because OpenGL is just the API _specification_. What you need is in fact an 
_implementation_. Now on a considerably recent Ubuntu installation an OpenGL 
implementation called "Mesa" is installed by default.

However what you're probably looking for is the stuff required to compile 
programs using OpenGL. Those are in the Mesa development packages.

It's probably there already, but you probably need the dev-packages:

apt-get install libgl1-mesa-dev

You might also want/need to install some other packages, like GLEW, 
FreeGLUT, SDL, etc.
