Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

In an ever lasting struggle to install Plib, which has a dependancy 'OpenGL' which even though openGL programs on my system (tux racer + openGL screen saver) are working absolutly fine.
ive become lost in a mass of meaningless cr@p
and it seems no1 can help.
i decided to install Mesa, but while downloading, i was reading all the files about it. it seems to be a REPLACEMENT for openGL.
i have an NVIDIA GeFOrce4 with the latest drivers installed, shouldnt i have REAL openGL ????
can some1 point me in the right direction...
plib will not install cos it says that openGL is not installed on my system.
am i missing a library ?
should i have put a symbolic link somwhere ?
and, isnt OpenGL meant to come as PART of linux ???
im using redhat 9.
ive just done a fresh install. frechly installed the NVIDIA driver (which wored fine) updated the XF86Config file properly.
and still, OpenGL is not installed on your system (plib rpm install)
or, Cannot find a working GL (tar install)
should i install MESA anyway ???
will i get a drop in performance ???
and why the H3ll is it so hard, to get OpenGL working on a system as common as Redhat 9, with a graphics card as common as NVIDIA geforce 4 !!!!
and wherever i go for help, all they tell me is to edit the XF86COnfig (which i always say ive already done (CORRECTLY)
and, are you sure u have installed NVidia binary .run file correctly in runmode 3.. YES !!!!!!!
ive been trying to get this thing installed for 3 days now.
it took 3 minutes under windows.
(and im so damn anti MS, so me saying that means ALOT !)
thanx to ANY1 wo can give any help at all......
i will be FOREVER in ur debt.
I'll see what I can do, but I'm at work right now and my linux machine is currently at home & buggered...
Mesa is an older OpenGL implementation and CAN be used by the DRI (Hardware acceleration for X Window) system. However, it mostly does software acceleration unless you have a 3dfx card...
OpenGL in DRI uses a library called libGL.so. This library then loads the appropriate hardware accelerated library specific to your card.
I don't know much about the nVidia drivers, but I would guess that if you have them installed, libGL.so should be dynamically loading them, and libMesaGL.so (the Mesa GL libraries) isn't needed at all.
Check the links on all of your *GL.so files, some of them may be pointing to the wrong place.
Also, if you have an older executable (Quakeworld comes to mind) they are sometimes linked directly to the libMesaGL.so file rather that to libGL.so and will run terribly unless you have a 3dfx card or some kind of workaround... I can't recall precisely, but I think what I did was create a symlink between libMesaGL.so and libGL.so and finally got hardware accelrated Quakeworld on my Rage128 but I digress...
The bottom line is, if you have DRI installed and the OpenGL drivers for your card, you should not need Mesa... DRI installs any part of Mesa that it actually requires, and full blown Mesa is only really needed if you have an obsolete 3dfx card or you want to try to use software rendering.
If it seems, as you say, that OpenGL is working, it doesn't look like you have a problem. If OpenGL wasn't working or you were using software rendering, you'd know, your 3D performance would be terrible, but it looks like you're ok.
What do you need to install plib for?
Also, GLU, GLUT etc... are simply libraries that run on top of OpenGL, don't worry about them, they are just abstractions to make programmers' lives easier..
Basically mesa is used for software 3d acceleration which is no good when you got hardware acceleration with your card.Actually it is no good anyway you look at it.You can have it on your system anyway - if your card does hardware acceleration it will continue to do so.GLU Glut and so on are development libraries that are required for some programs to compile.From what it sounds like whatever you try to compile doesn't because there are development lib's missing on your system.
Good luck in finding them - that's the main reason I use gentoo.
Well, my advice would be to first check on your RedHat 9 CD, they will most likely be there in RPM format, and plib as well.
If they are there, try installing the RPMs from the CD rather than using source packages, RPMs are generally more reliable if you get one that's built for your distro. They'll tell you if they have any dependency issues (which you then download the upgrade packages to and voila, no more issues..).
download and install the ones for RedHat 9, they should work since they are built for your distro.
As for your compilation problems with plib, again, I would say to try and find an RPM install first.
With regards to DRI it stands for "Direct Rendering Interface" and it is the hardware 3D acceleration layer for XFree86 (X Window) version 4 and higher. I believe you need the "load dri" line if you want hardware accelerated X, it is most likely recommended to be removed because it could cause a lot of problems if you don't have it installed properly (sort of like safe mode or something)...
BTW, what "instruction manual" are you referring to?
If Tux Racer and the OpenGL screensaver are working fine, it would appear you don't have any problems with DRI or OpenGL, just worry about trying to get plib installed...
As for Gentoo linux, I have never used it, but from what I hear it is a sourcecode based distribution with automatic updates. i.e. there are no releases, you just type in some command line and the system connects to the internet and automatically updates itself to all the newest packages, checks dependencies, re-compiles for optimization etc... If you really like compiling everything, it may be the way to go, but as I said, I have never used it.
