1. Prerequisites:
|
||||
|
||||
You need to understand the concepts of 3D acceleration under Linux and
|
||||
the needed libraries. An excellent source of information is the "Linux
|
||||
Quake-HOWTO" which can be found at
|
||||
- You need to understand the concepts of 3D acceleration under Linux
|
||||
and the needed libraries. You will need to install and configure
|
||||
accelerated drivers for your specific video card. It is beyond the
|
||||
scope of this document to describe the process for your specific
|
||||
video card.
|
||||
|
||||
http://www.linuxquake.com
|
||||
More and more distributions are coming out with pre-packaged drivers
|
||||
so look around (just in case) before you go out and build software
|
||||
yourself.
|
||||
|
||||
If anything seem to be wrong with your 3D setup, check there first!
|
||||
Here are some potentially useful sites, but be careful and find the
|
||||
specific instructions for your specific video card and distribution:
|
||||
|
||||
You need Linux of course (any flavour) and a 3DFX-card (Voodoo1 in my
|
||||
case). 3D rendering without hardware support can force even the
|
||||
fastest PII to its knees. To make use of the accelerator board you
|
||||
need"

|
||||
|

- the GLIDE library installed. Grab it at:
|
||||
Without accelerated 3d rendering, FlightGear could never run at
|
||||
decent frame rates, even on the fastest CPU's.

||||

|
||||
|
||||
and install. There is even an install script contained that will do
|
||||
things for you. The canonical place for GLIDE is /usr/local/glide,
|
||||
if you prefer another location, you'll have to edit the Makefile for
|
||||
FlightGear by hand. Be sure to read and understand the file
|
||||
/usr/local/glide/README.
|
||||
|
||||
- the MESA library version 3.0 (or greater) installed.
|
||||
|
||||
Grab it at:
|
||||
|
||||
http://www.mesa3d.org/
|
||||
|
||||
unpack it and run "make linux-glide" in the Mesa directory. Follow
|
||||
the instructions in the README file, take a close look at
|
||||
README.3DFX and play with the demo programs. Relax, rejoice :-)
|
||||
|
||||
- the GLUT library version 3.7 (or greater, aka GameGLUT) installed.
|
||||
- You will need the GLUT library version 3.7 (or greater, aka

Grab it at:

Note: glut-3.7 is included with Mesa 3.x so if you've already
|

grabbed the latest version of mesa, you should have everything you

need.
|
||||
|
||||
Alternatively, you can use the 3D-stuff that came along with your
|
||||
Linux distribution. At least RedHat (5.3 and later) and S.u.S.E. 6.0
|
||||
(or later) contain all the things you need.
|
||||
(or later) may contain all the things you need depending again on
|
||||
your video card.
|
||||
|
||||
- (optional) the 3DFX kernel module.
|
||||
- Steve Baker's plib library. Get it from:
|
||||
|
||||
Without this thingy installed, access to your accelerator board
|
||||
needs to be SUID root, which bad practice (and a _huge_ security
|
||||
hole). Get the 3DFX module from
|
||||
http://plib.sf.net
|
||||
|
||||
http://www.xs4all.nl/~carlo17/3dfx/index.html
|
||||
... and follow the instructions there to install it.
|
||||
|
||||
and install it:
|
||||
- SimGear. Get it from:
|
||||
|
||||
mkdir 3dfx
|
||||
cd 3dfx
|
||||
tar xvfz ../Dev3Dfx-2.7.tar.gz
|
||||
make
|
||||
cp 3dfx.o /lib/modules/`uname -r`/misc
|
||||
mknod /dev/3dfx c 107 0
|
||||
insmod 3dfx
|
||||
http://www.simgear.org
|
||||
|
||||
alternatively, you can get the RPM from there ind use rpm for
|
||||
installation.
|
||||
... and follow the instructions there to install it.
|
||||
|
||||
- Steve Baker's plib library.
|
||||
|
||||
get it from
|
||||
|
||||
http://www.woodsoup.org/projs/plib/
|
||||
|
||||
and follow the instructions in README.plib.
|
||||
|
||||
- (optional) the gpc libraries.
|
||||
|
||||
Read the README.gpc files to understand what they are good for
|
||||
and decide whether you need to download them. If you don't want to
|
||||
build your own sceneries, you might not need them.
|
||||
|
||||

and cd info FlightGear-x.xx. Run:

./configure

|

and wait a few minutes. configure knows about a lot of options. Have a
|
||||
look at the file INSTALL in the FlightGear source directory to learn
|
||||
about them. If run without options, configure assumes that you will
|

install the data files under /usr/local/lib/FlightGear. Assuming

configure finished successfully, simply run

|
||||
example by using the su command) and type
|
||||
|
||||
make install
|
||||
|
||||
This will install the binaries in /usr/local/bin. Notice that the name
|
||||
of the FlightGear binary is "fgfs".
|
||||
|
||||
Another problem with Linux/Glide is permission-related. All programs
|
||||
accessing the Accelerator board need root permissions (or the kernel
|
||||
module mentioned above installed). I _strongly_ recommend the latter.

This will install the binaries in /usr/local/bin. Notice that the

name of the FlightGear binary is "fgfs".

5. Strange things happen...
|
||||
|
||||
A note on the behaviour of Voodoo boards:
|
||||
We have mailing lists set up for specific FlightGear problems,
|
||||
bugs, and questions. Please see the flightgear web page for
|
||||
details.
|
||||
|
||||
Your card comes packaged with a loop-through-cable. If you have only
|
||||
one monitor, then the Voodoo will take it over when used. This means
|
||||
that all the applications on your desktop will continue running but
|
||||
you'll only see the FlightGear screen. If your window manager uses a
|
||||
focus-follows-mouse policy, don't move the mouse. If you lose the
|
||||
focus, there's no way to shut down FlightGear graciously! Better
|
||||
solution: Use two monitors, one for your desktop, connect the other
|
||||
one to your accelerator. You'll then get a window on your desktop
|
||||
which manages all keyboard events and you're still able to see your
|
||||
desktop.
|
||||
|
||||
A final note: There are several types of VooDoo cards out there, so be
|
||||
sure to get the correct version of Glide!
|
||||
|
||||
Enjoy!

I hope this document provides some help. If it does, send virtual/real
|

beer to me, if not flame me!
