============
|
|
|
|
This is a short description of the things I had to do to get
|
|
FlightGear up and running under Linux.
|
|
|
|
1. Prerequisites:
|
|
|
|
Linux (of any Flavour), a 3DFX-card (Voodoo1 in my case). 3D
|
|
operations 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:
|
|
|
|
http://www.3dfx.com/software/download_glidel.html
|
|
|
|
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 2.6 (or greater) installed. I used 3.0 to
|
|
be on the safer side...
|
|
|
|
Grab it at"
|
|
|
|
ftp://iris.ssec.wisc.edu/pub/Mesa
|
|
|
|
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.
|
|
|
|
Grab it at:
|
|
|
|
http://reality.sgi.com/opengl/glut3/glut3.html
|
|
|
|
Note: glut-3.7 is included with Mesa 3.0 so if you've already
|
|
grabbed the latest version of mesa, you should have everything you
|
|
need.
|
|
|
|
2. Build FlightGear:
|
|
|
|
You will need the following files:
|
|
|
|
FlightGear-x.xx.tar.gz (source code)
|
|
base-x.xx.tar.gz (data files)
|
|
|
|
Unpack FlightGear-x.xx.tar.gz using :
|
|
|
|
tar xvfz FlightGear-x.xx.tar.gz
|
|
|
|
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
|
|
|
|
make
|
|
|
|
and wait for the make process to finish. Now become root (for 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. The solution is
|
|
either to play as root or make the /usr/local/bin/fgfs binary "setuid
|
|
root", i.e. when this binary is run root priviledges are given. Do
|
|
this by issuing (as root)
|
|
|
|
chmod +s /usr/local/bin/fgfs
|
|
|
|
A solution for this problem is upcoming, keep an eye on the 3Dfx
|
|
website.
|
|
|
|
3. Install the data files
|
|
|
|
Change to /usr/local/lib/FlightGear and unpack the data files:
|
|
|
|
tar xvfz WHERE_YOU DOWNLOADED_THE_FILES/base-x.xx.tar.gz
|
|
tar xvfz WHERE_YOU DOWNLOADED_THE_FILES/textures-x.xx.tar.gz
|
|
|
|
That's it...
|
|
|
|
4. Fly!
|
|
|
|
If everything went ok, simply type
|
|
|
|
runfgfs
|
|
|
|
at the prompt. You should see the FlightGear splash-screen and a few
|
|
seconds later you'll find youself somewhere in the desert, ready for
|
|
take-off.
|
|
|
|
5. Strange things happen...
|
|
|
|
A note on the behaviour of Voodoo boards:
|
|
|
|
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.
|
|
|
|
Enjoy!
|
|
|
|
6. Conclusion
|
|
|
|
I hope this document provides some help. If it does, send virtual/real
|
|
beer to me, if not flame me!
