1. Introduction

This miniHOWTO is about how to get the OpenGL/GLX Linux QuakeWorld client
compiled and working on systems with standard OpenGL hardware acceleration
support.

This procedure was developed while struggling to get glqwcl.glx to work on a
system with Linux Slackware 7.0 (2.2.16), XFree86 4.0.1, a GeForce 256 DDR
video card, and NVIDIA's 0.9-4 MesaGL drop-in replacement lib/driver
(libGL.so.1.0.4).

2. QuakeWorld clients

If you'd like a ready to compile distribution of QuakeWorld that has this
HOWTO's procedures performed on it already, then you can download it at:

[http://www.comptechnews.com/~reaster/index.html#games] http://
www.comptechnews.com/~reaster/index.html#games

Otherwise ...

It seems that the glqwcl.glx binary available at least at [http://
www.quakeworld.net/] www.quakeworld.net in the package
qwcl-2.30-glibc-i386-unknown-linux2.0.tar.gz is not compiled properly since
on startup, it looks for libglide2x.so.

QuakeWorld clients come in several flavors:

OpenGL:
    glqwcl (3dfx only?)
   
    glqwcl.glx (MesaGL/XFree4)
   
Software only:
    qwcl (svgalib)
   
    qwcl.xl1 (x11/svgalib)
   

��*�This HOWTO is only concerned with getting the glqwcl.glx working with
    XFree86 4.x with GLX.
   
��*�This HOWTO assumes you have a working OpenGL libGL/libglx installation!
   

If you happen to have an Nvidia card and are interested in a complete HOWTO
for installing the Nvidia drivers and an assortment of OpenGL libraries (GLU,
glut, Qt, OpenGL man pages), then see the
NVIDIA-OpenGL-Configuration_miniHOWTO at:

[http://www.linuxdoc.org/HOWTO/mini/Nvidia-OpenGL-Configuration-mini-HOWTO/]
http://www.linuxdoc.org/HOWTO/mini/Nvidia-OpenGL-Configuration-mini-HOWTO/
-----------------------------------------------------------------------------

3. Download the Quake source

Download the Quake source code, q1source.zip, from [ftp://ftp.idsoftware.com/
idstuff/source/q1source.zip] ftp://ftp.idsoftware.com/idstuff/source/
q1source.zip. This zip file contains all versions of Quake1/QuakeWorld.

After compiling (read on first!), you will get version:
        LinuxGL (0.98) QuakeWorld 2.40 (as of this writing, Aug 19, 2000)    
                                                                             

Make a directory to hold the quake source:
        mkdir q1src                                                          
        cd q1src                                                             
        unzip ../q1source.zip                                                
        cd QW                                                                
        cp Makefile.Linux Makefile                                           
                                                                             
-----------------------------------------------------------------------------

4. Modify the Makefile

The Makefile can use cleaning up and the removal of all Mesa references since
the GLX version does not need it. Rather than provide a line by line account
of what I did to change the original Makefile, the modified Makefile that I
used, and a patch against the original Makefile.Linux to obtain my version of
the Makefile, are provided below.

This file can be copied and pasted as your Makefile to replace the original
Makefile/Makefile.Linux.

The following is a patch that you can apply to the original Makefile.Linux if
you feel like it. The command is simply:
        patch Makefile.Linux Makefile.Linux.patch                            
        cp Makefile.Linux Makefile

5. Fix the mouse grabbing

Fix the mouse hide problem.

The quake code, as it is, does not hide the mouse when you use it. The
pointer would remain visible and jitter around a fixed point in the middle of
the screen - very annoying. I found the following simple fix in a mail
archive about glx development at: [http://lists.openprojects.net/pipermail/
glx-dev/1999-October/000994.html] http://lists.openprojects.net/pipermail/
glx-dev/1999-October/000994.html

See the patch listing and the link to download it below, or you can make the
changes yourself.
        cd q1src/QW/client                                                   
        edit the file: gl_vidlinuxglx.c                                      
                                                                             

At the top of the function called install_grabs(void) (Line 234), add the
following code:
        static void install_grabs(void)

                blank = XCreateBitmapFromData (dpy, win, data, 1, 1);                  
                if(blank == None) fprintf(stderr, "error: out of memory.\n");          
                cursor = XCreatePixmapCursor(dpy, blank, blank, &dummy, &dummy, 0, 0); 
                XFreePixmap (dpy, blank);

The 8th parameter to XGrabPointer should be changed from "None" to "cursor"
to use the blank cursor:
        XGrabPointer(dpy, win,                                               
                         True,                                               
                         0,                                                  
                         GrabModeAsync, GrabModeAsync,                       
                         win,                                                
                         cursor,                                             
                         CurrentTime);                                       
                                                                             
(see: man XGrabPointer)

This fix might work for the other client builds if you make similar changes
in the appropriate *vid*.c file. As it is, this creates a memory leak as it
allocates another Cursor object everytime through and doesn't call
XFreeCursor() but this is probably not a problem since I don't think a 1x1
cursor is using much memory. If you want, you can apply the following patch
against q1src/QW/client/gl_vidlinuxglx.c (patch gl_vidlinuxglx.c patchfile).
Just cut and paste the contents between the begin/end patchfile lines into a
file called gl_vidlinuxglx.c.patch (or whatever you want to call it). Save
patchfile in the q1src/QW/client directory where gl_vidlinuxglx.c is. Then
run the command:
        patch gl_vidlinuxglx.c gl_vidlinuxglx.c.patch                        
                                                                             

This patch file will make gl_vidlinuxglx.c such that it doesn't have any
memory leak. You can download this patch file at: [http://

It is handy to bind some keys at the quake console to toggle mouse grabbing:
        bind q "_windowed_mouse 0"                                           
        bind w "_windowed_mouse 1"                                           
                                                                             
-----------------------------------------------------------------------------

6. Compile!

Compile (finally!)

Just run make with no parameters from where the Makefile is located:
        cd q1src/QW                                                          
        make                                                                 
                                                                             

If all goes well, you will have a binary, glqwcl.glx, in the
releasei386-glibc directory. Copy glqwcl.glx to another directory (like "qw")
and then from a Quake cd or other quake installation, copy the id1 directory
and any other game directories you like/have - ctf, Fortress etc - to your
new quakeworld directory.
-----------------------------------------------------------------------------

7. Running glqwcl.glx

Running the game.

You might want to run it like this from XQF: glqwcl.glx -width 1280 -height
1024 (or any other resolution your system can support)

XQF is a nice program to find QuakeWorld servers and can be found at: [http:/
/www.linuxgames.com/xqf] http://www.linuxgames.com/xqf

To run the game fullscreen requires starting the game at the same resolution
as your X desktop. If you are running a desktop environment, you might not be
able to hide everything. The sure way to get a fullscreen experience is to
run XFree86 on its own without any desktop environment or window manager
loaded:

XFree86 &
    This starts X without any desktop environment or window manager. /etc/X11
    /xinit/xinitrc normally starts your desktop.
   
CTRL-ALT-'-' and CTRL-ALT-'+'
    Switches to the resolution you want. Check your /etc/X11/XF86Config if
    you don't have any other resolutions available.
   
CTRL-ALT-F1
    Switches back to the text console.
   
xterm -display localhost:0.0 &
    All X applications accept a -display command line argument to tell it
    which X server to display on. Every X program is an X server client. 0.0
    represents the screen on F7, 1.0 on F8, etc. localhost is your computer.
    Its possible and very common to execute an X program on one computer but
    have it display on some other workstation. localhost could be an IP
    address or the dns name of any computer running X that is accepting
    connections from where you run the X client application program.
   
ALT-F7
    Switches back to X 0.0. Using xterm, start XQF or whatever program you
    use to launch Quake.
   
glqwcl.glx -width w -height h
    Tell your quake launcher to start it like this, where w and h are the
    resolution you are at. A good resolution is 1024 by 768.
   

Light effects.

At the console, you can try turning on and off the flashblend function and
see which lighting effects you prefer:
                gl_flashblend 0                                              
                gl_flashblend 1                                              
                                                                             

When it is on (1), you may notice colored light effects around flags and
special items. In this mode, you may NOT see flashes from weapons and light
on the walls from rockets. The exact effects of toggling flashblend may
depend on your specific OpenGL installation.

When it is off (0), there may not be any COLORED light, but otherwise all
light effects work. Flags and special items have a glow around them and light
up surrounding surfaces. Weapons flash when fired and rockets light up
everything around them as they travel.
