Revision 1.2 | 2000-01-04 | Revised by: rbe

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

# 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).

The lastest version of this mini-HOWTO can be found at:

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:

# 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

Otherwise ...

It seems that the glqwcl.glx binary available at least at 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/

# 3. Download the Quake source

Download the Quake source code, q1source.zip, from 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.

Figure 1. Makefile, cleaned up for compiling the GLX version.

# 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

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)
    	{
    		/* vars to make blank cursor */
    		Pixmap blank;
    		XColor dummy;
    		char data[1] = {0};
    		Cursor cursor;

    		/* make a blank cursor */
    		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);
    		Con_Printf("Cursor blanked.\n");

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://www.comptechnews.com/~reaster/mini-HOWTO/LinuxGL-QuakeWorld-mini-HOWTO/gl_vidlinuxglx.c.patch.

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

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.

HAVE FUN!
