Building On Red Hat 7.3

Download the utah-glx-src-latest.tar.gz package
Untar it

cd glx-xf4

Download Mesa 3.2.1
(http://telia.dl.sourceforge.net/sourceforge/mesa3d/MesaLib-3.2.1.tar.gz)

Untar it

./configure  --without-mmx-asm --without-3dnow-asm --disable-mga \
	     --disable-mach64 --disable-i810 --disable-s3virge  \
	     --disable-s3savage --disable-sis6326

If you know you will only be running on newer processors you can enable MMX
and on the Athlon and K6 enable 3dnow. You need to disable the other cards
as they are not yet ported over. If you want to use this driver with a non
Nvidia card join the utah-glx-dev list and lend a hand.

make
cp servGL/libglx.so /usr/X11R6/lib/modules/extensions/
cp glx.conf /etc/X11/glx.conf

Since XFree86 will load .so before .a archives you can leave the old module
there without problems. If you swap card you will need to remove the
libglx.so

Edit /etc/X11/XF86Config-4

In the Device section for the Nvidia chipset add the line "VideoRAM 8192" to 
reserve memory for the 3D subsystem. In the modules section commend out the
load of GLcore and dri.


The final problem you will hit is that the GL libraries shipped with the
base Red Hat 7.3 issue requests that Mesa 3.2 without DRI does not handle.
3D programs will exit with the message

GLNoDriverPrivatesX Error of failed request:  GLXUnsupportedPrivateRequest
  Major opcode of failed request:  143 (GLX)
  Minor opcode of failed request:  17 (X_GLXVendorPrivateWithReply)
  Serial number of failed request:  20
  Current serial number in output stream:  20

Once Utah-glx is using Mesa-4 this problem ought to go away.

export LD_LIBRARY_PATH=wherever/glx-xf4/mesa/libGL

will ensure that commands you run find the "pure" Mesa 3.2.1 libgl and use
that to communicate with the server.
