Info on using Mesa 3.0 with Linux Quake I and Quake II
|
|

Disclaimer
|
|
----------
|
|
|
|
I am _not_ a Quake expert by any means. I pretty much only run it to
|
|
test Mesa. There have been a lot of questions about Linux Quake and
|
|
Mesa so I'm trying to provide some useful info here. If this file
|
|
doesn't help you then you should look elsewhere for help. The Mesa
|
|
mailing list or the news://news.3dfx.com/3dfx.linux.glide newsgroup
|
|
might be good.
|
|
|
|
Again, all the information I have is in this file. Please don't email
|
|
me with questions.
|
|

Linux Quake
|
|
-----------
|
|
|
|
You can get Linux Quake from http://www.idsoftware.com/
|
|
|
|
Quake I and II for Linux were tested with, and include, Mesa 2.6. You
|
|
shouldn't have too many problems if you simply follow the instructions
|
|
in the Quake distribution.
|
|
|
|

|
RedHat 5.0 Linux problems
|
|
-------------------------
|
|
|
|
RedHat Linux 5.x uses the GNU C library ("glibc" or "libc6") whereas
|
|
previous RedHat and other Linux distributions use "libc5" for its
|
|
runtime C library.
|
|
|
|
Linux Quake I and II were compiled for libc5. If you compile Mesa
|
|
on a RedHat 5.x system the resulting libMesaGL.so file will not work
|
|
with Linux Quake because of the different C runtime libraries.
|
|
The symptom of this is a segmentation fault soon after starting Quake.
|
|
|
|
If you want to use a newer version of Mesa (like 3.x) with Quake on
|
|
RedHat 5.x then read on.
|
|
|
|
The solution to the C library problem is to force Mesa to use libc5.
|
|
libc5 is in /usr/i486-linux-libc5/lib on RedHat 5.x systems.
|
|
|
|
Emil Briggs (briggs@tick.physics.ncsu.edu) nicely gave me the following
|
|
info:

I've already patched the mklib.glide file. You'll have to start Quake
|
|
with the script shown above though.

Here's my thoughts on the problem. On a RH 5.x system, you can NOT build
|
|
a libc5 executable or library. Red Hat just doesn't include the right
|
|
stuff to do it.
|
|
|
|
Since Quake is a libc5 based application, you are in trouble. You need
|
|
libc5 libraries.
|
|
|
|
What can you do about it? Well there's a package called gcc5 that does
|
|
MOST of the right stuff to compile with libc5. (It brings back older
|
|
header files, makes appropriate symbolic links for libraries, and sets
|
|
up the compiler to use the correct directories) You can find gcc5 here:
|
|
ftp://ecg.mit.edu/pub/linux/gcc5-1.0-1.i386.rpm
|
|
|
|
No, this isn't quite enough. There are still a few tricks to getting
|
|
Mesa to compile as a libc5 application. First you have to make sure that
|
|
every compile uses gcc5 instead of gcc. Second, in some cases the link
|
|
line actually lists -L/usr/lib which breaks gcc5 (because it forces you
|
|
to use the glibc version of things)
|
|
|
|
If you get all the stuff correctly compiled with gcc5 it should work.
|
|
I've run Mesa 3.0B6 and its demos in a window with my Rush on a Red Hat
|
|
5.1 system. It is a big hassle, but it can be done. I've only made Quake
|
|
segfault, but I think that's from my libRush using the wrong libc.
|
|
|
|
Yes, mixing libc5 and glibc is a major pain. I've been working to get
|
|
all my libraries compiling correctly with this setup. Someone should
|
|
make an RPM out of it and feed changes back to Brian once they get it
|
|
all working. If no one else has done so by the time I get the rest of my
|
|
stuff straightened out, I'll try to do it myself.

I'm using the Mesa-3.0beta7 and the RedHat 5.1 and QuakeII is
|
|
working fine for me. I had only to make a small change to the
|
|
Mesa-3.0/mklib.glide file, from:
|
|
|
|
|
|
GLIDELIBS="-L/usr/local/glide/lib -lglide2x
|
|
-L/usr/i486-linux-libc5/lib -lm"
|
|
|
|
to:
|
|
|
|
GLIDELIBS="-L/usr/i486-linux-libc5/lib -lglide2x"
|
|
|
|
and to make two symbolic links:
|
|
|
|
[david@localhost Mesa]$ ln -s libMesaGL.so libMesaGL.so.2
|
|
[david@localhost Mesa]$ ln -s libMesaGLU.so libMesaGLU.so.2
|
|
|
|
I'm using the Daryll's Linux glide rpm for the Voodoo2 and glibc (it
|
|
includes also the Glide for the libc5). I'm not using the /dev/3Dfx and
|
|
running QuakeII as root with the following env. var:
|
|
|
|
export
|
|
LD_LIBRARY_PATH=/dsk1/home/david/src/gl/Mesa/lib:/usr/i486-linux-libc5/lib
|
|
|
|
I think that all problems are related to the glibc, Quake will never
|
|
work if you get the following output:
|
|
|
|
[david@localhost Mesa]$ ldd lib/libMesaGL.so
|
|
libglide2x.so => /usr/lib/libglide2x.so (0x400f8000)
|
|
libm.so.6 => /lib/libm.so.6 (0x40244000)

|
|
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00000000)
|
|
|
|
You must get the following outputs:
|
|
|
|
[david@localhost Mesa]# ldd lib/libMesaGL.so
|
|
libglide2x.so => /usr/i486-linux-libc5/lib/libglide2x.so

|
|

|
|

Try using:
|
|
|
|
export LD_LIBRARY_PATH=/usr/i486-linux-libc5/lib
|
|
./quake2 +set vid_ref gl
|
|
|
|
to start the game... Works for me, but assumes that you have the
|
|
compatability libc5 RPMs installed.
