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. + +If you have information to contribute to this file please send it to +me at brianp@elastic.avid.com + + + +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 only know what works on a RedHat 5.0 distribution. RH5 includes +> a full set of libraries for both libc5 and glibc. The loader ld.so +> uses the libc5 libraries in /usr/i486-linux-libc5/lib for programs +> linked against libc5 while it uses the glibc libraries in /lib and +> /usr/lib for programs linked against glibc. +> +> Anyway I changed line 41 of mklib.glide to +> GLIDELIBS="-L/usr/local/glide/lib -lglide2x -L/usr/i486-linux-libc5/lib" +> +> And I started quake2 up with a script like this +> #!/bin/csh +> setenv LD_LIBRARY_PATH /usr/i486-linux-libc5/lib +> setenv MESA_GLX_FX f +> ./quake2 +set vid_ref gl +> kbd_mode -a +> reset + + +I've already patched the mklib.glide file.
