2 Info on using Mesa 3.0 with Linux Quake I and Quake II
9 I am _not_ a Quake expert by any means. I pretty much only run it to
10 test Mesa. There have been a lot of questions about Linux Quake and
11 Mesa so I'm trying to provide some useful info here. If this file
12 doesn't help you then you should look elsewhere for help. The Mesa
13 mailing list or the news://news.3dfx.com/3dfx.linux.glide newsgroup
16 Again, all the information I have is in this file. Please don't email
19 If you have information to contribute to this file please send it to
20 me at brianp@elastic.avid.com
27 You can get Linux Quake from http://www.idsoftware.com/
29 Quake I and II for Linux were tested with, and include, Mesa 2.6. You
30 shouldn't have too many problems if you simply follow the instructions
31 in the Quake distribution.
35 RedHat 5.0 Linux problems
36 -------------------------
38 RedHat Linux 5.x uses the GNU C library ("glibc" or "libc6") whereas
39 previous RedHat and other Linux distributions use "libc5" for its
42 Linux Quake I and II were compiled for libc5. If you compile Mesa
43 on a RedHat 5.x system the resulting libMesaGL.so file will not work
44 with Linux Quake because of the different C runtime libraries.
45 The symptom of this is a segmentation fault soon after starting Quake.
47 If you want to use a newer version of Mesa (like 3.x) with Quake on
48 RedHat 5.x then read on.
50 The solution to the C library problem is to force Mesa to use libc5.
51 libc5 is in /usr/i486-linux-libc5/lib on RedHat 5.x systems.
53 Emil Briggs (briggs@tick.physics.ncsu.edu) nicely gave me the following

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

83 Here's my thoughts on the problem. On a RH 5.x system, you can NOT build
84 a libc5 executable or library. Red Hat just doesn't include the right
87 Since Quake is a libc5 based application, you are in trouble. You need
90 What can you do about it? Well there's a package called gcc5 that does
91 MOST of the right stuff to compile with libc5. (It brings back older
92 header files, makes appropriate symbolic links for libraries, and sets
93 up the compiler to use the correct directories) You can find gcc5 here:
94 ftp://ecg.mit.edu/pub/linux/gcc5-1.0-1.i386.rpm
96 No, this isn't quite enough. There are still a few tricks to getting
97 Mesa to compile as a libc5 application. First you have to make sure that
98 every compile uses gcc5 instead of gcc. Second, in some cases the link
99 line actually lists -L/usr/lib which breaks gcc5 (because it forces you
100 to use the glibc version of things)
102 If you get all the stuff correctly compiled with gcc5 it should work.
103 I've run Mesa 3.0B6 and its demos in a window with my Rush on a Red Hat
104 5.1 system. It is a big hassle, but it can be done. I've only made Quake
105 segfault, but I think that's from my libRush using the wrong libc.
107 Yes, mixing libc5 and glibc is a major pain. I've been working to get
108 all my libraries compiling correctly with this setup. Someone should
109 make an RPM out of it and feed changes back to Brian once they get it
110 all working. If no one else has done so by the time I get the rest of my
111 stuff straightened out, I'll try to do it myself.

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

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

190 to start the game... Works for me, but assumes that you have the
191 compatability libc5 RPMs installed.
