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. You'll have to start Quake -with the script shown above though. - - - -********************** - -Daryll Strauss writes: - -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. - - - |Daryll - - - -********************* - -David Bucciarelli (tech.hmw@plus.it) writes: - -I'm using the Mesa-3.0beta7 and the RedHat 5.1 and QuakeII is -working fine for me.
