status of linux games support

[arundel]

hi there.

does anybody know of a way to get linux games to work? i'm running HEAD (freebsd 8). so the linuxulator code should be the cutting edge. but still all linux games crash with the freebsd NVIDIA drivers.

the only way to run linux games is to install graphics/linux_dri. the port also installs a linux version of (glx)gears. if i anstall the NVIDIA drivers afterwards thus overwriting e.g. the libGL version installed by the linux_dri port (glx)gears segfaults.

what's the actual problem? is the linuxulator still missing some linux syscalls or are some syscalls buggy? it can't be the linux libraries, because they are exactly the same as the one's that ship with the linux NVIDIA drivers.

cheers.

p.s.: oh...and here's yet another issue. the linux drivers get installed into usr/lib. however all of the id software games have a hardcoded path to libGL.so.1 encoded which points to usr/local/lib. right now the NVIDIA Makefile checks a few locations (including usr/local/lib) for files like libGL.so.1 and deletes/unlinks them. probably because it's better to be sure the files only exist in one location and all the libs are the actual NVIDIA version. it would be nice however if the installer could create symlinks from usr/lib to /usr/local/lib. that way the id software games have a chance to find the NVIDIA libraries.

Which driver release are you using (please generate and attach an nvidia-bug-report.log file)? The NVIDIA FreeBSD graphics driver's Linux ABI compatibility support as such should work, at least there're no fundamental problems with it that I'm aware of. That said, there've been reports of problems (application crashes, specifically) with FreeBSD 8.0-CURRENT. The Linux libraries (libGL.so, etc.) should be installed to /compat/linux/usr/lib, not /usr/lib.

I'm also getting problems with Linux games. I've tested Linux acroread8, and this works, but Linux binaries which attempt to bind libGL crash and burn.

oh sorry. i guess i forgot to say that when i wrote /usr/lib i actually meant /compat/linux/usr/lib. my bad.

i installed 180.37 a few minutes ago. what happens when i try to run quake4 is that i get the following error message:

ERROR: SDL_GL_LoadLibrary libGL.so.1 failed: Failed loading libGL.so.1: /usr/local/lib/libGL.so.1: ELF file OS ABI invalid

so it seems quake4 looks for libGL.so.1 in /usr/local/lib. the linuxulator translates that path to /compat/linux/usr/local/lib. since there's no libGL.so.1 in that path the linuxulator then looks in the actual path (/usr/local/lib). there it finds the freebsd version of libGL.so.1. however since that's not the one quake4 needs it outputs the error message i've posted above.

now...what i've done to resolve that issue is to copy all the nvidia libraries from /compat/linux/usr/lib to compat/linux/usr/local/lib. that's why i proposed that the NVIDIA driver installation not only installs the linux libraries to /compat/linux/usr/lib, but also creates symlinks to /compat/linux/usr/local/lib, because almost all the id software games look for the libGL.so.1 in a hardcoded path (being /usr/local/lib which get's wrapped by the linuxulator to /compat/linux/usr/local/lib).

when i run quake4 again i get this error message:

--------------- R_InitOpenGL ----------------

signal caught: Segmentation fault

--------------- BSE Shutdown ----------------

i also tried running unreal tournament 2004 which doesn't look for libGL.so.1 in a hardcoded path. however the game also crashes with this error message (written to UT2004.log):

The libGL.so.1 load failure looks like a library load path setup problem, /usr/lib is the correct installation for the OpenGL libraries per the Linux OpenGL ABI and typically works fine. As to the segmentation fault, chances are you're experiencing the problem(s) with FreeBSD 8.0-CURRENT I referred to earlier. Unfortunately, I haven't had a chance to try reproducing this problem, yet.

so it seems quake4 looks for libGL.so.1 in /usr/local/lib. the linuxulator translates that path to /compat/linux/usr/local/lib. since there's no libGL.so.1 in that path the linuxulator then looks in the actual path (/usr/local/lib). there it finds the freebsd version of libGL.so.1. however since that's not the one quake4 needs it outputs the error message i've posted above.

Although it probably does not fix the segmentation fault, you can try the patching I added to the linux-ut port to remove the /usr/local/lib that is hard-coded into the binary. Look for the section concerning "Remove /usr/local from ut-bin lib search path" in the Makefile.

I still get a segmentation fault, but at least the program is dying on the correct library.

These same problems was fixed by a friend of mine and described in this pr more than an year ago
http://www.freebsd.org/cgi/query-pr.cgi?pr=118230
Unfortunately no one is taking care about that pr.
The fix worked for me too.
I also have linux-doom3, linux-enemyterritory (+ various mods), and rtcw.
None of the above required the manual fix.
And IMO they work better then in windows (way stable and faster) and linux (little faster+better audio)!

[rnejdl]

And on FreeBSD 7 I don't even have that directory

[tethys]:/usr/compat/linux/usr> ls
X11R6/ doc/ games/ kerberos/ libexec/ share/ tmp@
bin/ etc/ include/ lib/ sbin/ src/
[tethys]:/usr/compat/linux/usr>

All of this is in /usr/compat/linux/usr/lib as it should be with no symlinks needed:

[tethys]:/usr/compat/linux/usr/lib> ls | grep libGL
libGL.so.180.37
libGL.so.1@
libGLcore.so.180.37
libGLcore.so.1@
[tethys]:/usr/compat/linux/usr/lib>

I am running :

linux_base-fc-4_14

and

compat.linux.osrelease: 2.6.16

You should move to emulators/linux_base-f8

i followed the description in the PR, yet quake4 still crashes with the same error message.

[arundel]

here's a little script to set up a few symlinks in order for id software games to find the required libraries:

#!/bin/sh
cd /compat/linux/usr/local/lib/
ln -is ../../lib/libGL.so.1
ln -is ../../lib/libGLcore.so.1
ln -is ../../lib/libnvidia-tls.so.1

this however doesn't solve the issue which let's all linux 3d apps crash. maybe the freebsd-emulation mailinglist can help to identify the problem.

[arundel]

here's some more information concerning the problem. i think the reason the linux apps crash is due to the linux_futex syscall not being fully supported. i ran both ut2004 and quake4 using ktrace. these are the results.

there's a patch updating the linux futex code here: http://docs.freebsd.org/cgi/getmsg.c...ebsd-emulation

unfortunately it doesn't apply cleanly to CURRENT, but if you're running STABLE you might want to give it a try and see if linux 3d apps still crash after applying the patch.

cheers.
