[L4D2] Could not load library matchmaking

[jethrogb]

After installing L4D2, right after the intro video I get the error message "Could not load library matchmaking". When I click OK, the game exits.

[jethrogb]

This seems to be caused by primusrun. Perhaps it's not preserving LD_LIBRARY_PATH in the right way?

[jethrogb]

This shows up in the console:

 failed to dlopen /media/data/Games/LinuxSteam/SteamApps/common/Left 4 Dead 2 Beta/left4dead2/bin/matchmaking.so error=dlopen: cannot load any more object with static TLS

Some more info:

$readelf -l '/media/data/Games/LinuxSteam/SteamApps/common/Left 4 Dead 2 Beta/left4dead2/bin/matchmaking.so'|grep TLS
  TLS            0x0ee000 0x000ee000 0x000ee000 0x00000 0x00018 R   0x4

It seems to work when I run the game like this:

LD_PRELOAD=left4dead2/bin/matchmaking.so primusrun ./hl2.sh -game left4dead2 -steam

[jethrogb]

Spoke too soon. The game loads that way, but I can't start a game.

[linnik]

I think this is duplicate of #427

[jethrogb]

Perhaps, mine doesn't actually segfault.

[jethrogb]

It's a duplicate of https://github.com/ValveSoftware/steam-for-linux/issues/2383 though. Not sure why that's in steam-for-linux instead of source-1-games.

[linnik]

Do you use 32-bit architecture? I've seen some users which complain about dlopen issue only on this platform and never on x64.

[jethrogb]

$uname -a
Linux jethro 3.5.0-28-generic #48-Ubuntu SMP Tue Apr 23 23:03:38 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
$cat /etc/issue
Ubuntu 12.10 \n \l

You're right though that on 64-bit it's impossible to create shared libraries with position-dependent code. But HL2 is a 32-bit program.

[linnik]

Can you try to launch game with this method?

cd ~/.local/share/Steam/SteamApps/common/Left\ 4\ Dead\ 2\ Beta/
vblank_mode=0 primusrun ./hl2_linux -game left4dead2_beta -steam

[Heis]

Your method works flawlessly for me, linnik.

[tr37ion]

@linnik That's only working if I have started Steam before and start L4D2 form the commandline afterwards.

Any Idea how to modify the hl2.sh script that it works by using Steam?

[anonymous09]

I have same issue. $ uname -a Linux localhost 3.8.10-gentoo #1 SMP Sat Apr 27 07:22:16 EEST 2013 x86_64 AMD Phenom(tm) II X4 965 Processor AuthenticAMD GNU/Linux CPU: AMD Phenom(tm) II X4 965 GPU: AMD HD 7770 OS: Gentoo GNU/Linux amd64 Driver: Catalyst 13.4

BTW, this is works for me cd /media/data/Steam/SteamApps/common/Left\ 4\ Dead\ 2\ Beta/ ./hl2_linux -game left4dead2_beta -steam

[daugustin]

Can also confirm: Not working with Launch Options "optirun %command%" (other games work like that, like tf2) Working with cd Steam/SteamApps/common/Left\ 4\ Dead\ 2\ Beta vblank_mode=0 optirun ./hl2_linux -game left4dead2_beta -steam

[linnik]

If any of you would like to launch game manually every time, before Valve release a fix, i advise you to use export __GL_THREADED_OPTIMIZATIONS=1 from hl2.sh script - thats enables nVidia threaded optimizations.

I have the same issue.

using primusrun

manual starting the game works

[pete-h]

I found here: http://steamcommunity.com/app/223530/discussions/0/810923580581417316#p3 that you have to set the launch options to start L4D2B directly from steam to: LD_PRELOAD=./left4dead2/bin/matchmaking.so vblank_mode=0 PRIMUS_SYNC=1 STEAM_RUNTIME=1 primusrun %command%

The steam overlay doesn't work, but playing does :)

[filmor]

If you want the overlay to work use

 LD_PRELOAD=$LD_PRELOAD:left4dead2/bin/matchmaking.so primusrun %command%

You need this since the overlay also uses the preload mechanism.

[filmor]

This bug does still exist in the "promoted" L4D2 (Beta) on Linux.

[ghost]

Confirm that, same issue in the non-beta release. Bumblebee on linux.

[dsnettleton]

This bug affects me as well. Trouble launching on my nvidia card with bumblebee/primus, and intermittent segfaults while the game is running.

[tnbp]

dsnettleton, have you tried disabling workshop content? My games seem to crash less often after disabling "Informal Skyboxes."

[freehck]

I have the same issue while using primusrun. If I try to start L4D2 without primus, it works fine (but certainly with low performance).

I'm using: Distro: Debian GNU/Linux Jessie (testing, 8.0) WM: i3-wm (v4.5.1-2) Card: Nvidia GeFroce GTX 610M Additional info: I'm still using kernel 3.2.

I've prepared an strace log for this bug. You can download it from here: ftp://freehck.ru/l4d2-450-strace.log (21MiB)

[freehck]

Append a bit.

I've written a simple script test-450.sh [1] to check environment variables inside primusrun in order to check if LD_LIBRARY_PATH is correct while primusrun executes game. And more, I append LD_DEBUG flag in order to determine why there is a problem with matchmaking.so.

I've ran it with following command: % bash -c './test-450.sh' &> test-450.log

I append log file [2] for you.

Apparently a fix might be coming with one of the next updates: https://github.com/amonakov/primus/issues/103

[elthommy]

This bug affects me also

[pete-h]

Seems to be fixed for me with the latest L4D2 update :)

[ghost]

Fixed in latest update indeed

[freehck]

Fixed in the latest L4D2 update.
