Counter-Strike 2: LD_PRELOAD Fails to Load 'libstdc++.so.6'

[HarshRelapse]

CS2 crashes when I attempt to start it. When running CS2 via the command line with the following command:

steam steam://rungameid/730

an error message appears:

ERROR: ld.so: object '/usr/lib32/libstdc++.so.6' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

Additionally, my environment variables (printenv) show the same error:

ERROR: ld.so: object '/usr/lib32/libstdc++.so.6' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

I tried unlinking and re-exporting with the command export LD_PRELOAD+="${LD_PRELOAD+:}/usr/lib32/libstdc++.so.6" (from the Steam package's steam-wrapper.sh [steam/pkg/steam-wrapper.sh]), but the issue persists.

If you need any assistance or logs, I’m here to help! :)

Update: The Steam update from version 19 to 20 modifies the steam-wrapper.sh, which could resolve the issue. However, the latest version (20) is not yet available in the default unstable repository, so wait for the next sync!

We aim to sync once a week but it's not rigid depending on the week and what's there to sync (ie it could be sooner or later).

The latest patch is intended to fix this issue, yes. I'm a bit worried about it at the moment because in my initial work with the steam wrapper adding the 64bit libstdc++ to the preload caused the client to crash on startup. I'm not sure why the client is working now with it TBH. I'm hoping that more people on volatile will be able to test it before the sync, but I'm not sure how many people on volatile actually use steam besides myself.

So you can either wait for that sync, or use LD_PRELOAD="/usr/lib/libstdc++.so.6" %command% as your launch options for the game to get it working immediately.

I've switched to volatile and received the steam update. When I run the game via the command line (steam steam://rungameid/730) I still encounter the error: ERROR: ld.so: object '/usr/lib32/libstdc++.so.6' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.. However now CS2 works without any issues and a local bot test also performed well with good FPS. So there still seems to be a issue with libstdc++, but at least cs2 works flawlessly (in my short test) :)

[ReillyBrogan]

There's not actually an issue with it. That message is just saying that the 64bit steam/game binaries can't load the 32bit version of libstdc++ which is expected behavior. If you were running a 32bit game instead you'd see the same error about the 64bit version. Unfortunately there's no way to configure LD_PRELOAD separately for 32bit and 64bit, you just put both in and whichever one is valid for a given binary will be used.

I am gonna keep it open till the next sync :)
