GLIBC update broke EAC for most games that use it

[Jelgnum]

Titles With Problems:
Most titles that use Easy AntiCheat and officially support Linux
tested ( Multiversus, Elden Ring, Apex Legends [mixed results])

Error Description:

Launch Error: Failed to load the anti-cheat module

To recreate:
Be running the newest GLIBC in this case 2.36
Have Steam (not flatpak vers.)
Hardware: happens on both nvidia and amd systems

1. Install one of games mentioned above
2. launch game
3. game will most likely error

Sorry if this isn't the correct place to report the error, but I figured this team helped create the EAC module, so you would be the ones to contact.

Yeah Confirming. Bloodhunt EAC breaks with glibc 2.36

Apex Legends is still fine. Apex using the older non-EOS EAC i guess?

[amoldybuffalo]

Just happened to me.

[bg2908]

Happen to me with Elden Ring

[nicodemus144]

can confirm, also for Video Horror Society.

[perru]

Confirmed on Multiversus.

Try it at workaround :
pacman -U https://archive.archlinux.org/packages/g/glibc/glibc-2.35-6-x86_64.pkg.tar.zst https://archive.archlinux.org/packages/l/lib32-glibc/lib32-glibc-2.35-6-x86_64.pkg.tar.zst

EDIT : Nop, don't try it, it broke my system wich need glibc 2.36...

[amoldybuffalo]

Little bit of a workaround: use steam flatpak until the issue gets fixed.

[Mast3rwaf1z]

also broken for me with elden ring

Edit: as expected, a workaround is to use the flatpak steam version, you can just add your steam library as a filesystem and skip having to install the games again

I was having problems with glibc 2.35 and rogue company
can confirm other EAC games broke with 2.36 now

[seafer6969]

Confirmed for GNU libc 2.36 on Arch Linux 5.18.15-arch1-2 on the following games:
Multiversus
Dragonball FighterZ

Yea same lmao, thankfully easily fixable by updating with pacman on a live usb inside chroot

Can Confirm, on Arch Linux. Played a few games in the morning (on Multiversus), ran a pacman update, came back to this issue

You can safely(ish) downgrade glibc with the "downgrade" utility on the AUR. Just make sure to include lib32 and gcc-libs. I forgot GCC-libs and had to downgrade from the command line.

sudo downgrade glibc lib32-glibc gcc-libs

Multiversus is able to start successfully after the downgrade.

Experienced the same issue. The steam flatpak works so I'll maybe switch to that indefinitely when i get gamemode working

Thank you! I was midtype of reverting it but you made it much much easier. Whenever I try downgrading though, it borks my system (I get faced with a stuck "/dev/sda: clean" bootup screen, reverting downgrade fixes this). Specifically, I think its the gcc-libs breaking dependency with gcc-libs=12.1.1-4. I'll mess around a bit more, but thanks!

Edit: After downgrading gcc as well, it has no error message about dependencies, but won't boot up multiversus nor steam, weirdly
