Your system information

Please describe your issue in as much detail as possible:

After last update of Dota 2 it doesn't launch but exits with error:

FATAL: /home/maxx/.local/share/Steam/steamapps/common/dota 2 beta/game/bin/linuxsteamrt64/libengine2.so not loaded
        dlerror(): /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by /home/maxx/.local/share/Steam/steamapps/common/dota 2 beta/game/bin/linuxsteamrt64/libengine2.so)

Full log

Please re-compile libengine2.so using older libstdc++ or link it statically using linker (g++ / ld) option -static-libstdc++.

Steps for reproducing this issue:

  1. Install Steam on CentOS/RHEL 7.6.
  2. Install Dota 2.
  3. Try to launch.

Hello @leonmaxx, please give https://github.com/ValveSoftware/Dota-2/issues/1532#issuecomment-446599112 a read.

Hello, thanks for fast reply!

On CentOS realpath is installed with coreutils package:

$ which realpath
/usr/bin/realpath

Next I removed pinned_libs_* and started steam, nothing changed. After this I tried to make symbolic links myself but found that there is no libstdc++.so* in steam-runtime sub-directory:

$ pwd
/home/maxx/.steam/steam/ubuntu12_32/steam-runtime

Does Proton version settings affects steam-runtime version? I have selected 3.16-6 Beta version now.

Kkisak-valve maintainer 2019-01-19 github

Steam client version decides what is in the steam runtime. Proton is not involved.

libstdc++.so.6 used by Dota 2 should be a symlink at <steam runtime dir>/amd64/usr/lib/x86_64-linux-gnu/libstdc++.so.6

Kkisak-valve maintainer 2019-01-19 github

What steam distro package are you using?

Lleonmaxx 2019-01-19 github

Never mind.
Packagers of steam RPM package, patched /usr/bin/steam script to remove libstdc++.so* libraries in steam-runtime to workaround some old bug.

I reverted that patch, copied libstc++.so* files from steam-runtime.tar.xz archive to steam-runtime/amd64/usr/lib/x86_64-linux-gnu directory, and started steam. Now there is proper links to libstdc++ from steam-runtime in pinned_libs_64 directory and Dota 2 works.

Thanks for Your help!

Kkisak-valve maintainer 2019-01-19 github

Glad to hear you got it working. Your issue should reported to your distro packager for Steam.

Closing as this isn't a Valve issue.
