![]() Runtime issues 'GLBCXX_3.X.XX' not found when using Bumblebee Gdb will open, then type run which will start steam and once crash happens you can type backtrace to see call stack. You can set DEBUGGER environment variable with one of gdb, cgdb, valgrind, callgrind, strace and then start steam.įor example with gdb $ DEBUGGER=gdb steam It is possible to debug Steam to gain more information which could be useful to find out why something does not work. This means you do not have to run Steam from the command-line to see that output. The Steam launcher redirects its stdout and stderr to /tmp/dumps/ USER_stdout.txt. See: steam-for-linux issue 7114 A similar effect can be achieved by starting steam with steam 2>&1 (Discuss in Talk:Steam/Troubleshooting) Reason: Steam no longer redirects stdout and stderr to /tmp/dumps/ USER_stdout.txt by default. $ for i in $(pgrep steam) do sed '/\.local/!d s/.* //g' /proc/$i/maps done | sort | uniq xargs ldd | grep 'not found' | sort | uniqĪlternatively, run Steam with steam-runtime and use the following command to see which non-system libraries Steam is using (not all of these are part of the Steam runtime): $ file * | grep ELF | cut -d: -f1 | LD_LIBRARY_PATH=. If individual games or Steam itself is failing to launch when using steam-native you are probably missing libraries. Please note that most of these "missing" libraries are actually already included with Steam, and do not need to be installed globally. game_executable is likely located somewhere in ~/.steam/root/steamapps/common/. ![]() You can find out what libraries it requests by running ldd game_executable. If a game fails to start, a possible reason is that it is missing required libraries. If you figure out a missing library you can use pacman or pkgfile to search for packages that contain the missing library. To correctly debug a program or shared library it is therefore important that these environment variables in your debug environment match the environment you wish to debug. The LD_LIBRARY_PATH and LD_PRELOAD environment variables can alter which shared libraries are loaded, see ld.so(8). To see the shared libraries required by a program or a shared library run the ldd command on it, see ldd(1). You can also use the Steam native runtime without steam-native-runtime by manually installing just the packages you need. This package provides the steam-native script, which launches Steam with the STEAM_RUNTIME=0 environment variable making it ignore its runtime and only use system libraries. The steam-native-runtime package depends on over 130 packages to pose a native replacement of the Steam runtime, some games may however still require additional packages. Warning: Using the Steam native runtime is not recommended as it might break some games due to binary incompatibility and it might miss some libraries present in the Steam runtime. the OpenAL version of the Steam runtime lacks HRTF and surround71 support.
