Priority: medium Bug ID: 78242 Assignee: dri-devel@lists.freedesktop.org Summary: Steam cannot load mesa drivers (libGL error: driver pointer missing) Severity: normal Classification: Unclassified OS: All Reporter: laszlo.kertesz@gmail.com Hardware: Other Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
I rebuilt mesa recently (on Debian Testing 64 bit) an i see that Steam is broken again. I get this in a terminal (accompanied by a graphical popup saying "OpenGL GLX context is not using direct rendering, which may cause performance problems.") :
Running Steam on debian 64-bit STEAM_RUNTIME is enabled automatically Installing breakpad exception handler for appid(steam)/version(1398120891_client) libGL error: dlopen /usr/lib/i386-linux-gnu/dri/r600_dri.so failed (/media/bigdata/games/.steam/steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libgcc_s.so.1: version `GCC_4.7.0' not found (required by /usr/lib/i386-linux-gnu/dri/r600_dri.so)) libGL error: unable to load driver: r600_dri.so libGL error: driver pointer missing libGL error: failed to load driver: r600 libGL error: dlopen /usr/lib/i386-linux-gnu/dri/swrast_dri.so failed (/media/bigdata/games/.steam/steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libgcc_s.so.1: version `GCC_4.7.0' not found (required by /usr/lib/i386-linux-gnu/dri/swrast_dri.so)) libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast
Then other Steam specific stuff. The Steam GUI launches but cannot launch anything.
Now i dont know what is the issue here since i built Mesa this way since a very long time ago, with my current (gcc 4.8) compiler and had no such issues.

Other 64 and 32 bit opengl games seems to work fine.

--- Comment #2 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- Lastest update of fedora rawhide triggered this bug.
If I understood well, the steam preloaded libs use a different libgcc than the system dependent libs.
Anyone told valve to tidy that thing?

It's a steam bug, not a mesa one
I disagree: this (naïvely linking LLVM) is a change in mesa that breaks many binary software packages, not just Steam. While the steam-runtime will likely get a fix for this at some point, some older games may not be so lucky.
Packaging libstdc++ and libgcc_s is relatively common with binary software packages targeting Linux - it is practically required in order to target a wide range of distribution versions while not limiting yourself to an ancient compiler. Here is a small list of such packages that I happen to have installed which bundle those libraries:
$ find /{opt,usr/local/games}/ ~/Games/Trine/ -name 'libstdc++*' -o -name 'libgcc_s*' /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/intel64/pinruntime/libgcc_s.so /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/intel64/pinruntime/libstdc++.so /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/intel64/pinruntime/libstdc++.so.6 /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/intel64/pinruntime/libstdc++.so.6.0.10 /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/intel64/pinruntime/libgcc_s.so.1 /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/ia32/pinruntime/libgcc_s.so /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/ia32/pinruntime/libstdc++.so /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/ia32/pinruntime/libstdc++.so.6 /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/ia32/pinruntime/libstdc++.so.6.0.10 /opt/intel/composerxe-2013.2.144/bin/sourcechecker/lib/ia32/pinruntime/libgcc_s.so.1 /opt/quake4/libstdc++.so.6 /opt/quake4/libgcc_s.so.1 /usr/local/games/sacred/lib/lib1/libstdc++.so.6 /usr/local/games/sacred/lib/lib1/libgcc_s.so.1 /usr/local/games/x2/lib/lib1/libstdc++.so.6 /usr/local/games/x2/lib/lib1/libgcc_s.so.1 /usr/local/games/postalx/postal2game/System/libstdc++.so.5 /usr/local/games/postalx/postal2game/System/libgcc_s.so.1 /usr/local/games/postalx/postal1game/libstdc++.so.5 /usr/local/games/postalx/postal1game/libgcc_s.so.1 /usr/local/games/aquaria/libstdc++.so.6 /usr/local/games/aquaria/libgcc_s.so.1 /usr/local/games/lugaru/libstdc++.so.6 /usr/local/games/lugaru/libgcc_s.so.1 /usr/local/games/survivor/lib32/libstdc++.so.6 /usr/local/games/survivor/lib32/libgcc_s.so.1 /usr/local/games/shadowgrounds/lib32/libstdc++.so.6 /usr/local/games/shadowgrounds/lib32/libgcc_s.so.1 /usr/local/games/coldwar/lib/libstdc++.so.6 /usr/local/games/coldwar/lib/libstdc++.so.6.0.8 /usr/local/games/postal2/System/libstdc++.so.5 /usr/local/games/postal2/System/libgcc_s.so.1 /usr/local/games/braid/libstdc++.so.6 /usr/local/games/braid/libgcc_s.so.1 /usr/local/games/testtool/lib/lib1/libstdc++.so.6 /usr/local/games/testtool/lib/lib1/libgcc_s.so.1 /usr/local/games/prey/libstdc++.so.5 /usr/local/games/prey/libgcc_s.so.1 /home/dscharrer/Games/Trine/lib32/libgcc_s.so.1 /home/dscharrer/Games/Trine/lib32/libstdc++.so.6 /home/dscharrer/Games/Trine/lib64/libstdc++.so.6
This has not been a problem in the past as system libraries (those you effectively have to link against to make full use of the hardware) have refrained from pulling in either of the GCC libraries. In fact, the only one I found doing this besides mesa is XvMC:

This search includes fglrx's libGL by the way: The proprietary AMD (and I'm sure NVIDIA) drivers have long used C++ internally, but have taken care not to pollute the global namespace with the C++ standard library or GCC helper library. I think this shows even more precedent that these libraries should not be considered safe to use in base system libraries without additional precautions.
What you are doing here is introducing additional problems where none existed before. Please reconsider statically linking libLLVM and required C++/GCC libs into *_dri.so or finding some other solution to not conflict with programs loading libGL. (An even stricter RTLD_LOCAL that completely namespaces libs would be nice to have here …)
For reference, here are a few more bugs caused by this: #30192, #30901, #38182, #38783, #43964, #66955

I would say that both parties are to "blame" on this one. AFAICS the topic of to ship libgcc_s/libstdc++ or not has always been a interesting one.

I beg to disagree here. Mesa has linked against libgcc_s and libstdc++ since forever. Whereas the static/shared linking against LLVM has always been a configure time decision.
Please reconsider statically linking libLLVM and required C++/GCC libs into *_dri.so or finding some other solution to not conflict with programs loading libGL. (An even stricter RTLD_LOCAL that completely namespaces libs would be nice to have here …)
Static linking against gcc/c++ seems like a bit of a pain as libtool, unconditionally appends "-lgcc -lgcc_s -lstdc++" (as defined by postdeps), thus -Wl,--static.. and/or -static-lib{gcc,stdc++} does not really help.
If you have any solid suggestion please put them forward.
