https://bugs.freedesktop.org/show_bug.cgi?id=59296
Priority: medium
Bug ID: 59296
Assignee: dri-devel@lists.freedesktop.org
Summary: libGL cannot load r600_dri unless application itself
is linked to libstdc++
Severity: normal
Classification: Unclassified
OS: All
Reporter: rankincj@googlemail.com
Hardware: Other
Status: NEW
Version: git
Component: Drivers/Gallium/r600
Product: Mesa
I have just tried to play WoW using the latest 64 bit Mesa from git, and have
noticed that libGL refuses to load the r600_dri object, complaining that:
libGL error: dlopen /usr/local/lib64/dri/r600_dri.so failed
(/usr/local/lib64/dri/r600_dri.so: undefined symbol:
_ZTVN10__cxxabiv120__si_class_type_infoE)
libGL error: unable to load driver: r600_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: r600
libGL error: Try again with LIBGL_DEBUG=verbose for more details.
The symbol _ZTVN10__cxxabiv120__si_class_type_infoE is from libstdc++, which is
not listed as a dynamic dependency of r600_dri. Since wine64 doesn't have a
dynamic dependency on libstdc++ either, the dynamic linker does not know how to
resolve this symbol.
After I had relinked r600_dri against libstdc++, WoW-64.exe was able to run
successfully.
