[Splashy-devel] Bug#453349: Information about splashy FTBFS

[brian m. carlson]

__vdso_clock_gettime is a fast version of clock_gettime that lives in 
the Linux VDSO (linux-vdso.so.1 on amd64), which is a dummy library that 
is part of the kernel (and mapped by the kernel into every process's 
address space).  Thus, ld will never be able to look it up, since it 
doesn't exist outside of the kernel binary.

This bug will only manifest itself on architectures that have the VDSO, 
which (TTBOMK) are i386 and amd64.

There are two ways around this: either don't link statically, or create 
a weak symbol for __vdso_clock_gettime.  I have not tested the latter, 
and so I am not sure if it would work.  Either way, I am of the opinion 
that this is a glibc bug, and so it should probably be reassigned there.
