[vtkusers] undefined reference to `__builtin_va_start'

[Paul McGuinness]

Hi Developers,

I have just installed vtk-4.2.2 on a new machine (Linux), and when I
compile any
of the examples that worked on my previous machine (again Linux) I get
this compilation error:

Building object file mummy.o...
Building executable mummy...
/usr/local/lib/vtk/libvtkCommon.a(vtkTimerLog.o): In function
`vtkTimerLog::FormatAndMarkEvent(char const *,...)':
vtkTimerLog.o(.text+0x196): undefined reference to `__builtin_va_start'
collect2: ld returned 1 exit status
make[1]: *** [mummy] Error 1
make: *** [default_target] Error 2

Does anyone know what this means? I am utterly bewildered by this error.

Thanks,
Paul.
