[Rtk-users] Linking error with rtkLookupTableImageFilter.h

[Simon Rit]

Hi,
I didn't manage to reprocude your problem quickly but my guess is that
the problem is that the template specializations in this class have
not been declare inline. Can you try to use the attached file,
recompile RTK and then your software to check if this solves the
problem?
Thanks for the report and please don't hesitate to report your other
'shared libs option' bug.
