[Insight-developers] In the spirit of the green dashboard

[Wes Turner]

All,

I have been trying to track down an issue with the dash14 cygwin build on
the dashboard.  For some reason we are getting multiply defined symbols in
vnl template instantiations.  The symbols are defined in both the
libITKCommon and libitkvnl libraries.  I included one of the error messages
from the dashboard ... there are 50 more just like it.  The dashboard entry
is dash14.kitware
Win32-cygwin344.<http://www.cdash.org/CDash/buildSummary.php?buildid=336834>
The error began occurring on or about May 7th.  I reviewed the check-ins
around that time and am not seeing an obvious candidate.  I reverted the ITK
code to the day before the failing submission and then to one day earlier
than that, but I still get the error.  I am not seeing any obvious changes
to the build environment.

So, this afternoon, I cleaned out both the source and binary directories and
am waiting with bated breath to see the results.

If anyone has suggestions, or if anyone has a working cygwin build they can
submit as an Experimental it would be appreciated.  Of course, there is an
outside chance that clearing out the source directory will help, but I have
my doubts.

Thanks for any help,

- Wes
