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

[Luis Ibanez]

Hi Wes,

All the builds that I have attempted so far with Cygwin + gcc344 using
Shared Libraries ON result in the same set of duplicate symbols.

I attempted to repeat your experiment of going back in CVS time, and I
manage to get back to January 1st 2009 and still get the same link errors.

(Note that I have to update the two files to today

     /Insight/Utilities/gdcm
                    CMake/FindUUID.cmake
                    src/gdcmUtil.cxx


to get over the uuid problem.


I haven't find an explanation of why the build in dash14 is green on

May 8th
http://www.cdash.org/CDash/index.php?project=Insight&date=20090508

and

the link errors appear on May 9th
http://www.cdash.org/CDash/index.php?project=Insight&date=20090509


Despite the fact that locally, the link errors can be replicated as
back as January 2009.



It is interesting that in Linux, when building Shared, we produced
a shared libraries

              libitkvnl.so


while in Cygwin we produce a static library:

              libitkvnl.a

and a Common library

              cygITKCommon-3.11.0.dll

Records from the Developers mailing list indicate that for

   ITK 3.12: Dash14 was green except for a failing test
   ITK 3.10: Dash14 was green except for a failing test


It is not clear if at that time it was using Shared ON.
