Luis,

Changing fltk to build with multithreaded dlls was the trick.  You application now builds and
executes.  What type of data can I throw at it?

One concern I have is that in building fltk with multithreaded dlls, the fltk distributed examples no
longer build. Most of their examples have link errors for undefined symbols __argv __argc.  Have you
seen this before?

Jim

Sounds good, I'll add them.

BTW it is a bit odd to have to add these directories in several places.
Now they are in :

Unsupported/FltkImageViewer/CMakeList.txt
Unsupported/MetaImage/IView/CMakeList.txt
Examples/GaussianFilter/CMakeList.txt
Examples/ImageRegistration/CMakeList.txt

Is there a way to put them in a central place ?

I did a similar thing, maybe we should add that to the README file
since is something that has to be done by hand.

It is due to the flags that should be activated in FLTK.
All the libraries we use have to be compiled with exactly the same
compiling options:

Debug Multithreaded DLL
struct member alignment 8 bytes
Exceptions enabled
RTTI enabled

and so on...

You'll have to recompile FLTK using the ITK setup.


You should not need the /NODEFAULTLIB option...

I'm not having this problem with the GaussianFilter example,
but with another external project,... and the cause seems to
be the same.
