[Insight-users] Compilation error when using Insight header files and gcc4.5

[Bill Lorensen]

The error says that you are violating one of the concepts required by
this filter. IN your case, the output pixel type is probably declared
as float. The connected component image filter requires an integral
outpu data type.

That said, your vtkITK code is probably trying to instantiate the
filter over the range of types that VTK supports. These types include
float and double, which are not integral.

Did you get vtkITKIslandMath.cxx from Slicer3. In the version of that
code that I have, I do not see and float or double instantiations.
Perhaps you are using an old or modified version of that code?
