[Insight-developers] linker won't build new library

[M Stauffer (V)]

Hi Luis,

0) The source file actually has the itkArray1DToDataTest(int, char* [])
signature. Seems the linker just reports it as "char **".

1) I'm not building with shared libs. That is, cmake option
BUILD_SHARED_LIBS is off. But the class is declared with ITK_EXPORT
anyway.

The repo is available here: git at github.com:picslITK/ITK4_topics.git
The branch is RegRefactoringStaufferWorking
The files are:
Modules/Registration/Refactoring/src/itkArray1DToData.cxx
Modules/Registration/Refactoring/include/itkArray1DToData.h

Thanks for taking a look. I can't see what I'm missing in terms of cmake
config. I've also tried a clean build, but that's not helping.

Cheers,
Michael
