There are issues with template specializations and -fvisibility=hidden.
>From what I read no current compilers officially support this, but most do.
I guess my gcc on the MAXC does not.
I'll put a patch to gerrit that adds lines like these in
Common/src/CMakeLists.txt
if(APPLE)
set_source_files_properties( itkArrayOutputSpecialization.cxx
PROPERTIES
COMPILE_FLAGS -fvisibility=default )
endif()
When I do this, my gcc build is OK.
