Matt, On windows if no export/import is declared for a symbol it will be considered internal and not specified in the windows DLL interface. A similar things should be done with default visibility with gcc. So this "should" not occur.
This particular issue should have been resolved with this patch: https://github.com/Kitware/ITK/commit/395420846e0c9e48ede28f84a59794d889b51724 Brad On Jun 3, 2013, at 11:30 AM, Matt McCormick <[email protected]> wrote: > Hi Brad, > > Duplicate exports may be an issue.
