And it is just a case of a missing ITKCommon_Export. It's just a little tricky because you have the non-specilized declaration and definition. Then a specialized declaration. What's missing is a statement which says the method has been explicitly instantiated (this just happens to be a totally specialized version), but the statement is that same as if it'd been explicitly instantiated. This has been compiler dependent, and we use the ITKCommon_EXPORT macro for that. It's sounds like the extern keyword should to this in C++0x, but I hadn't looked at the closely.</div><div><br></div><div>I hope this help explains what's going on....</div><div><br></div><div>Brad</div><div><br></div><div><br><div><div>On Mar 15, 2013, at 10:31 PM, Bill Lorensen <<a href="mailto:bill.lorensen@gmail.com">bill.lorensen@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">There are issues with template specializations and -fvisibility=hidden.
