The issue is with "dllexport": previously, dllexport was present on exposed templates tool (= visibility(default) for gcc/clang). This ensured MacOS compatibility since then the typeinfo is corretly shared and dynamic_cast/typeid works. For Windows, the "dllexport" equivalent requires the template instantiations to be declared "external" which is a coding nightmare. The solution is to provide separate macros for real (non-specialized, not explicitly instantiated) templates (.._PUBLIC_TEMPLATE) which is defined as empty for Windows and "visiblity(default)" for gcc/clang. |
