Hi, When I build hb as a dll, it does not export any symbol. I had to the project to add a .def file I stole from the hb-shape win32 compiled example. But I don't know what the proper way to get the symbols to be exported is. These are the options I used to compile HB: WIN32;_DEBUG;_WINDOWS;_USRDLL;HARFBUZZ_EXPORTS;HAVE_OT;HAVE_UCDN Regards!
