I think it's a matter of approach. Since the Java API uses JNI to pick up the C++ libraries, the state of the C++ libraries rather matters. And to quote Microsoft itself: "Like a statically linked library, a DLL exports variables, functions and resources by name, and your app imports those names to use those variables, functions and resources. Unlike a statically linked library, Windows connects the imports in your app to the exports in a DLL are load time or at run time, instead of connecting them at link time. // Windows requires extra information that isn't part of the standard C++ compilation model //. The Visual C++ compiler implements some Microsoft-specific extensions to C++ to provide this extra information. the marked sentence is what George is referring to, unless I've got it wrong - you have to mark up everything that's to be "exported" from the library before it works. That's rather a pain... -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
