I'm using Ms Visual c++ and occasionally, when I make a class template, then go to link it with a driver file, I get unresolved externals error for some of the fuction templates in the class. So far, I've been unable to locate the problem... am I missing something?

======================================================================================== I don't know that this is the answer or not but you can get this kind of message when you attempt to link identifiers in your source code with an already established identifier/function within the module that is being linked in to your code (ie the driver in this case). In other words, the identifiers that you make reference to in your source (extern variables and functions) are not found anywhere outside of your source. The driver/dll/obj file(s) may not have those identifiers in the compiled code that they contain and therefore the compiler can only report this as an unresolved external. In the lingo of my home town in Boston they might say "yo, I can't find the orange you said was in dis crate". There are other possibilities but very remote ones at that. borelli34@cox.net John Borelli ========================================================================================
