Let me add my 0.01c... The only official way sanctioned by the upcoming C++ ANSI/ISO standard to instantiate templates is to explicitly mention the types you want to use for instantiation. All of the repository techniques that exist, some better, some worse, are not standard and that's one reason why you do this differently on each platform. If you ask me, explicit instantiation is the correct way, because it gives you the control on where, when and how many times (hopefully just once!) you instantiate something. If your compiler supports explicit template instantiation with the standard 'template class MyClass<int>;' mechanism (as g++ appears to), then this is what I would do: 1. Put the class declaration in a header file by itself. 2. Put the class definition in a source file by itself. 3. Put the template instantiation at files where you actually use the template. Preferably, put them in a file just by themselves; this way, it is easier to control whether you have instantiated a template or not. 4. It is important not to mix templated code and non-templated code in one file (as in point (2) above); this way, you avoid multiple definitions just because you instantiate two templates of the same class with different type parameters on two separate files. Hope this helps. -- Gonzalo A. Diethelm G. [EMAIL PROTECTED] -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] . Trouble? e-mail to [EMAIL PROTECTED] .
