Maybe I don't understand your problem sufficiently.  But I'll open my
mouth anyway.  I thought the whole point of templates was to
automagically instantiate all classes.  I'm using a recent version of
g++ with heavy template use and have experienced no problems (at least
none attributable to the compiler).

Have you told g++ to use the other-than-default template instantiation
model?  Are you doing any "#pragma interface" and "#pragma
implementation"?

Perhaps you could post a minimum-code example that recreates your
problem?
