You mean with something like

extern template void resizeG(Vector<Point<float,3> >& , int );

is that what you mean by having the explicit instantiation in the
header? 


By the way, if I remove the namespace and just use

template<> void resizeG(Vector<Point<float,3> >& , int ){ cout <<
"B";}


It works with no problem (output of program is B and not A).

However, it behaves as I described with the namespace. Why is the
namespace creating problems ?

Thanks for the reply.
