The project cc files know you have a template <dim>, but does not know
what values dim can actually take; except that it will be an integer. You
need to tell the machine to instantiate for the dim values you want to
use; ie. 1, 2, 3, 4...
To do that stick instantiations at the end of your cc files like this:
> ADEquation.cc-------------------------------------------------------------------

// Here are the instantiations:
template class ADEquation<2>; // This is for 2d implementation.
template class ADEquation<3>; // This is for 3d implementation.
You only need to instantate dim (or any other template variables) for the
ones you want to use. Of course, you will need to do that for all classes
you have. Looks like you have a cdGMethod class to, is that <dim>
dependent? If so, do it, if not, no.
That should keep the linker happy.
Clear?
Best,
Toby
