Splitting templated C++ classes into .hpp/.cpp files--is it possible?

Question

I am getting errors trying to compile a C++ template class which is split between a .hpp and .cpp file:

$ g++ -c -o main.o main.cpp

Sometimes it is possible to have most of implementation hidden in cpp file, if you can extract common functionality foo all template parameters into non-template class (possibly type-unsafe). Then header will contain redirection calls to that class. Similar approach is used, when fighting with "template bloat" problem.
