This should be in your test.h, and the declaration can be omitted.
Templates have to be defined at compile time. When they are instanciated 
(used) the compiler will create the appropriate function. So a function 
test<int> can be defined in more than one object, but this is no fault and 
the linker will pick one definition of the function and drop the rest. 
That's it.
