inline function linker error

Question

I am trying to use inline member functions of a particular class. For example the function declaration and implementation without inlining is as such:

in the header

Answer 1

from C++ FAQ Lite

If you put the inline function's definition into a .cpp file, and if it is called from some other .cpp file, you'll get an "unresolved external" error from the linker.

How do you tell the compiler to make a member function inline?
