hey guys

When i try to make the following mutating method inline i get the
following error:
//method
inline void vertex::setValue(int new_value) throw() { value_ =
new_value; }

When you try to make the function inline WHERE?

error LNK2019: unresolved external symbol "public: void __thiscall
vertex::setValue(int)" (?setValue@vertex@@QAEXH@Z) referenced in
function _main

removing the inline keyword fixes the problem
any advice would be much appreciated

The definition of the inline function must be in file that is
#include'd by every source file that uses. Not in a separate source
file that has the body of non-inlined functions.

The compiler can only generate inline code for a function when that
function's definition is in scope when the function is called.
