Use Compiler/Linker for C++ Code Clean-up

Question

I'm using VS2008 for a C++ project. The code is quite old and has passed through many hands. There are several classes hierarchies, functions, enums and so on which are no longer being used.

Is there a way to get the compiler/linker to list out identifiers which have been declared or defined but are not being referred to anywhere?

Answer 1

VS will warn about identifiers declared within a function and not used, you may need to move to warning level 4, but for global variables, and a hunt for many other potential problems, you would do well to try lint or visual lint

Answer 2

PC-Lint "whole project" analysis (which analyses multiple files together) can do this. Please feel free to contact me if you need help setting it up.
