IncludeChecker Wiki
Check for unused #includes in C++ source
Status: Alpha

Unused #includes in C++ source lead to unwanted dependencies and slower compile and link timings.
IncludeChecker finds most of these unused #includes using a simple heuristic: if you include a file, you need to use one or more symbols from it. If that's not the case, IncludeChecker will mark the #include as unused.
IncludeChecker is very customizable to be able to run as an automated task where it will fail as soon as an unused #include is detected.
Because of the simple heuristic it will not find all unused #includes, but it will find most of them.
