Compiling and #include not seeming to have an effect

I have a class called Human it is defined in Human.h and implemented in Human.cpp.  Now Have another class called LoosenCommand.  In LoosenCommand.h I have a #include "Human.h"  then the constructor for LoosenCommand takes a Human*.  When I do  CC on LoosenCommand I get Human is undefined?  Why is this?  I seemed to have fixed it using class Human; declaration at the top.  It now compiles but as soon as the refrence to a Human is hit in LoosenCommand it crashes, so that leads me to beleive that I have just told the compiler Human will be declared later, but LoosenCommand never finds it.  So how do I do this?

Try using the full path to Human.h in the #include statement in
LoosenCommand.h.  You can use a make file where all dependecies
are expressed.

if the compiler does not find the intclude file it will probably produce an error saying so.  In any case, it will not compile so that is not likely to be the cause.

Yes, agree with nietod; the makefile wouldn't help anyhow jstegall; and micah, when you say ''it crashes'', what exactly does it do?  You mean ''I get a compiler error''?
