Your makefile has a rule to build "edit" but you seem to want a target called "hello" -- why is your rule building "edit" instead? It will work if you just change "edit" to "hello" or vice versa. Also, your rule for "all" is invalid, "-std=c++0x" is not a valid rule, I don't know what you meant that to be.
