Eclipse giving error where CMake gives none

I have a

class const_iterator: public std::iterator<std::random_access_iterator_tag,
            int>
    {
        ...
    }

that cmake compiles just fine, but Eclipse is saying Invalid template arguments. It took me a long time to find all the include directories for Eclipse to compile the code in, and I finally ended up with

"Search for Unresolved Includes" doesn't show anything anymore, but I'm guessing the problem might be that since locate gave multiple locations for some of the files I was searching for, I might've picked the wrong folder to give to Eclipse.

Anyone know how I can compare the entire include paths of Eclipse vs automake, or know what the real problem here is?

Thanks!
