C++: why can't i make a queue of a struct?

Question

I have the following code:

        #include <queue>
        struct Job                  
        {
        };
        queue<Job> _jobQueue;

But I get the error:

error: ISO C++ forbids declaration of âqueueâ with no type

How can I make a queue for my struct?

(Note that names beginning with a leading underscore followed by a capital letter are reserved for the implementation -- the leading underscore is generally avoided for this reason. — Billy ONeal

Also, all names with global scope that start with an underscore are reserved - such as _jobQueue in this fragment. — MSalters

You didn't #include <queue>.

EDIT: After your edit, you need to qualify that as std::queue<Job>.

forgot to put that in the example, but not the issue here :(

@Garrett: Yes, it is. Check your includes; check that you're qualifying in the std namespace as required.

Try the following

std::queue<Job> _jobQueue;
