Does there exist topological spaces (in general) that are compact, but non-bounded?

I know that all compact sets are bounded in a metric space, but I was wondering if there exist some exotic topological space where this is not the case?

Cheers.

    How are you defining *bounded* in general topological spaces?2017-01-10

    If a topology isn't defined by a metric what do you mean by "bounded"?2017-01-10

    I'm not sure if such a concept exists. I guess I should have been clearer - my question implies that there is a generalization of "boundedness" beyond that of metric spaces!2017-01-10

    @Henry1981: There really isn’t a natural generalization of boundedness to topological spaces in general. It is possible to define a notion of total boundedness for uniform spaces.2017-01-10

    You can take a look at [Wikipedia: Bornological spaces](https://en.wikipedia.org/wiki/Bornological_space).2017-01-10
