Oops, just tried. I got the same compilation error, so it is not your building environment.

Since you just get started, I would recommend work on 4.02.3. Multicore will be just one piece of the whole OCaml eco-system, so you can hone your skills on the rest for now. And many tools still have problems with 4.03.0 (Batteries is released today for 4.03.0, yeah!) and certainly you don't want to deal with these overhead when you just get started.

Anyway, welcome to the list.

Sorry to disappoint you, but there is no multicore support in OCaml, yet.
At least, in a form which which is suitable for beginners. (Cause you can span a thread from C, or use a very-very devel branch which supports it)

As for ocaml-top you either switch to a version where it compiles (4.02.3) or wait until ocp-index get fixed.

I'm new to OCaml and trying to get started by getting ocaml-top installed.

I really want to use 4.03.0 because I really want to have all my experience with OCaml be with multicore OCaml (I had a list of criteria that I was looking for in my next language, and OCaml was almost perfect until multicore support came along - when it came along, that made it perfect and worth overcoming the inertia of trying to switch from my current language of daily use).

Unfortunately, ocaml-top has ocp-indent as a dependency, and when I try to install ocp-indent, I get the following error. If this is due to a known issue, let me know and I'll wait for a fix. If this is due to some issue with my build environment, please direct me to appropriate resources for figuring out how to remedy this problem.

Furthermore, if there are good resources or tips for helping to determine when a problem is a build environment issue as opposed to an issue with an existing package that just needs to be updated, please let me know what they are.

Thanks,
Andrew
