[Caml-list] ocaml-top on 4.03.0 ?

[Caml-list] ocaml-top on 4.03.0 ?

[Andrew Shi-hwa Chen]

[-- Attachment #1: Type: text/plain, Size: 2362 bytes --]

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

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.

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.

Hi Andrew,

A patch was delivered yesterday, so run `opam update` before `opam install
ocp-indent`. You should be able to install without problem now.

Indeed, from
http://opam.ocamlpro.com/builder/html/report-last.html#ocaml-top,
ocaml-top.1.1.2 works on all versions >= 4.00 since yesterday.
I also upstreamed a patch to make ocp-index work on all 4.01,4.02 and 4.03.
