OCaml on Maemo

OCaml on Maemo

[David Allsopp]

My shiny new Nokia N900 has finally arrived so, of course, having got bash,
vim and texlive successfully installed I naturally need a compiler!

Before I dig into trying to compile OCaml on Maemo 5, can I ask if anyone
else out there has already tried (and hopefully succeeded)?

Hi,

On my N810, thanks to the "easy debian" technique:
http://wiki.maemo.org/Easy_Debian

I got access to all the ocaml packages which are available on debian-ARM.
Everything I tried worked perfectly (but I only tried "text mode" apps).

Yes, I've tried similar years ago on the N800 (Maemo 4, however). I ran
into this problem at that time:
http://caml.inria.fr/mantis/view.php?id=3746. The ARM code generator was
changed since then (will be released in Ocaml 3.12). Haven't tried that
yet, though.

So far I remember the byte code compiler was no problem at all. Only the
native-code compiler had these problems with FP instructions.

No, I've mostly been playing with Vala since I got mine, but I'd love
to hear how you manage with it. It's definitely on my to-do list.

Hi,

I have an application that I would love to run
on my N810. I know this is possible because it
has been done for Unison, including its GTK interface.

http://talk.maemo.org/showthread.php?t=27426

However, I haven't a clue on how this has been done.

It says 2.5Gb are needed, but this includes OpenOffice
and Firefox, which I don't need. Can you detail the
"easy debian" technique for installing ocaml in a lighter
way ?

GTK is part of mameo, so with luck, lablGTK should also
work. Have you tried ?

What I did is:
- followed their installation instructions
- just for fun, tried once in my life to lunch open-office on a PDA :)
- played with localepurge (apt-get install localepurge) and many apt-get
remove and apt-get clean, to make space to install ocaml & co

But you can provide your own debian tree or disk-image to the easy-debian
scripts (I did not try but they say so).

no I even removed all X11 packages.

And also camlmix and bracetax from sources.

That seemed a little heavy for the first day of having it but I've
bookmarked the link for the future!

I had the same experience with 3.11.2 - the error message from configure
could be better, but that won't matter once it's fixed in 3.12.0 (as you
say).

Enabling the SDK repository allowed me to install bash, make, gcc,
libc6-dev, tcl8.5-dev, tk8.5-dev and libx11-dev.

(aside, which probably demonstrates my ignorance more than a bug/problem in
anything: I've never used aptitude before - I was amused that installing gcc
doesn't automatically upgrade glibc to the dev version as you end up with a
C compiler which can't link. Couldn't quite imagine a situation where that's
handy but hey ho!)

OCaml 3.12.0+dev17 compiles out of the box (using -prefix /opt/maemo) -
ocamlbrowser works (i.e. labltk) and ocamlopt is fine. The reference run of
a command line app of mine takes 5 mins 20 sec (impressive as it takes 31
seconds on my Intel P8600 laptop and used to take about 4:30 on the machine
on which it was originally developed).
