Raspberry Pi

[Hilmer]

Hi

I have been watching the videos on running Erlang (which I love) on
the Pi (of which I own one).
So I would like to do that my self. I'm not too familiar with setting
up a cross-compiler (although I have done it once years ago).

Is the recipe for compiling Erlang for the Pi the one mentioned here:
https://github.com/esl/erlang-embedded
Or is this bitbake/OpenEmbedded route for other that Pi architectures.
I see the last change was more than a year ago.

To at least do something.
I tried to build a minimal Erlang using this script:
https://github.com/Gustav-Simonsson/Stripped-Erlang
But it does give me handful of errors after building Erlang along this
line:
Error: no such file "Compressing appmon-2.1.14.1"
...
And before them:
strip:erts-5.9.1/bin/erl.src: File format not recognized
strip:erts-5.9.1/bin/start_erl.src: File format not recognized
strip:erts-5.9.1/bin/start.src: File format not recognized

How small should the stripped Erlang be roughly?
My resulting tar.gz is around 17M.

What do you recommend to get Erlang flying on my Pi

Okay

I got a lot further, managed to set up a cross-compilation for the Pi, and cross-compiled the ncurses library needed by Erlang.

Then I followed this guide: http://www.erlang.org/doc/installation_guide/INSTALL-CROSS.html

And this succeeds until step (4): make install DESTDIR=<TEMPORARY_PREFIX>

When I issue that command it fails after a while with:

/usr/bin/install -c -d ./for_pi/usr/local/lib/erlang/lib/mnesia-4.7/examples/bench

(cd bench; /usr/bin/install -c -m 644 \

and my supplied DESTDIR contains nothing but empty directories.

Any ideas what I can do to get past this?

I'm planning on using Pi as an Erlang server for a couple projects.

I just received my Pi this week. I installed the default Debian Squeeze image.
Once I got SSH enabled, I did:
  sudo apt-get update --fix-missing
  sudo apt-get install erlang --fix-missing
and waited. When the dust settled, I had a working Erlang shell.

Now to run the test suite. I'll post results when I have them.

Thanks whoever did the work!

Aaand I just noticed that doing it this way gets me version 14, not 15.
For my purposes, this should be OK, but your mileage may vary.

Nice, but I would really like to know how to cross-compile erlang my self.

The Pi is just a first :-)

But thanks for the information
