Ruby on an embedded ARM processor

ruby-talk
1

Hi all,

I’m doing embedded linux development, and while a lot of the code I write has
to be in C, I’d really like to be able to run my favourite language on the
device. So two questions:

  1. Has anybody ported Ruby to an ARM (or ideally Intel XScale) processor?

If so, I can run the cross-compiled version out of an NFS mounted share

  1. Is there a trimmed-down distribution that could fit in under 5MB?

If so, then I can actually distribute Ruby with the system and not just use it
for testing/debugging.

Thanks in advance,

Ben Giddings

Since you’re developing in C, presumably you have a cross-compiler? Why not
just try firing it up on the Ruby source.

If your run-time environment is reasonably POSIX-compliant, and your compile
environment has a POSIX shell (to run ./configure) and an ANSI compiler, you
may be in luck.

  1. Is there a trimmed-down distribution that could fit in under 5MB?

On my FreeBSD box, /usr/local/bin/ruby [version 1.6.8] is 1.4MB, and
/usr/local/lib/ruby/1.6 is 3.6MB [of which 2.1MB is libruby.a, which you can
drop if you don’t want to embed Ruby in other C apps]. So unless the ARM
machine-code is much more bloated than the i386, you should easily get a
full Ruby distribution in around 3MB.

Cheers,

Brian.

Why not
just try firing it up on the Ruby source.

I’ll try that, I just wanted to know if anybody had already shown that
cross-compiling to ARM would work. In my recent experience, cross
compiling can be dead easy, or a major headache, and I just wanted to
know which end of the spectrum Ruby was on.

If your run-time environment is reasonably POSIX-compliant, and your
compile
environment has a POSIX shell (to run ./configure) and an ANSI
compiler, you
may be in luck.

My cross-compile environment is i386 Linux, my runtime environment is
ARM-linux, so I should be ok there.

  1. Is there a trimmed-down distribution that could fit in under 5MB?

On my FreeBSD box, /usr/local/bin/ruby [version 1.6.8] is 1.4MB, and
/usr/local/lib/ruby/1.6 is 3.6MB [of which 2.1MB is libruby.a, which
you can
drop if you don’t want to embed Ruby in other C apps]. So unless the
ARM
machine-code is much more bloated than the i386, you should easily get
a
full Ruby distribution in around 3MB.

Ok, what does /usr/local/lib/ruby/1.6 contain? Does it contain network
classes? Aside from the core classes that’s the part I need. If it
does contain that, can I trim any of the other parts (Complex, OO
classes, etc) out?

Hmm, perhaps you might like to install Ruby on your Linux workstation so you
can play with it :slight_smile:

Below is what I have. You’ll note that most of it consists of libraries
written in Ruby, but the C compiled stuff is in
/usr/local/lib/ruby/1.6/i386-freebsd4.8 (including socket.so, which you were
asking about)

You could trim it at your own risk - i.e. you would have to be sure that you
did not remove any library which any other library depended on.

I’m not sure if Linux has a compressed filesystem, but that might be another
option (Ruby source, being plain text, should compress pretty well)

Brian.

I’m not sure if Linux has a compressed filesystem, but that might be another
option (Ruby source, being plain text, should compress pretty well)

From kernel-doc-2.4.18/filesystems/cramfs.txt:

Cramfs - cram a filesystem onto a small ROM

cramfs is designed to be simple and small, and to compress things well.

man lsattr chould help :slight_smile:

cramfs is designed to be simple and small, and to compress things well.

the “familiar” Linux distro (from iPAQ/handhelds.org fame) uses
jffs2 for the internal flash (based on the mtd block interface; do not use
it on flash with an IDE interface).
Jffs2 is not only compressed, but also writable and still saves your flash.

The Ruby packages in familiar are thus compressed.

Yeah, it’s JFFS2 I’m using.
