Is anyone else interested in this, or even already working on it?

    Yes! i am interested. But is there anything that needs to be done
for it? I mean i was able to build/run guile without any problems in
scratchbox/maemo env. Would you want .debs for it or there are things
that needs porting?

For core Guile no, I guess not.  But I would personally like a
Hildon-enhanced guile-gnome as well, so that I can play with writing
small graphical apps.  I think this means adding defs for the Hildon
API to the existing gtk/gnome defs, and then rebuilding guile-gnome.

I see that the PyMaemo people have already prepared a load of Hildon
.defs files.  Does anyone know whether these are valid verbatim for
guile-gnome as well?

Did you have to build GMP first?  Perhaps GMP is already included in
the Maemo env.

> Would you want .debs for it or there are things that needs porting?

We'd want to end up with .debs, yes.  Do you already have these?
(I've never done this before myself; my impression is that the process
is a bit fiddly, but not too hard.)

I wouldn't expect anything to need porting except for the Hildon API
graphical stuff mentioned above.

Thanks for your reply!

   Oh! guile-gnome is seperate story, you should have made it explicit! :)

   I think Rotty or Wingo can answer that. I don't know anything about
gwrap and therefore guile-gnome internals.

   GMP? What is that? :) I don't rememeber needing to install anything
other than what was already installed by sb/maemo but it was a few
months ago and i can be wrong.

   I did create the debs and tested them too but I don't have them
anymore. :( But it was easy and i can make them again. But is there
really a need? The .debs for guile provided by the official debian arm
repos. works out of the box.

   I don't think that requires any 'porting', we just need to wrap the
hildon widgets. I can start to work on this but first i'll need to
learn goops and g-wrap.

> Thanks for your reply!

   No problem. :)

The GNU multiprecision arithmetic library, which is a dependency of
Guile 1.7/CVS.

Were you building 1.6, or 1.7/CVS?

Oh, that's nice, I didn't think of that.  How do you make the normal
Debian .debs install to the right location, though?  Presumably the
Debian .debs install with prefix /usr, and I thought that Maemo
required some odd prefix like /var/lib/install?

(Also, if the Debian .debs work out of the box, why did you try to
build in scratchbox, out of interest?)

Please let me and the list know if you make progress on this, so that
we don't duplicate effort.

   IIRC, it was 1.7. I really need to do it again to be sure on what happend.

   If you use the application installer, yes! I didn't use the
application installer to install the packages so there was no problem
at all. Thanks for pointing this out, i think this might produce some
problems.

   The same reason you aske the question, 'curiosity' :)

    Yeah sure!

Uhh, the circle closes! :-)

In my other life, I am working for Nokia on the 770 and at some point
I of course compiled Guile for it.  It was a no-brainer as far as I
remember.

In fact, I would be the official Nokia guy handling all kinds of
'languag binding' issues for hildon, etc...  Guile is not specifically
in our plans, but language bindings are.

    So i assume you'll be taking care of this?

What would be "this", exactly? :-)

I am not going to write Guile/Hildong bindings myself in the
foreseeable future.

   Porting of guile to maemo/770 and making debian packages for it.

    OK! i think i'll try to do this part.

That's interesting, I tried to build CVS and hit a problem running
./configure:

checking for lt_dlinit in -lltdl... no
configure: error: libltdl not found.  See README.

Is there an easy fix for this?

(I believe this arises from the following lines in configure.in:

AC_CHECK_LIB([ltdl], [lt_dlinit], ,
  [AC_MSG_ERROR([libltdl not found.  See README.])])
)

A fine reason indeed.  Thanks for explaining.

Not for me unfortunately ... but I've written about that in another
post.

I for one completely understand that you have to distinguish between
your Nokia role and your Guile role.  It would be cool if Guile/770
users could contribute enough to change the official plans, but let's
see ...

        Neil

I guess you 'just' need to install libltdl3-dev or similar into your
scratchbox environment.  Unfortunately, I don't know how this works
with the official maemo SDK (we use slightly different stuff in house;
yeah, we should eat our own dog food... ;).  Maybe you can just
"apt-get" it, or maybe you need to compile libtool from source.

Guile does not distirbute a copy of libltdl, since that would create
more trouble than it solves, in my experience.  (We could include a
copy of libtool for convenience, but we should not try to build and
install it during a normal Guile build/install.)

Thanks, that reminded me that I'd seen something about a Debian
repository in the Maemo developer pages.

But...

[sbox-SDK-PC: ~/guile-cvs-head/guile-core] > fakeroot apt-get install libltdl3-dev
Reading Package Lists... Done
Building Dependency Tree... Done
Package libltdl3-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package libltdl3-dev has no installation candidate

This is getting a bit off-topic for Guile, so I'll ask on the Maemo
list as well.

Regards,
    Neil

For any 770 owners out there...  I now have a set of Guile .debs for
the 770, including Hildon bindings, and have been using them
successfully for some time to play with writing GUI apps on the
tablet.

Details are at http://www.ossau.uklinux.net/guile/index.html

Impressive!

I look forward to playing with this.
