Fwd: [Fwd: Virtaal on ARM]

[Chris Leonard]

All,

Ignoring for the moment whether parachutes or Mars-style airbags are a
better delivery option from helicopters, if one is going to "airdrop" an XO
tablet into a remote area, one of the things that might be very useful
would be the ability to bootstrap localization right on the machine.

I'm a big fan of Virtaal (from the makers of Poolte) as an off-line PO file
editor and general L10n tool for a variety of reasons I won't go into.

http://translate.sourceforge.net/wiki/virtaal/index

In previous interations of XO-1 builds, getting Virtaal on the Gnome boot
was a simple "sudo yum install virtaal".  Unfortunately, when I tried this
on an XO-1.75 with 883, I got errors (detailed far below).  I sent the
errors to the Virtaal devs and got back the reply in-lined below.

Can anyone shed some light on how it might be possible to get Virtaal
working on the Gnome boot on an XO-1.75?

Warmest Regards,

 OK so let me ramble a bit....

In the install: virtaal pulls in translate-toolkit which pulls in aeidon
aeidon is part of gaupol (gaupol is a subtitle editor aeidon implements the
subtitle formats)

The gaupol aeidon split happened during Fedora 14.  So in our
translate-toolkit RPM we only import aeidon when Fedora >= 14.

See ' %if 0%{?fedora} >= 14' at the top of:
http://pkgs.fedoraproject.org/gitweb/?p=translate-toolkit.git;a=blob;f=translate-toolkit.spec;h=6172c89bdaeceaf684c61a3750dca120ab72aa9e;hb=1e65541302d3c3bd217e4bd7b126d32be5b9c189

So from the looks of it OLPC pulls in packages from olpc-14 but also from
fedora (but I assume that is base not updates).

So my guess is this.  Our fc14 translate-toolkit relies of the fact that
aeidon is available in updates for F14.  But OLPC doesn't have those
updates either because it branched earlier or because it only uses the base
repo (not updates repo)

I'm also not sure why OLPC has not included the updates, maybe stability.

I'm wondering if there is a way to handle this in Fedora packages. I
already make package decisions depending on the Fedora version. I can make
the OLPC package even leaner if I know how to identify an OLPC branch.  If
you can help with that then I can probably build a new OLPC specific
package.


As for the issue with mesa I have a pretty good idea that it is not so much
an "error" with the pre-existing RPM as the fact that I think OLPC has
hacked a local copy down to size to save some space on the XO.  Choices
like that get made because of the extremely limited storage of the XO
laptop.  Let's call it a "misfeature" of a compromise that was made for the
right reasons. with unintended consequences.

So lets ignore it for this discussion.
