Re: [eclipse-dev] Helios Ubuntu support plan

The Ubuntu 9.10 incompatibility with Galileo is XXXX and an Ubuntu
release of Galleo was released. Alas 3rd party plugins such as the
ontology editorTopBraidComposer (TBC) use the Galileo release and are
therefore unusable on Ubuntu 9.10, including the standalone
eclipse-based application.  That is because(?) the interaction is
between eclipse and GTK on Ubuntu.  Indeed, if one simply installs
Galileo from, it fails itself with the Ubuntu-fixed bug
(mouse events on buttons are not passed through to eclipse). I don't
know exactly what the Ubuntu Galileo did, but it doesn't ameliorate an
attempt to use the community edition of TBC---and probably the other
victims of the GTK/eclipse conflict.  Worst, in the case at least of
TBC, an attempt to install the plugin directly on an Ubuntu-released
Galileo fails with version conflicts.  I am not very familiar with the
eclipse plugin architecture, but the concern would be that a developer
cannot deploy a single plugin jar that runs on several flavors of
Linux, except possibly in source form.  Targetting Helios at Ubuntu
9.10 definitely will require addressing the GTK(?) conflict, because
it is easily exhibited entirely in Galileo and is so possibly at risk
for this in Helios too.

Because its support ends in September 2010, targeting  9.04 would not
likely meet your laudable goal of supporting enterprise distros.
