One thing you could try is creating a traget filesystem with ptxdist.
So you would have at least an idea, which parts have to be put
together and have a look, if you can find the equivalents in the
portage-tree in gentoo. I guess that this should work. I tried ptxdist
for myself, but creating the target-fs did not work properly, nor did
the porting of Qt-embedded work correctly...
Yeah, that's the method I intend to use, so far, and I'm working towards
it right now, I think they've come a bit since you tried it, it seems to
work now, although it's got bugs aplenty still. It's the Gentoo parts
that I need help on, I don't even have a clue how to begin for those.
Not the Linix parts, in fact, I don't think I need even consider the
busy box (and to be honest, I'd rather not, they are SO messed up!)
BTW, use busybox if possible, to keep your target small. This allows
to use many commands with just one binary and some links.
Bye,
Andy
