[gentoo-embedded] basic question

[Geoff O'Callaghan]

Hi Guys,

Sorry for such a basic question.   I'm used to openembedded style builds
which you could say are 'almost' like the gentoo approach to source
level builds.    I must confess to never having used Gentoo (sorry about
that ;-)  ) though I like the concept.   And now for the question.

For a given build (eg cross compile -> ARM flash based system) is the
Gentoo-embedded methodology to build a flashable image which i'm
expected to flash OR is there a mechanism for creating something like an
ipkg that I can install on my existing target - having both options
gives me a lot of flexibility.   So what's the approach for embedded
gentoo?

I'm not aware of any tool in gentoo right now that x-compiles and then 
makes the flash image. Mostly we all merge into an alt ${ROOT} and then 
go run genext2fs/mksqushfs/mkfs.jffs2 or whatever suits your needs for 
the type of flashable image you are creating.
The gnap project does do building, merging and dumps out a flashable
image when it's all done. But afaik gnap is mostly targeted at native
compiles vs x-compiles.

The qmerge util from portage-utils is an ipkg/apt* work alike.

Provide the tools & development environment for users and let them 
figure out what's best for the device they own.
