Hi!
I'm using gentoo on freerunner and I'm quite happy with it. Actually I'm emerging natively to have access to a bigger number of applications than using cross-compilation and to help in ~arm keywording. To avoid taking the phone at home, emerging stuff and breaking the SD card with too many writes, I'm using a qemu-system-arm box building binary packages, and it's really slow (but faster the real device), for example qt 4.5.0 compiled in about 1 week. As of this I'm trying to avoid perodic "emerge -e", and reuse the stuff already emerged, so I need some tips to mantain a coerhent build system.
Last night I updated the openmoko overlay and noted that the xorg-server ebuild was updated, but when doing emerge -DuNpv world it did not appear in the list of rebuilding package. I think this is due the fact that the package did not changed the revision number. So is it possible to tell emerge to check that the ebuild was effectively changed for example checking the /var/db/pkg/* stuff? As alternative is there a ready to use script to do these cheks?
The second question is about dependencies as it may be that some packages in the last weeks loosed or gained some dependencies, or that them was autopicked from filesystem with autotools, to clean the system is the "emerge -e world && emerge --depclean && revdev-rebuild" the only solution?
May I suppose that cleaning /var/lib/portage/world from stuff, doing "ROOT=/stage4 emerge -gK world", chrooting to /stage4 and doing revdev-rebuild take me to the same results? May I produce a stage3 in the same way?
And last! do you know some fastand cheap arm based hardware I may use for arm native compilation? I'm interested in http://www.engadget.com/2009/02/24/marvells-sheevaplug-linux-pc-fits-in-its-power-adapter/ but I did not know if I may have issues using the openmoko toolchain on it.
Thanks
Nicola
