[gentoo-embedded] bootstrapping uclibc

[gentoo-embedded] bootstrapping uclibc

[Douglas Campos]

In the old days, we started with a static toolchain to build the uclibc 
(a la buildroot), then re-bootstraps everything with the new uclibc as libc

I ask: in the case of uclibc-0.9.28 (aka 2006.0) what will be done? 
google doesn't helped a lot.
I know that uclibc-0.9.28 breaks binary compatibility.
How to do the major update in a gentoo-way?
catalyst breaks, /usr/portage/scripts/bootstrap.sh breaks, emerge -e 
system breaks....

If anyone can help, I will be grateful

emerge 0.9.28 with USE=uclibc-compat and it should be binary compat
with 0.9.27 ... then just re-emerge all your packages and you can
drop the uclibc-compat from USE and rebuild 0.9.28

I am also interested in this.

I am also wondering if anyone have an idea about how long time it will
take before the uclibc-0.9.28 gets marked as stable.

We will probably start moving a libc based system over to uclibc in
january. I hope to use gentoo as a base for this, but I would prefer to
wait til 0.9.28 get stable to avoid another bigger update.

The emerge fails on hardened.

You are doing a great work, Mike.

Is there anything I can do to help?

Yes. get yourself up to par and join the team.


Here is a set of intermediate ~arch packages for the CHOST you were 
using which can provide a stageXX or allow you to revocer from a 
previous screwup.

ftp://tinderbox.x86.dev.gentoo.org/i386-gentoo-linux-uclibc/

CFLAGS="-Os -pipe -DSUSPICIOUS_BUF_SIZE=2"
CHOST="i386-gentoo-linux-uclibc"
CXXFLAGS="-Os -pipe"
USE_ORDER=env:pkg:conf:defaults
ACCEPT_KEYWORDS="x86 ~x86"
FEATURES="confcache buildpkg"
MAKEOPTS=-j4
USE="hardened pic"
PATCH_OVERLAY=/usr/portage/local/patches/
PKGDIR="/usr/portage/packages"
PKGDIR=$PKGDIR/$CHOST
