Hi,
i have an odroid-u2 with gentoo running on it here

i would like to change

Code:

-mfloat-abi=softfp

to hard

reinstalling with another stage3 is not an option

I know, that a binary and all linked libraries need to be build with same setting (soft,softfp XOR hard)
so it sounds to me, like I only need to re-bootstrap the system, that is :

rebuilding the tool-chain, and then try

Code:

emerge -e system

if a package fails, cause a depend-library still uses the old abi, i just will need to re-emerge this depended lib.

(1) Do you think that this will work?
(2) may be

Code:

/usr/portage/scripts/bootstrap.sh

is of any use?

1) Personally I'd redo the install from a stage3. 2) Yes, you can do stages 1 and 2 in a chroot using the bootstrap.sh (thanks to NeddySeagoon for insns.)
