changing -mfloat-abi on arm

[Treborius]

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

i would like to change

Code: Select all

-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: Select all

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: Select all

 
/usr/portage/scripts/bootstrap.sh

is of any use?

1) Personally I'd redo the install from a stage3.

2) Yes, you can do [post=7725780]stages 1 and 2 in a chroot[/post] using the bootstrap.sh (thanks to NeddySeagoon for insns.)
