Gentoo Forums

The new 17.0 profile is encouraged for arm. This involves a change in CHOST. In my particular case of a raspberry-pi this would change from

armv7a-hardfloat-linux-gnueabi

to

armv7a-unknown-linux-gnueabihf

I am supposed to use the script in
https://dev.gentoo.org/~chewi/armhf-migrate.bash

And I trust the Gentoo devs have done as always a fantastic job at checking many use cases.

I do have however a couple of questions.

1) I use distcc to crosscompile on this arm machine, will this script rebuild the system on my distcc server or natively on ARM?

2) What should I do on the distcc server? Should I install a new target for crossdev?

At first I was leaning towards not changing the profile, but the problem is that when those things get deprecated it's really hard to update.

potuz,

This script runs on the ARM system. It does nothing for the distcc helper(s).

You need to run there.

Moved to Gentoo on ARM, as it fits better there.

Code: Select all

crossdev -t <new_target>

there.

Thanks, would it help if I build the toolchain on the helper before running the script? would then the script rebuild some of the components using distcc?

potuz,

You can't use distcc with gcc and I've seen in make a mess of glibc too.

In theory, you can cross compile all the bits then install the binaries.
The script does a lot more than that though.
