 Posted: Sun Nov 25, 2018 6:03 pm Post subject: new ARM profile and new CHOST |
 |
|
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 | Code: | | crossdev -t <new_target> |
there.
Moved to Gentoo on ARM, as it fits better 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.
