[gentoo-user] Gentoo on rpi

[gentoo-user] Gentoo on rpi

[Peter Humphrey]

Hello list,

I have a Pi 400, on which I'd like to install Gentoo if I can. I've tried a 
few approaches so far, but each one has fallen foul of some obstacle. For 
instance, today I tried installing a small Gentoo system into a chroot, to do 
the compiling there. It seemed to be going well until time came to upgrade 
openssl. It stopped when it couldn't cope with the ARM platform. Zlib also 
failed, needing static compilation, I think.

I see references to using crossdev, wine and taking a prebuilt system from 
various sources, but I haven't found a way through yet.

What setup do people use for compiling for Raspberry Pi? 

-- 
Regards,
Peter.

Use a standard Gentoo aarch64 (arm64 ) package. Add a pi kernel, the
/lib/modules directory and the /boot directory  from a raspian tarball.

I did this on a pi 3B running in 64bit mode. Once I had a bootable
system it was easy to modify and a fork from my first image is also
running on a couple of odroid 64bit systems (using the odroid boot and
kernel) and as an lxc image on a 64bit odroid n2.

Getting the /boot directory and uBoot config files sorted was the main
problem.

Use the equivalent from your local mirror.

Interesting...

I'll give that a shot. Thanks William.

I'm about to try this:

https://github.com/sakaki-/gentoo-on-rpi-64bit

for a couple of 3's and then some 4's when they turn up. Have you tried 
it and it fails?

Bear in mind apparently a normal pi boot setup doesn't work on the 400.
Don't know anything about it except apparently if you stick a card for
the pi 3 or 4 in a 400, it won't boot. It needs to be optimised for the 400.

Cheers,

Sorry, forgot about those thingies... Took the "400" to be a typo of 
"4", ie just the board....
