Hello,
I've a phone with replicant installed. It runs linux 3.0.x which is too
old for guix glibc (which requires linux 3.2.x). Using the hint at the
bottom of 'cross-base.scm', I successfully build cross-gcc with
cross-glibc 2.23 (configured with '--enable-kernel=3.0.0') for
armhf. Using them, I can cross-compile a statically linked hello world.
Is there an easy way to make relocatable guix pack with glibc 2.23
(configured with '--enable-kernel=3.0.0') for armhf? (My phone doesn't
connect to the internet, so I can't use 'guix pull' and 'guix
manifest'.) Right now, I have to manually set the '-B', '-I', '-L' and
'-sysroot' paths to cross-gcc to make it build hello world (which is
wrong and very tedious).
The snippet is copied below for reference, but please don't use it, it's
only a proof-of-concept. Thanks for help!
Cheers,
Alex

Hi,
I think I read somewhere (in the manual?) that you need a kernel 3.19 or greater to be able to use a relocatable guix pack. Since you're root on your phone though, you should be able to use a normal pack.
Maybe with inferiors you can use an older version of guix that works with your kernel?

I've checked the manual, it says:
Note: The ‘--container’ option requires Linux-libre 3.19 or newer.
I don't know how it's related to relocatable guix pack though.

I haven't tried inferiors before, will read the manual.
For the record, I find out that replicant maybe able to run the mainline
kernel in the future: <https://redmine.replicant.us/issues/1882>.
This should solve the 'FATAL: kernel too old' problem without me having
to cross-compile old glibc.
