Actually, when cross-compiling, the phase procedures are passed #:inputs
and #:native-inputs. So “libc” is in the #:native-inputs alist, while
“cross-libc” is in the #:inputs alist.
So you’d have to do something like that:
(assoc-ref inputs ,(if (%current-target-system) "cross-libc" "libc"))
This is not great, and we should probably fix that in the next
‘core-updates’. In the meantime, that’s what we have.
The packages needed to cross-build ‘bootstrap-tarballs’ (as Hydra does)
either do not refer explicitly to libc, or have a special case that
removes the need to refer to it (as for ncurses), which is why we never
came across that before.
Thanks,
Ludo’.
