The “arm-linux-gnueabihf” is a cross-compilation triplet that we
generally support. However, note, Gérard, that not all packages in Guix
can be successfully cross-compiled, and Perl is one that fails to cross
build. We are not committed to supporting cross-compilation of every
package, but we’re of course happy to make the feature more useful.
The patch below is the beginning of a fix, but as it is, it builds a
native Perl. To address that, we need to fiddle with Perl’s peculiar
build system. If you know how to instruct it to cross-build, let’s
address this! :-)
Thanks,
Ludo’.
PS: This issue was previously reported at
<https://issues.guix.info/issue/27149> so I suggest we keep
discussing it there.
