This makes it sound like a separate implementation of Perl. But it's only a configure script + Makefiles to be used with standard Perl.
How about this, taken from the their github page: "Configure and build perl with a cross-compiling toolchain".

Is it too bold to make the perl-cross build system overlay the default build environment for native too? (In any case, it can wait, I'm just curious.)

I like the idea of merging them, and just pushed fixes that get this working by (among other minor fixes) grabbing most of the existing expression.
I don't think using it by default will go over well-- I thought this came up before but can't find the discussion now...
Of course it would be convenient if we could use the same for both!

Good catch!
After investigating, the answer is actually "no"--it's just that the original hash from the earlier commit
was from 5.22.4 not 5.22.2. This hash matches the one we're using for this version in the 'normal' perl expression.

(and I just refetched and confirmed, for some reason the download went realllyyyy slow)

Tested that native hash doesn't change, and still builds successfully for cross on raspberryPi and aarch64. EDIT: squashed! cc @Ericson2314 |
