This perl-cross upgrade brings in a single new commit, by me, that
fixes the pkgsStatic.perl build.
Fixes: d1adf50277 ("perl: use pkgs.zlib instead of bundled zlib")
I don't understand how this worked prior to 1dbb306
("pkgsStatic.perl: Use `dontAddStaticConfigureFlags` instead of overriding"),
but what I do know is that it's very broken now, to the point that
perl-cross needs a patch.
I doubt the -Duseshrplib is actually necessary when native compiling,
but removing it would be a mass rebuild, so I've left it in place for
now.
This was originally in #105026, but then 5.30.1 happened with
this change included, so there were conflict and the patch
got dropped. Let's introduce it separately for only one version
that still needs it.
This adds a warning to the top of each “boot” package that reads:
Note: this package is used for bootstrapping fetchurl, and thus cannot
use fetchpatch! All mutable patches (generated by GitHub or cgit) that
are needed here should be included directly in Nixpkgs as files.
This makes it clear to maintainer that they may need to treat this
package a little differently than others. Importantly, we can’t use
fetchpatch here due to using <nix/fetchurl.nix>. To avoid having stale
hashes, we need to include patches that are subject to changing
overtime (for instance, gitweb’s patches contain a version number at
the bottom).
Perl on darwin (and any other sane platform) has a pretty good threading
support, enable it.
As it turns out, we were building non-multithreaded perl on all systems,
since glibc was not part of the stdenv anymore:
nix-repl> pkgs = import <nixpkgs> {}
nix-repl> pkgs.stdenv ? glibc
false
meaning that the comments were incorrect. Thus, clear up the confusion
and remove the misleading comments, while enabling multithreading by
default. The builds will fail on unsupported platforms, and in this case
the only place is the bootstrap, where we already force
non-multithreaded perl.
As a consequence of the above, this change will cause the full rebuild
of stdenv on all platforms, including linux.
In "perl: fuse configureFlags" [1] the effects of the preConfigure
phase were merged into configureFlags. After this change values with
spaces do not reach the configure script intact.
The only flag this affects is `ldflags` for Aarch32 and Mips, and perl
builds without it on armv7l-linux so it's probably no longer required
on any platform.
