libcrypt.so.1 is no longer available from some distributions

Solution to issue cannot be found in the documentation.

[X] I checked the documentation.

Issue

When using perl from conda-forge on Arch Linux I see:

perl: error while loading shared libraries: libcrypt.so.1: cannot open shared object file: No such file or directory

To reproduce with docker (I'm using micromamba for convenience but I see the same with conda/mamba on a full desktop installation of Arch):

$ docker run -it --rm archlinux:latest bash
$ pacman -Syy && pacman --noconfirm -S wget && wget -qO- https://micromamba.snakepit.net/api/micromamba/linux-64/latest | tar -xvj bin/micromamba && bin/micromamba --root-prefix /micromamba-root create --name test -c conda-forge perl --yes
$ /micromamba-root/envs/test/bin/perl

Some more information:

libcrypt.so.1 in conda-forge's various sysroot_linux-* packages so we assume it's alwasy availble
glibc has deprecated this library and no longer build it by default
manylinux removed this from their whitelist a while ago (https://github.com/pypa/manylinux/issues/305)
Fedora has lots of helpful information here about using libxcrypt to provide libcrypt.so.1

I haven't done that much research but it seems like maybe we should be using libxcrypt instead.

@conda-forge/core Any thoughts?

isuruf commented 2 years ago

We can provide libcrypt.so.2 as part of libxcrypt package and use it in perl, python etc and then delete the headers and libcrypt.so.1 from the sysroot. This is what we did for libnsl.so.1 being removed from glibc.

(@chrisburr edited to change libcrypto.so.2 -> libcrypt.so.2)

That makes sense to me. I've opened a PR to staged-recipes for libxcrypt/libxcrypt-1: https://github.com/conda-forge/staged-recipes/pull/18377

After it's merged I'll look at making a repodata patch to make perl depend on libxcrypt-1 (and any other packages that depend on libcrypt.so.1).

For anyone looking for solution, you need to install libxcrypt1 package.

After it's merged I'll look at making a repodata patch to make perl depend on libxcrypt-1 (and any other packages that depend on libcrypt.so.1).

Maybe libxcrypt-1 get renamed to libxcrypt1?

Finally, done via gh-64.
