Support for glibc 2.35

Support for glibc 2.35

[Olivier Dion via Development of GNU Guix and the GNU System distribution.]

Hello,

I would like to know if there's plan to add glibc@2.35 soon to the guix
channel?

I need it for a very specific feature in it and I would currently need
to roll my own version on my channel.  If it's planned to add it soon, I
would choose to postpone and wait for it.

Regards,
old

I'm afraid not. Bumping the version of glibc is not a trivial package
update in Guix, it means almost all packages need to rebuild (rebuild
the world).

If you really need it, you may inherit from a existing glibc package,
update to 2.35 and use it. But you may need extra patches to make it
work well.

I'd suggest you use docker and run some distro with glibc 2.35(FWIK Archlinux).

I see.  Well then I guess I will have to go that way then.

Can't do that.  I need guix for its reproductibility.

Right, so we update it in a separate branch, ‘core-updates’, together
with other “core” packages.  The branch gets merged roughly once every 6
months, so one needs to be patient (such updates take a non-negligible
amount of QA work!).

Yes, you can do that, use ‘make-gcc-toolchain’ (say) to build a custom
toolchain, and use ‘--with-c-toolchain’ to use that.

HTH!
