Re: Core-updates: Downloads do not work

Hi Andreas!

Ah, you need to:

  $ rm distro/packages/bootstrap/x86_64-linux/guile-*.tar.xz
  $ make

The latter will download the current guile-2.0.7.tar.xz bootstrap
binary, and check its hash (the hash of that tarball is only checked
upon downloading, by build-aux/download.scm.)

That’s because guix-download uses your Guile, which is a full-fledged
Guile linked against a feature-complete libc, whereas the old bootstrap
Guile was statically linked against a libc whose getaddrinfo depended on
a running nscd to work.

Does that clarify a bit?  :-)

Thanks,
Ludo’.
