bug#15052: guix-0.3 make check fails, on gentoo-prefix setup

Hi,

I tried to make an ebuild for guix for the Gentoo meta-distribution.

I don't have a full Gentoo system at the moment, but an install known
as Gentoo Prefix [1], where you install packges in your home
directory, using the regular Gentoo tools (a bit like what guix does
on another distro).  So I wrote an ebuild for guix [2] atop of Gentoo
prefix (that sounds a weird setup as I write it).

So I run an uptodate Fedora 17, amd64, with a gentoo prefix in
~/gprefix.

The compilation goes fine. Except I don't get why guix-0.3 attempts to
download guile-2.0.7.tar.xz during compilation phase, while I do have
guile-2.0.9 installed.

However, make check fails:

I join the test-suite.log (compressed) and full build log (compressed
too).

I don't understand all failures, some are due to socket path length:

ERROR: In procedure connect:
ERROR: In procedure scm_to_sockaddr: unix address path too long: /home/cnicolas/gprefix/var/tmp/portage/sys-apps/guix-0.3/work/guix-0.3/test-tmp/var/7770/daemon-socket/socket

Hi!

Apff, yes, that’s a problem.  Guix clients connect to the build daemon
over a Unix-domain socket, and that has a shameful 108 character limit
on GNU/Linux.  Thus, all the test cases that try to connect to the build
daemon fail.

As a workaround, you could try to build in a shorter directory, if
that’s an option at all.

Alternately, you could try changing the ‘test-env’ script to use
relative directory names instead.

Can you try and report back?

TIA,
Ludo’.

Yes, I exported PORTAGE_TMPDIR=/tmp before running emerge, and all 19
tests went fine :-)

I haven't try it.  No real opinion on which one would be prefered.

Done!

Excellent!

BTW, if there’s a Gentoo package for Guix, you might want to send a note
on guix-devel.

Thanks,
