guix can't find (gnutls)

Hi,

for some reason Guix can't find (gnutls) despite the module being
installed and usable in Guile:

Any suggestion?

Check that guix-daemon is also started with GUILE_LOAD_[COMPILED_]PATH
environment containing gnutls modules.

Are you running guixsd or runnign guix on a foreign distro?

I personally run guix on debian and had the same problem. I solved the
problem by building gnutls from source and installing it into
/usr/local. The problem is debian's gnutls doesn't contain
gnutls-guile.

One might suggests to install guix's gnutls and build guix using it, but
it doesnt't work for me, so I resort to building from source.

That's it!

I was test starting the daemon with "sudo guix-daemon
--build-users-group=guixbuild" from a shell with the GUILE_*
environment variables set correctly and things didn't work. Now I
defined those variables in the guix-daemon.system systemd unit and
things do work (I'm on Debian testing). I'm not sure of why the formed
didn't work, but the latter did it.

Thanks,
Fede

I had a similar experience: I installed gnutls manually in /usr/local
and successfully compiled Guix.

However, for various reasons, I then wanted to recompile Guix with
Guix (and remove the manually installed gnutls and Debian Guile) and
that's where I was struggling to make things work. I fixed things as
in my reply to Alex Kost.

Thanks for your reply.

I think that's because when you run "sudo guix-daemon" your environment
was not preserved; if you run "sudo -E guix-daemon", it would work.

I would try Alex Kost's method too, installing gnutls manually has the
disadvantage of needing to track security update manually. I adopt that
method only because I don't know a better one. Thanks Alex.
