installing python 2 and python 3 in the same profile

[Ricardo Wurmus]

Hi Guix,

with the introduction of the collision avoidance feature that prevents
you from installing different variants of the same package into a
profile we made it impossible to install “python” and “python@2” into
the same profile.

It still works with ad-hoc environments, but manifests containing both
Python versions cannot be instantiated any more.  This is too strict,
because we know that these two variants don’t cause conflicts.

What can we do to make this feature a little smarter?

How about a package property that defines a “conflicts?” predicate that
takes two packages of the same name and determines (e.g. by checking the
major version) if these two packages are conflicting?  If no such
predicate is provided we assume that packages with the same name cause a
conflict and prevent installation.

[PATCH] fix idris (was "Re: Incomplete work to upgrade Idris to 1.2.0")

[Alex ter Weele]

On guix-devel¹, I had given an incomplete patch to update idris to
1.2.0. After further investigation, I concluded this was the wrong
approach because our current version of GHC is 8.0.2, so the right
version of LTS Haskell to follow is https://www.stackage.org/lts-9.4,
which includes Idris 1.0, not 1.2.

Big thank you to sclv on #hackage for all their help.

These are good points.

I should clarify that I suggested to Reshu to use the script to get
started a little more quickly.  This is for making a first recorded

This sound complicated for the occasional (staging-) contributor.

How should I determine when the next round is about to start? I can't
even spot that "staging is nearly fully built" and hydra's web-front-end
is slow. Further I do not have the time for monitoring hydra and catch
the time-window then I can push my commit. For me this does not work out
- and I assume for others if doesn't, too.

Is there some queue-for-staging branch where I can commit this patch to?
Or some other means, like setting some bug-status?

Creating and/or editing a script should not be necessary; 
guix-install.sh is part of Guix, and you should be able to simply run 
‘sudo bash ./etc/guix-install.sh’ from your Guix tree.

You need to run the script as the root user.  It seems to not like to
run with sudo, so you would need to do “sudo su -” first to switch to
the root account.

(I’m not sure if the root account is usable on Ubuntu.)

If the script doesn’t work for you, I’m afraid you’d have to follow the
installation steps manually.  As Konrad explained, the procedure is

Finally some practical advice: once you have guix, you can build guix from
source in a "guix environment guix".
You can edit a package receipt with "guix edit pkgname", and search the
packages with "guix package -s pkgname".

You can install guix on a foreign distro, so you don't need to set up
GuixSD if you want to work on guix. However, if
you would like, then you are welcome to do so. We also provide a virtual
machine image with GuixSD, but my last
experience with that it needs resizing to do anything useful (not enough
disk space there).

This section will be very useful if you like to learn by examples:
https://www.gnu.org/software/guix/manual/html_node/Defining-Packages.html#Defining-Packages
.
You can easily expand from there, and looking at package receipes
containing similar to software to the one you are willing to package.

You can have a look at:
https://debbugs.gnu.org/cgi/pkgreport.cgi?package=guix, the guix bug
tracker, and
https://debbugs.gnu.org/cgi/pkgreport.cgi?package=guix-patches, this is for
tracking patches. New packages, and updates get listed here after mailing
to guix-patches.

You can find contact information on our home-page:

Yeah, this was also quite a surprise to me.

David, would it be wrong for us to change the behaviour such that only
direct inputs end up in the environment?

Aside from this issue, I find it worrying that the graft for glibc does
not end up in the environment.  This is a serious problem for those
who use “guix environment” on RHEL 6.

Ludo, do you know if this is a more general bug or if it is due to the
design of “guix environment”?

Staging is nearly fully built, so it will have to wait until next round.

Generally, branches 'close' once a Hydra evaluation starts.  Check in
here for progress: .

Currently evolution-data-server fails to build, I've sent some patches
here: .  Once that is fixed, we'll do a new
(hopefully last) evaluation and merge if there is no fallout.

PS: GNOME users, please test staging when #30733 is merged, since it
updates evolution-data-server to 3.26 while most of GNOME is still
3.24.

Hi Ludo,

How can it be that (gnu services base) with find-long-options call is present
but the (gnu build linux-boot)'s find-long options isn't present?

Aren't they either both added by "guix system reconfigure" (or both removed)?

Also when selecting an old generation in the Grub boot menu, isn't both
(gnu build linux-boot) and (gnu services base) at the same generation when
starting up the service (as opposed to stopping the old service)?

Yes please.

The idea was that if you specify a serial console at boot that you can
actually log in at that console.

So it's trying to find out whether, at the time of service start,
there is a serial console specified (in the Linux command line), and if
so, start an agetty.  Otherwise do not start that agetty.

We could also do that without a guix service - but I thought it would be
nice to have a guix service for it as well.

I agree. In written Chinese, the 2 dialects of simplified and
traditional Chinese are quite different. Not only the characters are
different (of course quite a few are still shared), sometimes the
wording is different too due to cultural difference (similar to British
vs American English). So we should at least have 2 different locales I
think.

I would also like to follow W3C if possible. However, I am not sure how
well it is supported by browsers? Is there some way to test it?

Also, I see that guix has simplified Chinese translated in
'guix/po/guix'. Are we required to use the same locale in guix and in
the web page?

I also want to add tranditional Chinese translation to guix in the
future (after I figure out how to use handwriting recognition). I think
I will still use the zh_TW since I think it is an established convention
for distro. But I am not sure if the same convention holds for web
page.
