Installing guix on nixos system

Installing guix on nixos system

[Roy Lemmon]

Hi,

I am trying to install guix on my nixos system. I am using the shell script
provided on the guix installation page:

https://git.savannah.gnu.org/cgit/guix.git/plain/etc/guix-install.sh

All works well until the script tries to install the guix-daemon service.
It cannot install it in /etc/systemd/system and so the daemon cannot be
started. See below.

Has anyone come across this problem ? I thought /etc filesystem was
writeable as that is where configuration.nix lives.

Thanks
Roy.

Thank you. I will take a look at that link. It does indeed look helpful.

Re: Installing guix on nixos system

[Roy Lemmon]

Hi All,

I have followed the instructions in that link and successfully installed
the build users and guix daemon on my nixos system. As root, I can run

guix package -i hello

and the hello package is installed and I can run it.

However I am having trouble setting up the environment for running guix as
a user (I am on my laptop, so there is only one user). guix is of course
not recognised as a command when I am the user. I can run it as
/usr/local/bin/guix so that is ok and I could put that in my PATH. But is
that all I need to do ? I am not sure where the guix packages are installed
as a user rather than root.

Thanks
Roy.

I haven't read the linked blog post, but I think the next step is to use
the Guix in /usr/local/bin to run 'guix pull' as your user.  That will
install the latest version of Guix in ~/.config/guix/current.

Afterwards, make sure ~/.config/guix/current/bin comes first in PATH,
then you should be able to use Guix normally.

Re: Installing guix on nixos system

[Roy Lemmon]

Hi Marius et al.,

Thanks for your help. That is clearer now. In fact that is what I did, ran
'guix pull' as user and the latest version of guix is installed in
~/.config/guix/current.

My problem now is that I can run guix from there if I use the full path
name:

$ ~/.config/guix/current/bin/guix --help

But if I just run:

$ guix --help

it doesn't recognise the command. Normally this would just be because I
have not added that directory to PATH as you say.

However here is the problem. I am using eshell in emacs. I have tried the
following:

$ (setenv "PATH" (concat "/home/rlemmon/.config/guix/current/bin:" (getenv
"PATH")))
$ addpath /home/rlemmon/.config/guix/current/bin

But still the same problem. I understand this is now an eshell problem
rather than a guix one. But if anyone has encountered this before ... ? Its
a frustrating problem !

Thanks
Roy.

Just tested this with Emacs 26.3, it works for me.

What's the result of the following commands in Eshell?

which guix
*which guix

Anyways, you should probably set the PATH environment during login,
e.g. in your ~/.bash_profile or ~/.profile.  This way the correct
environment variables will get automatically propagated to all your
applications.

Cheers!

Did you try installing the guix-daemon.service file by hand? Did you
check the permissions of '/etc', and '/etc/systemd', etc?

Did you try putting the guix-daemon.service in root's systemd service
directory, '/root/.config/systemd'?
