Installation binaire de Guix sur Debian

• Objet : installer le package manager Guix sur Debian
• Niveau requis :

  débutant, avisé
• Commentaires : https://git.savannah.gnu.org/cgit/guix.git/plain/etc/guix-install.sh
• Débutant, à savoir : Utiliser GNU/Linux en ligne de commande, tout commence là !.

Il s'agit de récupérer un script shell d'installation, de le rendre exécutable et de le lancer. Celà installera Guix aux côtés des autres gestionnaires de paquetage sans les altérer de quelque façon que ce soit.

J'ai copié-collé le script dans un nouveau fichier à l'aide de vim, vous pouvez le copier-coller d'ici si vous avez la flemme de le télécharger :

Voilà, il ne reste plus qu'à commencer à explorer ce nouveau package manager installable sur toute distribution GNU/Linux.

# apt install info

# info guix

Pour vérifier que Guix a bien été installé, j'ai lancé :

# guix install hello
..................................................................................
Guix a installé les paquets nécessaires aux dépendances : guile-2.2.4, 
texinfo-6.5, pkg-config-0.29.2, perl-5.28.0,  module-import-compiled, 
mkfontdir-1.0.7, module-import, mkfontscale-1.2.1, libunistring-0.9.10, 
freetype-2.9.1, libpng-1.6.37, libpng-1.6.34, libltdl-2.4.6, libgc-7.6.6, 
libfontenc-1.1.4, coreutils-8.30, libffi-3.2.1, libcap-2.25, libatomic-ops-7.6.6,

1 paquet dans le profile
Il pourrait être nécessaire de définir les variables d'environnement suivantes :
 
export PATH="/root/.guix-profile/bin${PATH:+:}$PATH"

root@debian:~# export PATH="/root/.guix-profile/bin${PATH:+:}$PATH"

Test d'installation d'un logiciel depuis le compte user :

$ guix install quassel

Installation d'un nombre considérable de dépendances, 406,0 Mo seront téléchargés

1 paquet dans le profile
Il pourrait être nécessaire de définir les variables d'environnement suivantes :
   export PATH="/home/hubert/.guix-profile/bin${PATH:+:}$PATH"

hubert@debian:~$ export PATH="/home/hubert/.guix-profile/bin${PATH:+:}$PATH"

hubert@debian:~$ quassel

quassel se lance sans problème

Tout a l'air de bien se passer pour l'instant, je prévois des mises à jour de cette page au fil des avancées…

Hum hum…

hubert@debian:~$ quassel
 
Command 'quassel' not found, but can be installed with:
 
apt install quassel
Please ask your administrator.

Bon alors là ?…

Un petit tour sur l'irc #guix m'apprend qu'il faut que je rajoute dans le ~/.bashrc du compte user la ligne suivante :

nom.sh

export PATH=$PATH:$HOME/.guix-profile/bin

Et ça y est, maintenant quassel se lance sans probème. Il m'a suffi, avec gedit, de copier-coller la ligne tout-en-haut du fichier et de l'enregistrer. Le problème qu'il y avait, c'était que la modification apportée initialement ne concernait que le ~/.bashrc du compte root.
