How to install GCC 6.3 on trisquel 7

Here you go. If anything is not clear feel free to ask.

https://www.gnu.org/software/guix/manual/guix.html#Binary-Installation

Note for any code blocks the manual tends to use the standard $ for a normal user and # for a root user.

I have installed GCC5 using this PPA but i get the same error message:
requires at least GCC 5.0 (found 4.8.5)

Yes, it omitted that point.

Yes, for that step I had to use the Upstart commands instead. It seems on Trisquel 7 at least the init system is Upstart and not systemd. But if you attempting this on Flidas then I believe that systemd is the init that is used.


# ln -s ~root/.guix-profile/lib/upstart/system/guix-daemon.conf /etc/init/
# start guix-daemon


As for adding your user to the guix group that should have been handled by step 4 which linked to this page:

https://www.gnu.org/software/guix/manual/guix.html#Build-Environment-Setup

As I've explained I didn't encounter this error. If you run 'top' and search (CTL-L) for 'guix' do you see the guix-daemon running? If so then you've been successful in starting the daemon. Then I suggest you restart your machine and see if the daemon is running after booting up again by searching under top.

In which order did you attempt to make the series of `ln` commands?

It seems you made it in inverse order.

Also, if I'm not mistaken, Trisquel 7 doesn't use systemd entirely. It
does have Upstart instead (this is what I chose in the step that you
are right now).

This may also help resolve your issue.

haha, yes it does look that way. You should only need to install the glibc locales as your normal user. I did initially as root but then had to repeat it for my normal user account. In fact, I believe each unique user on the machine needs to install the glibc locales. So once the hello package under root installs check that it was successful by checking the list of installed packages with:

guix package -I

Then you can close that root terminal and use guix with your normal user account.

First and foremost, you must decide if you will authorize your copy of
Guix to trust the default build/substitutes/derivations service provider
(that is, the Guix project itself), the installation guide you followed
explains how to trust the default substitutes service provider (at step
7), it's important that you follow that section if you don't want your
own computer to try to build the universe.

Also, there are other package recipe and substitutes service providers
around the world of course, but these you have to find and add by
yourself. As you have seen, Guix is package manager which allows the
user to add custom packages, custom repositories, and custom
substitutes.

And, of course, after doing step 7, do the following as root:

# guix pull

Then you can proceed to do as the guide tells, for example:

This finishes the root-user-level installation.

However, as you said: `guix package -i hello` doesn't do what you
expect, this means *both* of the two things:

1. You're trying to run guix as normal user.

2. The `guix` command wasn't made available by the root user to the
other users, so you must have skipped step 6.

No, the daemon is a service that allows you to interact with the guix package store (/gnu/store). It is responsible for building packages on behalf of users and for downloading pre-built binaries from authorized sources. I don't believe guix notifies you of updates plus I don't see a need for it to do so. It follows a rolling release model where the available packages are built daily I believe. To get the latest updates of the packages you install you have to execute:

guix pull

Note, this will initially install guix itself! So, you use guix to update guix. How often you run guix pull is a question I posed to the mailing list and the response was that it is based on your feelings wrt security and stability.

Yes, as they work off different repositories and databases.

Add the following to your .(bash)rc file. This will add the guix pacakages to your path and make them available via the command line. So you should just be able to type avidemux3_qt5 for example or 'avi then TAB' would probably be enough to find it too.


export PATH="$HOME/.guix-profile/bin:$HOME/.guix-profile/sbin:${PATH}"
export GUIX_LOCPATH=$HOME/.guix-profile/lib/locale


You are getting the error


warning: failed to install locale: Invalid argument


most likely because you installed the locale for the root user and not your normal user and/or you did not define the GUIX_LOCPATH environment variable.

And if you want to add a menu item do so as in the attached screenshot. You can then add this to your desktop panel as well.

* Why somethings are missing?

Guix is managed *per-user* , so one must do most things per-user
depending on what must be done. Of course, somethings aren't needed,
e.g.: Installing graphical programs or icon themes for root user
(because root user doesn't really use these that much).

* Regarding missing icons

Install "adwaita-icon-theme" and "hicolor-icon-theme" from Guix, then
make a symbolic link to the resulting "Adwaita" and "hicolor"
directories (that are inside the user's Guix profile), like so:

(Note: remember to use `ln` with the `-s`/`--symbolic` option, and keep
paths relative so that things are easier to move around to other
computers or users, that is, remember to use the the triple "../" shown
here).

$ cd ".local/share/icons"
$ ln -s "../../../.guix-profile/share/icons/Adwaita"
$ ln -s "../../../.guix-profile/share/icons/hicolor"

* Missing application launchers in the menu

After installing an application, their .desktop files (application
launchers) are available in "$GUIX_PROFILE/share/applications".

For example, suppose I just installed GnuCash and Icecat for my current
user, then I do:

$ cd ".local/share/applications"
$ ln -s "../../../.guix-profile/share/applications/gnucash.desktop"
$ ln -s "../../../.guix-profile/share/applications/icecat.desktop"

Some applications still don't have the .desktop file, or it's not doing
all that it's supposed to do (e.g.: *Suppose* VLC doesn't appear in the
"Open with" right-mouse menu when clicking on some files, then this
might be an issue with the vlc.desktop file, or with your user's "mime"*
files in the same directory (".local/share/applications") or in
"/usr/share/applications", or in some other place people knowledgeable
of customization might have to englighten us. ;)

Can you post the output of (as your normal user)

guix package -I

So it seems you have installed the glibc-locales. You also have the smaller glibc-utf8-locales package as well so perhaps there is a conflict between the two. This seems unlikely though. Can you also double check you have set the GUIX-LOCPATH environment correctly? Otherwise, I'm at a loss so you may want to seek help on the help-guix mailing list.
