1 The context
=
Suppose there's an open directory publicly available on the
Internet. I want to define a Guix package that downloads multiple
files from that directory.
2 What I know
=
I know how to define a package that downloads a single file.
Let's consider [this] directory for our experimentation (I chose it
because it has relatively small files). Suppose I want to download the
file `blindtext.dtx' and make it available in
`~/.guix-profile/share'. My package definition would look as it
follows.
,
| cat ~/my/git-repos/guix-packages/my/test.scm
`
,
| (define-module (my test)
| #:use-module (guix licenses)
| #:use-module (guix packages)
| #:use-module (guix download)
| #:use-module (guix build-system copy))
|
| (define-public my-package-1
| (package
|(name "my-package-1")
|(version "1.0")
|(home-page "My home-page")
|(synopsis "My synopsis")
|(description "My description")
|(license gpl3+)
|(source
| (origin
| (method url-fetch)
| (uri
"http://tug.ctan.org/tex-archive/macros/latex/contrib/blindtext/blindtext.dtx;)
| (sha256
| (base32
|"10sfm4648v1ywki639jsl5darkcil1is462w0v65xxr75k4l1ywl"
|(build-system copy-build-system)
|(arguments
| '(#:install-plan
| '(("blindtext.dtx" "share/"))
`
I would install that package with the following command.
,
| guix package --no-substitutes -L ~/my/git-repos/guix-packages -i
my-package-1
`
,
| The following package will be installed:
|my-package-1 1.0
|
| hint: Consider setting the necessary environment variables by running:
|
| GUIX_PROFILE="/home/rdrg/.guix-profile"
| . "$GUIX_PROFILE/etc/profile"
|
| Alternately, see `guix package --search-paths -p
| "/home/rdrg/.guix-profile"'.
|
`
The file gets created in the following path which is symlinked to the
following file in `/gnu/store'.
,
| realpath ~/.guix-profile/share/blindtext.dtx
`
,
|
/gnu/store/mmqc8wav2jj3m3harisvawl1r881glpv-my-package-1-1.0/share/blindtext.dtx
`
[this] which mentions
`simple-texlive-package')
In other words, consider that the directory we are using for our
experimentation is an arbitrary directory on the Internet and that
there's no way of downloading the compressed version of that
directory. I'm poing this out because I'm more interessted in learning
how to define a package that downlaods multiple files instead of
finding a workaround that installs `blindtext'.
Re: Identifying cause of local package build
Hi, I would also check the size of /tmp partition. I build of iced-tea / openjdk was failing because it was running out of disk on /tmp. guix-daemon builds packages in /tmp . Some packages need a lot of disk to build. In my case I had to increase /tmp to 7.5 GB until the build passed. This was visible in the error log and the same issues was happening on substitute servers (build was failing with this issue).

Hi all, Maxim Cournoyer writes: > For moving Guix itself, you could copy its root file system > using 'cp -a', or opt to reinstall from your config.scm as already > mentioned up-thread. I strongly suggest the reinstall option. Copying all with “cp -a” works, but is a waste. sudo mount /dev/sdx1 /mnt sudo cp -a /etc/config.scm /mnt/ sudo cp -a /home /mnt/ sync is a simple means of backup. Reinstall can be done with sudo mount /dev/sdx1 /mnt sudo cp -a /mnt/etc/config.scm /etc/config.scm sudo cp -a /mnt/home / Then adjust the file-systems field in /etc/config.scm and reconfigure. > Sadly, for the complex part (the bootloader > configuration), I'll leave it to someone more knowledgeable than myself > to provide concrete answers, but I believe you'll want to read on > something called multi-boot. There's a GRUB example here [0]. I believe configuring GRUB for dual boot is difficult. It would be simpler if the computer already offers boot selection e.g. when pressing the DEL key at startup. That would allow choosing between multiple EFI installations. I think GRUB multi-boot is a boot protocol that cannot easily be configured in Guix. Other distros use GRUB menu-entries with chainload for dual booting. Regards, Florian
Re: Error when tab-completing Guix-subcommand in Emacs' Eshell
2023-05-25 09:03 mek...@posteo.de:
Hello Guix! :)
Hello Mekeor!
When I open Emacs ("emacs -q"), run Eshell (M-x eshell RET) and
type "guix " followed by TAB, why do I get the following error
message?
This happens because Eshell does not run the external program
"guix" but the emacs-lisp function "guix" from the emacs-guix
package that is broken, as far as I know. As described at (info
"(eshell) Built-ins"), you can try typing "*guix" instead. (Or
uninstall emacs-guix.)
I hope that helps!
