Permissions error during libhandy build - looking for tips

Permissions error during libhandy build - looking for tips

Hi! I'm trying to package libhandy for Guix, but I'm running into some
issues. libhandy uses Meson for builds - I'm not super familiar
with it, but it looks like something during the installation process is
trying to write to a path in /gnu/store that it doesn't have
permissions to write to.

I'm still fairly new to Guix packaging so it's not obvious to me why
this is failing at the moment. I've attached the build log and what I
have so far for the package definition. If anyone has advice that could
be helpful here, it would be highly appreciated!

(This package also has tests that look like they require access to an
X server, which fail - I think this is expected? I've just disabled
tests for the time being, but is there any way to actually run tests
like that during a build in Guix?)

Hallo Jonathan,

I had a quick look at the log file and found this line:
PermissionError: [Errno 13] Permission denied:
'/gnu/store/m4jn72l561mppfh12br1vcrp9x9y812p-glade-3.22.1/lib/glade/modules/libglade-handy.so'

It tries to install the libglade-handy.so to the glade package, which is
forbidden. m4jn72l561mppfh12br1vcrp9x9y812p-glade-3.22.1 is a different
package, which you can't change during the install process of libhandy...

So there are two options from here:
- bring meson to install libglade-handy.so to the libhandy package
- don't intall libglade-handy.so at all

0.0.10 is out, I think we should package this version.

I would change this:
(origin
       (method url-fetch)
       (uri (string-append
"https://source.puri.sm/Librem5/libhandy/-/archive/"
                           version
                           "/libhandy-"
                           version
                           ".tar.gz"))

to an origin based on git-fetch from a tag. This is usually better in
terms of reproducibility:

(source (origin
              (method git-fetch)
              (uri (git-reference
                     (url "https://source.puri.sm/Librem5/libhandy")
                     (commit version)))
              (file-name (git-file-name name version))

I don't how to do this. For me it would be oke to disable the tests or
better to try to run those who doesn't require an X server.

By the way: Am I right in the assumption that you are interested in the
Librem 5?

Happy Hacking

Ahh, yeah, makes sense. I noticed that store path is different than
the one for the glade package in my profile, so I thought Guix might
have extended the glade package somehow... guess not.

Is the former the usual method for providing libraries like this? If
I'm interpreting this correctly, meson somehow found the path to the
glade package during the build, and I'd have to figure out how and
override that to ensure libglade-handy.so ends up in the build tree for
the libhandy package?

Assuming that's the case, am I correct in thinking that Glade (the UI
editor) will then be able to find libglade-handy.so because it'll be in
my profile?

You're right; I started attempting this before 0.0.10 came out, but
whenever I submit the package I'll pull in the latest version.

Ah, I forgot that the parameter to "commit" could also be a tag. I'll
adjust that.

Yup! I saw someone having trouble installing libhandy in one of their
chatrooms, and I was thinking it might be interesting to try and get
some of their software running with Guix. (Who knows, maybe we could
run Guix System on the Librem 5 once it's out!)

Usually in guix libraries also go in the same package and libglade-handy
gives the Glade "editor" libhandy "functionality". Sometimes we split up
packages in different "subpackages", but I don't think it's required
here. Libhandy will end up in the closure of GNOME sooner or later and
Glade is already in there (over libpeas -> totem).

Hmm, I'm not sure here, but you could try it :)

Fine :)

As I (also) per ordered a Librem 5, I dream as well from running Guix
system on it. Maybe I'll open a tracker bug to track all the things we
need to run Guix on Librem 5 :)

I just went ahead, feel free to add stuff there:
