[Message part 1 (text/plain, inline)]

Broken:

$ guix shell --pure inkscape -- inkscape

(crashes on start with ‘Inkscape encountered an internal error and will
close now’.)

Work-around:

$ guix shell --pure inkscape gdk-pixbuf -- inkscape

also works:

$ guix shell --pure inkscape gdk-pixbuf -- /usr/bin/env GDK_PIXBUF_MODULE_FILE=/gnu/store/[...]-profile/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache inkscape

Looks like some wrapping is required to point GDK_PIXBUF_MODULE_FILE to an appropriate 'loaders.cache'.

Also starts in a non-pure environment without adding extra packages, but then the icons aren't found.

Greetings,
Maxime.

I'm surprised gdk-pixbuf is enough; I would have expected you need to
add adwaita-icon-theme and librsvg (for the SVG pixbuf loader).  I guess
it has all the icons already but doesn't have even a non-svg loader.

The annoying part with GDK_PIXBUF_MODULE_FILE is that if we wrap it, it
can't be extended by the user given the variable takes a single value;
so suppose we wrap it without librsvg, then Inkscape will loose the
ability to load the SVG version of its icon, which probably look better
on high resolution displays.

Currently, I think we also cannot add librsvg to inkscape inputs, as it
would introduce a cycle; we'd have to come up with a new minimal variant
used by dblatex.

I guess we could have a minimal and a full-blown version of Inkscape,
the later which would include librsvg and wrap GDK_PIXBUF_MODULE_FILE.

Thanks,

Maxim

I've now implemented this, upgrading Inkscape to 1.2 in the process.
See commits 023259c4bd1a38225fb1c06660c0cf393210e811,
7dcba233a3745cfdcc291adf46261548eb2f3d76 and
b1523ffac597d56ab9657ab1c1b1a7fc49344d67.

It's now possible to 'guix shell --pure inkscape -- inkscape'!

Thanks for the report.

Closing.

Maxim

I can confirm it works!

Thanks,
