This is what ‘glib-or-gtk-build-system’ does. It would be worth trying
to change IceCat to use that build system.

Thanks for sharing. I can confirm that setting only XDG_DATA_DIRS works
in a container to solve the font issue. Setting XDG_DATA_HOME works as
well.
I don't need to set GIO_EXTRA_MODULES in order to get it to work (I
don't even have that directory on in my profile).

Only XDG_DATA_DIRS (or XDG_DATA_HOME) are needed for me in a
container. Is GIO_EXTRA_MODULES actually needed for anything? I don't
even have a `lib/gio' directory in my profile.

Yes, please. IceCat is effectively completely broken without this on
foreign distros and within containers. It looks like on GuixSD
XDG_DATA_DIRS is set in /etc/profile; I never had to set it manually.
But the presence in /etc/profile implies to me that there are other
packages that require this variable to be present. Should those
packages also have wrapper scripts?

I’m glad you figured this out. I wonder if this means that we should
change the icecat package to set these variables (e.g. by adding a shell
wrapper).
What do others think?

As it turns out that this might require changes to the icecat package,
maybe guix-devel is appropriate after all :) For other questions like
this, however, I’d suggest to ask on help-guix first. Either way,
thanks for bringing this to our attention.

Re: Missing fonts issue with GNU Icecat
Resolved by applying this advice (which is output when running
`guix package -i pango` explicitly, but not when pango is
installed as a dependency -- or I missed it):
```
The following environment variable definitions may be needed:
export
XDG_DATA_DIRS="$HOME/.guix-profile/share${XDG_DATA_DIRS:+:}$XDG_DATA_DIRS"
export
GIO_EXTRA_MODULES="$HOME/.guix-profile/lib/gio/modules${GIO_EXTRA_MODULES:+:}$GIO_EXTRA_MODULES"
```
(Besides, the web site gives other mailing lists (not in the info
manual)... maybe help-guix is better suited for this kind of
issues.)
Missing fonts issue with GNU Icecat
Hi guix, I have a profile with icecat, fontconfig and basic fonts, but the browser seems not to find any font. It displays only numbers-in-squares placeholders. ``` $ icecat (/gnu/store/x9c8vysvvivx4bc1xa4gz7sl37y3i2k6-icecat-60.3.0-gnu1/lib/icecat/.icecat-real:3240): Pango-WARNING **: 10:16:13.107: failed to create cairo scaled font, expect ugly output. the offending font is 'DejaVu Sans 9.9990234375' (/gnu/store/x9c8vysvvivx4bc1xa4gz7sl37y3i2k6-icecat-60.3.0-gnu1/lib/icecat/.icecat-real:3240): Pango-WARNING **: 10:16:13.107: font_face status is: file not found (/gnu/store/x9c8vysvvivx4bc1xa4gz7sl37y3i2k6-icecat-60.3.0-gnu1/lib/icecat/.icecat-real:3240): Pango-WARNING **: 10:16:13.108: scaled_font status is: file not found (/gnu/store/x9c8vysvvivx4bc1xa4gz7sl37y3i2k6-icecat-60.3.0-gnu1/lib/icecat/.icecat-real:3240): Pango-WARNING **: 10:16:13.108: shaping failure, expect ugly output. shape-engine='PangoFcShapeEngine', font='DejaVu Sans 9.9990234375', text='●' (/gnu/store/x9c8vysvvivx4bc1xa4gz7sl37y3i2k6-icecat-60.3.0-gnu1/lib/icecat/.icecat-real:3240): Pango-WARNING **: 10:16:13.113: failed to create cairo scaled font, expect ugly output. the offending font is 'DejaVu Sans 9.9990234375' (/gnu/store/x9c8vysvvivx4bc1xa4gz7sl37y3i2k6-icecat-60.3.0-gnu1/lib/icecat/.icecat-real:3240): Pango-WARNING **: 10:16:13.114: font_face status is: file not found (/gnu/store/x9c8vysvvivx4bc1xa4gz7sl37y3i2k6-icecat-60.3.0-gnu1/lib/icecat/.icecat-real:3240): Pango-WARNING **: 10:16:13.114: scaled_font status is: file not found (/gnu/store/x9c8vysvvivx4bc1xa4gz7sl37y3i2k6-icecat-60.3.0-gnu1/lib/icecat/.icecat-real:3240): Gtk-WARNING **: 10:16:14.576: Could not load a pixbuf from /org/gtk/libgtk/theme/Adwaita/assets/check-symbolic.svg.

How can I test if the issue is with pango or icecat or somewhere else? The "host" distro is Alpine. Best, --- Daniel Gerber
