[Andreas Enge]

Hello,

thanks to Ludovic's help, who noticed that the pango input harfbuzz should 
be propagated, and after disabling the X server related tests, I managed to 
compile gtk+. I just pushed the new package, but so far, I did not test it 
with any application, so it might not even work...

Neat, in time for 0.3, thank you!  :-)

I just added it to Emacs:

... and it actually built directly.  :-)

Now, the widgets that use Pango for font rendering (I suppose), like
menus, display squares instead of actual characters, and the console is
filled with things like:

Fontconfig error: line 139: invalid attribute 'xml:space'

I guess we’ll need a pseudo-package that creates a fonts.conf file for a
given set of fonts, like
<https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/fontconfig/make-fonts-conf.nix>.

Amusingly, emacs works for me:

Fontconfig warning: "/nix/store/7215jba0vzhizmgj0kmljmhl86wy28va-
fontconfig-2.10.91/etc/fonts/conf.d/50-user.conf", line 14: reading 
configurations from ~/.fonts.conf is deprecated.

since it uses ~/.fonts.conf from my debian system!

Definitely, we need to discuss how to handle font installation.

I still get these.  However, once gs-fonts is installed in the profile,
everything displays correctly (thanks to commit
0ceea4f3edb6fd158613f2c46d18e037bc183f1a).

My .emacs does this:

  (set-frame-font "Bitstream Vera Sans Mono-12" nil)

So I packaged that font.  Once it’s installed, it’s loaded and used as
expected, and everything works beautifully!

We should probably add a section “Installing and Using Fonts” under “GNU
Distribution”, to explain that fonts are searched for in the user’s
default profile.  Any volunteer?  :-)

Thanks,
Ludo’.
