cannot load fonts

cannot load fonts

[Luca Ferrari]

Hi all,
I've compiled Emacs 28.1 without any particular option on Ubuntu
20.04. Then I've placed the following in my startup file:

(set-frame-font "Source Code Pro")
(set-face-attribute 'default nil :font "Source Code Pro" :height 140)
(set-face-font 'default "Source Code Pro")


However, when Emacs starts, it prints me a warning message and the
font is not loaded:

Warning (initialization): An error occurred while loading
‘/home/luca/.emacs.d/init.el’:
error: Font not available, #<font-spec nil nil Source Code Pro nil nil
nil nil nil nil nil nil nil ((:name . Source Code Pro) (:user-spec .
Source Code Pro))>

but the fonts are there:

What am I missing here?

Thanks,

I found there is a much more annoying problem that I cannot fix: if I
select the menu 'Set Default Font', the font menu has only three items
with "misc", "courier" and "fontset". This prevents me to select any
decent font in the system, and I don't know how to fix it.
I've tried to load emacs with, in turn, --no-x-resources,
--no-init-file, --no-site-file but nothing changes.
I don't have any font settings in XResoucres:

% xrdb -query
*customization: -color
Xcursor.size:   36
Xcursor.theme:  breeze_cursors
Xft.antialias:  1
Xft.hinting:    1
Xft.hintstyle:  hintslight
Xft.rgba:       rgb

I've tied to recompile emacs with --with-x-toolkit=yes or
--with-x-toolkit=gtk3 but nothing changes.
If I install ubuntu stock emacs (26!) it works as expected and gives
me a full list of fonts.
Anybody has a clue to fix the problem with my emacs 28?

Thanks,
Luca

Show us your `system-configuration-features' and `(frame-parameter nil
'font-backend)'

I suspect you donʼt have the development packages installed for
various font-related libraries.

That's the fallback font menu displayed if there is no "native" toolkit
font dialog (i.e. the GTK one, when Emacs is built with GTK).  This
problem with the fallback menu has also been fixed in Emacs 29.

Do you have the GTK 3 development files installed?

Great!
Installng libgtk-3-dev and recompiling (not sure it was required) it now works.

Thanks,
