Description Bodo Graumann 2017-12-21 06:48:41 UTC

media-sound/cantata uses fontawesome, as installed in /usr/share/cantata/fonts/fontawesome-4.3.0.ttf. Starting cantata though gives the following error:

Failed to compute left/right minimum bearings for "FontAwesome".

and fails to display most icons, as long as /usr/share/texmf-dist/fonts/type1/public/fontawesome/FontAwesome.pfb from dev-texlive/texlive-fontsextra also exists.

I somehow doubt that dev-tex*/* has anything to do with it.

Please check if you have media-fonts/fontawesome installed, and try to run cantata with /usr/share/cantata/fonts/fontawesome-4.3.0.ttf removed.

Comment 2 Bodo Graumann 2017-12-31 17:33:15 UTC

I do not have media-fonts/fontawesome installed and cantata has actually installed fontawesome-webfont.ttf, not 4.3.0.

Now, the following happens

with /usr/share/cantata/fonts/fontawesome-webfont.ttf
and /usr/share/texmf-dist/fonts/type1/public/fontawesome/FontAwesome.pfb:
In place of the icons only a narrow rectangle is drawn and I get the error
Failed to compute left/right minimum bearings for "FontAwesome".

without /usr/share/cantata/fonts/fontawesome-webfont.ttf
but with /usr/share/texmf-dist/fonts/type1/public/fontawesome/FontAwesome.pfb:
No icons are drawn, also no rectangle and no error message is given.

with /usr/share/cantata/fonts/fontawesome-webfont.ttf
but without /usr/share/texmf-dist/fonts/type1/public/fontawesome/FontAwesome.pfb:
The icons are drawn correctly and no error message is printed.

Comment 3 Eugene Shalygin 2018-06-13 14:36:06 UTC

Confirm the bug and the relation to /usr/share/texmf-dist/fonts/type1/public/fontawesome/FontAwesome.pfb. This little sample program [1] can be used instead of Cantata to verify the bug. However, I encountered this bug while trying to use FontAwesome icons in a zsh theme and discovered that Konsole displays no icons, while gnome-terminal does.
