[gentoo-user] Error with infinality font while emerging sane-backends

[gentoo-user] Error with infinality font while emerging sane-backends

[Danny YUE]

Hi folks,

I am trying to emerge xsane, which requires sane-backends.
However, the sane-backends package fails forever with error message like
below:
--- BEGIN ---
Fontconfig error: Cannot load config file "infinality/conf.d"
Error: /invalidfont in /findfont
--- END ---

I have only "52-infinality.conf" enabled in "eselect fontconfig".
I suppose this is a problem related to infinality fontconfig I am using.
But how am I supposed to fix this?
I googled a lot but no result. :-(

The full build log is here: https://pastebin.com/8fjnqmHw
emerge --info: https://pastebin.com/aharCut1

Thanks in advance for any potential help. :-)

Danny

That is probably because media-libs/fontconfig seems not to canonicalise 
relative target path for symlinks.

As a quick, but volatile, solution you can re-create symlink:

    ln -s /etc/fonts/infinality/styles.conf.avail/linux \
          /etc/fonts/infinality/conf.d

or you have to patch the module:

    /usr/share/eselect/modules/infinality.eselect

of app-eselect/eselect-infinality-1 to use full qualified paths.

Test configuration loading afterwards, e.g. with `fc-match monospace`.

Thanks for your quick reply :-)

I created the symbolic link as you told, but it still does not
work...same error message.

That solves the:

	Fontconfig error: failed reading config file
	Fontconfig error: Cannot load config file "infinality/conf.d"

errors – they’re gone.

>but it still does not

Now you have to solve the:

	Error: /invalidfont in /findfont

	Last OS error: No such file or directory
	GPL Ghostscript 9.21: Error: /invalidfont in /findfont

errors. The culprit seems here the Type-1 font selection, see bug 
#620148 [1]. Commenting the mentioned section in:

    /etc/fonts/infinality/infinality.conf

works here, bumping Ghostscript to version 9.23 doesn’t.

Hope that helps. If not, you probably can temporarily rename:

    /usr/bin/fig2dev (package media-gfx/transfig)

to hide it from the media-gfx/sane-backends build process, so it wont 
build the PDF documentation. Previously sane-backends-1.0.27 compiles 
fine without media-gfx/xfig and therefore media-gfx/transfig.

Oops, I did not really see this email last week...my stupidity.

Thank you so much Floyd, you solved my problem perfectly.

After commenting out the section, the font problem never appeared any
more.

However the PDF file still refuses to build.
I knew the solution: disable parallel compilation feature.

After that it worked.

Thanks again!

Danny
