fontconfig 2.3.2_1+macosx slows down GraphViz

[sf@…]

Graphviz currently gives an error: Error: fontconfig: Didn't find expected font family. Perhaps URW Type 1 fonts need installing? : Times-Roman

I tried to see if an upgrade of fontconfig would solve the issue, but it does not. In fact, it only makes the problem worse, because now it takes way more cpu cycles to generate a graph with a non-default font:

Graphviz currently gives an error: Error: fontconfig: Didn't find expected font family. Perhaps URW Type 1 fonts need installing? : Times-Roman

It seems that you haven't installed URW Type 1 fonts though graphviz needs that fonts. Here is a way to install 'urw-font' port. I hope this will help you.

1) create your own 'loclal.conf' file.

$ sudo emacs /opt/local/etc/fonts/local.conf

opt/local/etc/fonts/local.conf------- <?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig>

<dir>/usr/local/share/fonts</dir> <dir>/opt/local/share/fonts</dir>

</fontconfig> ----------------------------------------

2) install urw-fonts.

$ sudo port install urw-fonts

3) run fc-cache.

$ sudo fc-cache -fv

Thank you that solved the issue.

However, this raises several questions:

1) Why is the URW-fonts port not registered as dependency for GraphViz? 2) Why do I have to do the manual steps of editting fonts.conf and fc-cache when installing URW-fonts?

I'll take a look at this.

The reason that urw-fonts are not a dependency is that, according the the graphviz developers, they are not a dependency. This is probably an upstream documentation bug.

It should not be necessary to run the fc-cache program manually. (It should be done in a post-activate step in the urw-fonts portfile.) Don't know about editing the fonts.conf file, but it should not require hand editing except for very odd configurations.

The urw-fonts were added as a dependency so I am closing this bug.
