Comment 29 for bug 164640

Sylvain, your ported patch requires definitions that come from Ubuntu's supplementary patch to fontconfig. You either need to get that patch into fontconfig upstream or remove the added options from the cairo patch.

As an added note, even after patching fontconfig and building from your patch, the fontconfig additions don't seem to have any effect. In fact, the original Ubuntu-modified changeset to Cairo has a significant error where they use FC_LCD_FILTER_* definitions where they should be using FT_LCD_FILTER_* to pass to FT_Library_SetLcdFilter. I checked the headers, and the definitions don't correspond. This leads me to believe that their changes never did what they were supposed to in the first place.
