I cannot reproduce this. It works fine for me. I am running 32bit and 64bit applications using fontconfig alternatetly and they don't trample each others data in ~/.fonts.cache-2. > Note also that the line you patched was a fix to 'severe perf > regression when global fonts.cache-2 files are missing', which you and > I tested back in October 2005.

Deleting it when the current architecture cannot be found cannot be correct in my opinion. -- Mike FABIAN <mfabian@xxxxxxx> http://www.suse.de/~mfabian 睡眠不足はいい仕事の敵だ。 _______________________________________________ Fontconfig mailing list Fontconfig@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/fontconfig
