Re: [Fonts]fontconfig.org
J Dear webmaster of fontconfig.org and webmaster of J xfree86.org/current/fonts.html, Juliusz Chroboczek I'm merely the author of the latter document. I am not a web site maintainer (which I take is what ``webmaster'' means). J 1) Please mention xft and FontConfig on this page, and describe what J they are for, and how they relate to the rest of the information on J www.xfree86.org/current/fonts.html The document does explicitly state that RENDER fonts are not described. They will be in 4.3.0 if I have time to write a section. Help is of course warmly welcome -- I didn't find anything on fontconfig.org that is suitable for verbatim theft. J In both cases you may consider to describe the mechanism of how a J font-family choice (e.g. on a web-page) propagates to a unique fully J specified X font-name of an installed font to be used to render the J font (on the web-page). Why do you believe that an XFree86 document should describe how your web browser works? Juliusz ___ Fonts mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/fonts

[Fonts]fontconfig
Hello, I've been trying to run mozilla with Xft on FreeBSD, and it always segfaulted on startup (report below). Then I found out I had to run fc-cache to make font.cache files in my fonts directories, and everything works fine. But I believe that fontconfig should not crash when these files are not present, should it? :) Thanks Tomas Pluskal gdb report from mozilla: #0 0x0 in ??
