To the best of my knowledge, fltk::HELVETICA, COURIER, TIMES, etc., actually meant Helvetica, Courier, Times, etc., with the old font system, but with xft, they just mean sans, mono, serif, etc. And then in the fontconfig files, sans and friends are set to some specific font (e.g., looking quickly in mine, it seems that fonts.conf makes sans an alias for sans-serif, and then conf.d is full of files that specify that, for the sans-serif family, here are a bunch of specific font families in order of preference...).

Basically it gives your program support for things like anti-aliasing and TrueType fonts. Try building FLTK2 with ./configure --disable-xft and see what it does. ~Benjamin

If you check my prior email I have included an updated backtrace. On further examination of the source it looks to me like fltk is trying to hardcode my fonts?!?

I'm not sure what xft really does. And I wouldn't say they are antialiased because at font size 12 they look very jagged.

You said that this was a minimalist distribution, so I don't know whether fltk with xft configured is important to you...

In that case I must have fontconfig because in the text editor there are several fonts and font sizes I can pick from.

Ok, I'll compile with -g this afternoon after school. I don't have fontconfig on the target system. Is it required?
