From the Trolltech pages referenced in the original how-to:
When Qt/Embedded applications run, they look for a file called $QTDIR/etc/fonts/fontdir or /usr/local/qt-embedded/etc/fonts/fontdir. This file defines the fonts available to the application. It has the following format:
name file renderer italic weight size flags
where:
name Helvetica, Times, etc.
file helvR0810.bdf, verdana.ttf, etc.
renderer BDF or TTF
italic y or n
weight 50 is Normal, 75 is Bold, etc.
size 0 for scalable or 10 times pointsize (eg. 120 for 12pt)
flags Flag characters:
s = smooth (anti-aliased)
u = unicode range when saving (default is Latin 1)
a = ascii range when saving (default is Latin 1)
Not easy to understand - especially as there is no example.
What it means is you only need four entries for each font (one each for normal, italic, bold and bold-italic)
ArialUnicode arial.ttf TTF n 50 0 su 80,100,120,140,160,180,200,240,360,480,720
ArialUnicode ariali.ttf TTF y 50 0 su 80,100,120,140,160,180,200,240,360,480,720
ArialUnicode arialbd.ttf TTF n 75 0 su 80,100,120,140,160,180,200,240,360,480,720
ArialUnicode arialbi.ttf TTF y 75 0 su 80,100,120,140,160,180,200,240,360,480,720
respectively (use the actual names of the font files on your system - I've used the names as they are on my windows machine). The extra "s" just before the u generates anti-aliased fonts - like smoothtimes - just leave it off if you don't like anti-aliasing. Also, I don't think you really want all those sizes as they get quite big - especially the larger fonts. OTOH, you know better than I do how much space you have spare.
Also, I don't think you need the -display Transformed:Rot270 if you run it on the Zaurus as it can automatically tell that the display is rotated. But remember - this is all from memory of something I did a long while back.
I don't think either of the messages you got are a cause for concern - the Zaurus makeqpf is built with some compromises which means it doesn't play nice...but it does work.
