[Foxgui-users] Font Issue on RedHat version 6.5

[Julia Dudascik (Contractor)]

All

I built the fox source code on RedHat 5.8 previously, and then my
application statically linked with the fox libraries. Everything worked
fine.

Recently I built the fox source code on RedHat 6.5, and statically linked
my application with the fox libraries. When I run my application, I get the
following error message:

glXUseXftFont: unable to render glyph.

Do you know what would cause this error message? Is there an additional
library I need to link with, that was not listed when I ran "fox-config
--libs"? Is there something missing on our system that we need to use this?

Thank you
Julia

The only thing I can think of is if you happen to have a non-contiguous
glyph-set, i.e. there are gaps in the code-points to glyphs mappings.

glXuseXftFont() builds a contiguous display list, from code points starting
from first up to first + count. I assume you've interrogated the font
to ensure that the font indeed supports all the code points in that range?
