Qfontdatabase: cannot find font directory

Qfontdatabase: cannot find font directory

Http://www.cuteqt.com/blog? P = 86

The error message is similar to the following:
Qfontdatabase: cannot find font directory/usr/local/trolltech/QtEmbedded-4.5.1/lib/fonts-Is QT installed correctly?

The most common cause is that the./configure command is not added during cross-compilation.
-Prefix option, resulting in the default installation path/usr/local/trolltech, even if you use NFS or copy to a path on your embedded device (such
/Foo), the path to be searched is/usr/local/trolltech.

The following is a demonstration. The directory I installed is the/usr/local/trolltech directory. Now I want to move it to the/usr/local/grolltech directory to see what the effect is.
$ MV/usr/local/trolltech/usr/local/grolltech
$ Qvfb &
$./Wiggly-qws

./Wiggly: Symbol lookup error:
./Wiggly: Undefined Symbol: _ zn7qwidget8qwseventep8qwsevent
This error can be avoided by specifying qtdir and LD_LIBRARY_PATH.
$ Export qtdir =/usr/local/grolltech/QtEmbedded-4.5.1
$ Export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: $ qtdir/lib

$./Wiggly-qws
Qfontdatabase: cannot find font directory/usr/local/trolltech/QtEmbedded-4.5.1/lib/fonts-Is QT installed correctly?
Solution: make a soft link to/usr/local/trolltech
$ Ln-S/usr/local/grolltech // usr/local/trolltech/
The same is true for embedding. commands like ln-S/mnt/usr/local/trolltech can be used.
