Hi:
I'm a novice to DirectFB, and I have successfully cross compiled the
DirectFB(version:1.1.1) and GTK-DirectFB(version:2.12.8) for my davinci
6446.But I encounter some problems when I try to run some DirectFB or
GTK-DirectFB testing programs.
If I just ran a very simple DirectFB testing program to draw a line
or a rectangle, it could draw the line or rectangle on my screen
successfully.But when I tried any complexer testing programs (for
example, create a window on the display layer and do some operations),
it failed to display.Here is the log message:

It puzzled me so much, and I couldn't find the reason.I
use these compile options to cross compile the DirectFB:
./configure --enable-osx=no --enable-x11=no --enable-mmx=yes
--enable-fbdev=yes --enable-sdl=no --enable-video4linux=yes
--enable-video4linux2=yes --enable-zlib=yes --enable-jpeg=yes
--enable-png=yes --enable-gif=yes --enable-freetype=yes
--with-gfxdrivers=davinci
--with-inputdrivers=linuxinput,ps2mouse,keyboard --with-tests
--host=arm-linux --build=i386-linux --target=arm-linux --prefix=/arm
--enable-multi --enable-debug-support=yes --enable-debug=yes
--enable-extra-warnings=yes --enable-unique=yes
Is there anything wrong ? Or I have missed something ?
