I am running a Test Code from DFBTutorials-0.5.0.
Filename: Simple.c
Code Snippet follows:
int main (int argc, char **argv)
{
DFBSurfaceDescription dsc;
DFBCHECK (DirectFBInit (&argc, &argv));
DFBCHECK (DirectFBCreate (&dfb));
DFBCHECK (dfb->SetCooperativeLevel (dfb, DFSCL_FULLSCREEN));
dsc.flags = DSDESC_CAPS;
dsc.caps = DSCAPS_PRIMARY | DSCAPS_FLIPPING;
DFBCHECK (dfb->CreateSurface( dfb, &dsc, &primary ));
DFBCHECK (primary->GetSize (primary, &screen_width, &screen_height));
DFBCHECK (primary->FillRectangle (primary, 0, 0, screen_width, screen_height));
DFBCHECK (primary->SetColor (primary, 0x80, 0x80, 0xff, 0xff));
DFBCHECK (primary->DrawLine (primary, 0, screen_height / 2,
screen_width - 1, screen_height / 2));
DFBCHECK (primary->Flip (primary, NULL, 0));
sleep (5);
primary->Release( primary );
dfb->Release( dfb );
return 23;
}
Program is crashing on DFBCHECK (DirectFBCreate (&dfb));

Hello,
For cross compilation, I am doing following steps
1) configure
./configure CC=arm_v5t_le-gcc
LDFLAGS="-L/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/target/lib/"
CFLAGS="-I/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/include/"
PKG_CONFIG=/home/Harris/workdir/filesys/usr/lib/pkgconfig/
--prefix=/home/Harris/workdir/filesys/usr
--exec-prefix=/home/Harris/workdir/filesys/usr --build=i686 --host=arm-linux
--enable-x11=no --with-gfxdrivers=davinci --with-inputdrivers=none
--enable-fbdev=yes --enable-png=no --enable-freetype=no --enable-jpeg=no
where, /home/Harris/workdir/filesys is out target file system.
2) make ; make install
I have also checked putting data on /dev/fb0 [echo "aaaaaaaaaaaaaaaaaaaa"
>/dev/fb0]
I am able to see the data after wrinting on int. [cat /dev/fb0]
Please Help...!!!
Thanks,
Ujjal
