so guide me ,,, any answer will appreciated...

Until you get the compile to find the all the include files you are not going to succeed. The locate(1) command will help you find the include files if they are installed on your system.

The mentions of /dev/fb/0 and /dev/fb0 looks like it is referring to a Solaris framebuffers (graphics card by another name for a P.C.) to me; you I think will have a /dev/video so you could try setting FRAMEBUFFER to /dev/video before running dfbinfo?

Hi Sir,

i am trying from 4hours to set the Frame buffer to /dev/video ..
but i dint get how to set that,,,
pls guide me for That...it will appreciated ..

DirectFBInit (&argc, &argv);

}
