Introduction to DirectFB

DirectFB is a graphics library on top of the Linux frame buffer device. It offers maximum hardware accelerated performance at a minimum of resource usage and overhead.

Package information

Additional downloads

DirectFB dependencies

Required

FreeType-2.1.7, libjpeg-6b and libpng-1.2.5

Optional

SDL-1.2.7, libmpeg3-1.5.4 pkgconfig-0.15.0, Imlib2-1.1.0, OpenQuicktime-1.0 and Avifile-0.7.38

Installation of DirectFB

[Note]

Note

DirectFB needs a Linux kernel with frame buffer support. Check the documentation in the kernel tree (/usr/src/linux/Documentation/fb/) on how to enable the frame buffer device for your graphics card.

Install DirectFB by running the following commands: 

./configure --prefix=/usr &&
make &&
make install

If you decided to add any optional image and video providers, then you have to install the DirectFB-extra package too: 

./configure --prefix=/usr &&
make &&
make install
[Note]

Note

The current version of avifile does not work with DirectFB. You have to use the avifile version which can be found at http://www.directfb.org/download/contrib/ or alternatively disable the avifile video provider by calling configure with --disable-avifile.

Configuring DirectFB

Config files

/etc/directfbrc, ~/.directfbrc

Configuration information

DirectFB is shipped with reasonable defaults but you might have to tweak things. There are several ways to do this. You may edit the system-wide configuration file /etc/directfbrc, the user-specific ~/.directfbrc or you may configure the DirectFB application via the command-line. Consult the directfbrc(5) manual page for details.
