I've successfully installed DirectFB and have been using it with JPEGS
and keyboard input. But I must have a configuration problem in trying
to use the video provider with libflash.
I believe I successfully installed libflash (libflash-0.4.so.10,
libflash-0.4.so.10.0., libflash.la, libflash.so are in my /usr/local/lib
directory), but when I try to run my code I get the following error:
(*) Single Application Core. (with MMX support)
(*) DirectFB/misc/memcpy: using MMXEXT optimized memcpy()
(*) DirectFB/InputDevice: IMPS/2 Mouse 0.9 (convergence integrated media
GmbH)
(*) DirectFB/InputDevice: Keyboard 0.9 (convergence integrated media GmbH)
(*) MMX detected and enabled
(*) DirectFB/GraphicsDevice: MMX Software Rasterizer 0.5 (convergence
integrated media GmbH)
(!) DirectFB/core/fbdev: Panning display failed!
--> Invalid argument
(!) DirectFB/core/fbdev: Panning display failed!
--> Invalid argument
(#) DirectFBError [Failed creating video provider CreateVideoProvider]:
Interface implementation not available!
I tried adding "-llibflash" to my Makefile, but got the error:
/usr/bin/ld: cannot find -llibflash
When I do a "cat /proc/fb" I get
0 VESA VGA
1 VGA16 VGA
The code I wrote is based on what I could piece together from the
examples and tutorial code (df_video_particle.c and tutorial files using
still images) and is pasted at the end of this email.
I hope I've given you all of the pertinent information. Obviously, I'm
a newbie with Linux and with graphic drivers.
Thank you,
Amy
