Hi, I'm trying to run the first sample application (the one drawing a
horizontal line) on a ViXS XCode board (arc-uclibc).
I compiled DirectFB 1.2.3 as a _static_ library, so it should be
embedded into my executable file and I shouldn't need to copy anything
to the target device... is this correct?
Anyway I get the error:
[vixs]$ ./dfb_line
~~~~~~~~~~~~~~~~~~~~~~~~~~| DirectFB 1.2.3 |~~~~~~~~~~~~~~~~~~~~~~~~~~

(*) DirectFB/Core: Single Application Core. (2008-08-26 16:02)
(!) DirectFB/core/system: No system found!
dfb_line.c <31>:
(#) DirectFBError [DirectFBCreate(&dfb)]: No (suitable)
implementation found!
where dfb_line.c <31> is:
DFBCHECK(DirectFBCreate(&dfb));
Looking at the DirectFB code, I can see that:
* [src/directfb.c:193] DirectFBCreate() calls dfb_core_create( &core_dfb );
* [src/core/core.c:291] dfb_core_create() calls dfb_system_lookup();
* [src/core/system.c:273] dfb_system_lookup() calls
direct_modules_explore_directory( &dfb_core_systems );
* [lib/direct/modules.c:141] direct_modules_explore_directory() contains:
140 int
141 direct_modules_explore_directory( DirectModuleDir *directory )
142 {
143 #ifdef DYNAMIC_LINKING
144... ...<inactive code>...
248 #else
249 return 0;
250 #endif
251 }
so the "system_module" variable (defined into src/core/system.c) still
contains NULL (see src/core/system.c:82) causing the error.
Is there a way to properly initialize "system_module" when the
DYNAMIC_LINKING macro is disabled?
How can I use DirectFB as a statically compiled library?
BTW, these are my framebuffer settings:
[vixs]$ fbset -i
