Hi!
I'm building a DVB box from the scratch using Gentoo (what else?). I intend to use vdr as my pvr software, using vdr-softdevice in DirectFB mode. I do not wish to use X, as it create a yet another set of problems and unnecessary complexity. I'm having trouble with the DirectFB versions distributed via portage. Basic framebuffer itself works like a charm, but DirectFB doesn't. I've already scoured through the web, usenet and README's but found nothing that I could use.
My hardware:
AMD Duron 750Mhz, 320MB memory, 80GB HD, Matrox G200, Technotrend C-1500 dvb-c card
Software:
Kernel 2.6.19-r5 (gentoo patched)
DirectFB 0.9.25.1 / DirectFB 1.0.0
DFB++ 0.9.23 / DirectFB 0.9.25
If I try launching _any_ DirectFB app (vdr w/ softdevice, mplayer, dfbg, dfb demo programs etc.) I get errors like this:
(*) DirectFB/Core: Single Application Core. (2007-04-14 16:37)
(!) Direct/Modules: Could not open module directory `/usr/lib/directfb-1.0-0/systems'!
--> No such file or directory
(!) DirectFB/core/system: No system found!
(#) DirectFBError [DirectFBCreate() failed]: No (suitable) implementation found!
/usr/lib/directfb-1.0.0 contains only these:
gfxdrivers inputdrivers interfaces wm
If I create a link from gfxdrivers to system, I will get this instead:
(*) DirectFB/Core: Single Application Core. (2007-04-14 16:37)
(!) Direct/Modules: Module 'libdirectfb_matrox.so' did not register itself after loading! Trying default module constructor...
(!) Direct/Modules: ... even did not register after explicitly calling the module constructor!
(!) DirectFB/core/system: No system found!
(#) DirectFBError [DirectFBCreate() failed]: No (suitable) implementation found!
If I have the link systems -> gfxdrivers, this is what strace gives me (only essential parts):
---snip---
open("/usr/lib/directfb-1.0-0/systems/libdirectfb_matrox.so", O_RDONLY) = 4
---snip---
open("/etc/ld.so.cache", O_RDONLY) = 4
---snip---
open("/lib/libsysfs.so.2", O_RDONLY) = 4
---snip---
write(2, "(!) Direct/Modules: Module \'libd"..., 127(!) Direct/Modules: Module 'libdirectfb_matrox.so' did not re
gister itself after loading! Trying default module constructor...
) = 127
write(2, "(!) Direct/Modules: ... even did"..., 95(!) Direct/Modules: ... even did not register after explicitly
calling the module constructor!
) = 95
If I install vanilla directfb-1.0.0 from
http://www.directfb.org I don't get these messages. I have not yet thoroughly tested whether I could use vanilla directfb instead, but I'd rather not because using it will bring other problems along.
Here are some hopefully relevant pieces of information about my system:
