Ich versuche mal, dfb neu zu compilieren.

DirectFB/autogen ist durchgelaufen.
make steigt aus:

...
gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../../include -I../../lib -I../../include -I../../lib -DDATADIR=\"/usr/local/share/directfb-0.9.25\" -DMODULEDIR=\"/usr/local/lib/directfb-0.9.25\" -D_REENTRANT -Wall -O3 -ffast-math -pipe -D_GNU_SOURCE -Werror-implicit-function-declaration -MT system.lo -MD -MP -MF .deps/system.Tpo -c system.c -fPIC -DPIC -o .libs/system.o

make[1]: *** [all-recursive] Error 1

make: *** [all] Error 2


Doch noch die aktuelle Version aus dem cvs geholt:
cvs -d :pserver:anonymous@git.directfb.org:/git/directfb/core/DirectFB.git co -d DirectFB master


Mit der geht es leider auch nicht:
gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../../include -I../../lib -I../../include -I../../lib -DDATADIR=\"/usr/local/share/directfb-0.9.25\" -DMODULEDIR=\"/usr/local/lib/directfb-0.9.25\" -D_REENTRANT -Wall -O3 -ffast-math -pipe -D_GNU_SOURCE -Werror-implicit-function-declaration -MT system.lo -MD -MP -MF .deps/system.Tpo -c system.c -fPIC -DPIC -o .libs/system.o

So, den make-Fehler habe ich jetzt weg bekommen. Ich habe die system.c mit der aktuellen Version von http://git.directfb.org/?p=core/DirectFB.git;a=blob;f=lib/direct/system.c;h=8dd3f125d6e757073a0916c27577581c19b83bfb;hb=master ersetzt. Die schien besser mit dem neuen reese-System zu harmonieren.

Im STartscript stand ein rmmod -f.
Die dfb-module bzw. der Kernel haben das gewalttätige Entfernen offfenbar nicht vertragen.
