Hi! I am trying to build Video4Linux-dvb for my NAS (D-Link DNS-323) so I can use it as a mythtv-backend for recording TV. The NAS has an ARM processor running a 2.6.12.6 kernel on it: root@DNS-323:~# uname -a Linux DNS-323 2.6.12.6-arm1 #31 Thu Mar 26 18:20:41 CST 2009 armv5tejl unknown I have set up and tested a toolchain for cross-compilation and a configured kernel source-tree. Now I am trying to compile the v4l-dvb kernel modules needed to get my dvb-usb stick (MSI Digivox mini II V3.0, an AF9015 based stick) running. I already replaced all the mutexes by semaphors, all the kzalloc() by kmalloc() and memset() and did some other small adjustments in the source-code. Now what is left are the calls to class_destroy(...), class_create(...) class_device_create(...) and class_device_destroy(...) in dvbdev.c which are non-existent in this kernel version. I think it might be the change from devfs to udev? I tried to compare different versions of the kernel-files and the v4l-dvb files, but the changes seem quite fundamental and this is the first time I am trying to build and modify some kernel modules, so any help would be most welcome. These are the interesting Parts of the build: CC [M] /home/moritz/v4l-dvb/v4l/dvbdev.o In file included from /home/moritz/v4l-dvb/v4l/dvbdev.c:34: /home/moritz/v4l-dvb/v4l/compat.h:442: warning: `struct snd_card' declared inside parameter list /home/moritz/v4l-dvb/v4l/compat.h:442: warning: its scope is only this definition or declaration, which is probably not what you want /home/moritz/v4l-dvb/v4l/compat.h: In function `snd_card_create': /home/moritz/v4l-dvb/v4l/compat.h:444: warning: assignment from incompatible pointer type /home/moritz/v4l-dvb/v4l/dvbdev.c: In function `dvb_register_device': /home/moritz/v4l-dvb/v4l/dvbdev.c:282: warning: implicit declaration of function `class_device_create' /home/moritz/v4l-dvb/v4l/dvbdev.c:282: warning: assignment makes pointer from integer without a cast /home/moritz/v4l-dvb/v4l/dvbdev.c: In function `dvb_unregister_device': /home/moritz/v4l-dvb/v4l/dvbdev.c:309: warning: implicit declaration of function `class_device_destroy' /home/moritz/v4l-dvb/v4l/dvbdev.c: In function `init_dvbdev': /home/moritz/v4l-dvb/v4l/dvbdev.c:498: warning: implicit declaration of function `class_create' /home/moritz/v4l-dvb/v4l/dvbdev.c:498: warning: assignment makes pointer from integer without a cast /home/moritz/v4l-dvb/v4l/dvbdev.c: In function `exit_dvbdev': /home/moritz/v4l-dvb/v4l/dvbdev.c:517: warning: implicit declaration of function `class_destroy' [...] Building modules, stage 2.
