Hello. I've downloaded the sources of v4l-dvb and built them (I have A16D tuner which is not supported in "main" kernel). However, saa7134-alsa wasn't built. "make xconfig" also had this module unchecked (and unavailable to check). I've found that this is because of "ubuntu" way of building system: the generic kernel config file doesn't has ALSA subsystem checked. Actually you have to install two modules: linux-image and linux-ubuntu-modules. First contains "minimal" kernel with just essential options - and .config file corresponding to it. linux-ubuntu-modules contains everything else - including all ALSA staff, etc. The comment in media/saa7134/BOM said: # # All of the saa7134 sources were copied directly from the 2.6.24 kernel. # # The ALSA depedent modules must be built in LUM since ALSA is # disabled in the kernel. Not all of the saa7134 modules are depedent on # ALSA, but it just seemed simpler to grab the whole pile. # # Note that the compilation of the saa7134 sources is also dependent on # the kernel headers packages containing some internal header files # from the drivers/media directories. # # Tim Gardner Apr 3, 2008. So, my problem is that I can't build v4l-dvb saa7134-alsa module because ALSA is disabled in kernel. If I enable the alsa in kernel config, it said this during stage 2 of building modules: WARNING: "snd_pcm_lib_ioctl" [/home/alexey/v4l-dvb-3366cefd1b57/v4l/saa7134-alsa.ko] undefined!

I believe that I need to mess some way the v4l-dvb with sources of linux-ubuntu-modules - to point some way that the ALSA is exists, and it is not in the kernel. but in the ubuntu-modules. Am I right? How to do it? _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
