Hello everyone. I am trying to build v4l-dvb device drivers according to instruction on linuxTV wiki http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers but it fails when compiling dvb_frontend.c This is what I get: /home/tomislav/src/v4l-dvb-e341e9e85af2/v4l/dvb_frontend.c: In function 'dvb_frontend_stop': /home/tomislav/src/v4l-dvb-e341e9e85af2/v4l/dvb_frontend.c:707: error: implicit declaration of function 'init_MUTEX' make[3]: *** [/home/tomislav/src/v4l-dvb-e341e9e85af2/v4l/dvb_frontend.o] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [_module_/home/tomislav/src/v4l-dvb-e341e9e85af2/v4l] Error 2 make[2]: Leaving directory `/usr/src/linux-headers-2.6.31-9-rt' Kerner version is Linux version 2.6.31-9-rt (buildd@yellow) (gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu8) ) #152-Ubuntu SMP PREEMPT RT Thu Oct 15 13:22:24 UTC 2009 I've searched everywhere, and I haven't find similar problem. Can someone give me a hint what am I doing wrong. And just to say, I'm far from being a linux expert. :) Thank you, Tomislav -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
