[linux-dvb] Re: Problem in the testing program of the drivers

[cedric.picard@esial.uhp-nancy.fr]

In fact I think it come from the fact that my videodev driver doesnt want to load :
when i do ./inshmod-btt8xx.sh I have this message : 


caravelle:/linuxtv-dvb-1.1.1/build-2.4# ./insmod-bt8xx.sh start
Inserting DVB modules into kernelinsmod: videodev.o: No such file or directory
insmod: bttv.o: No such file or directory
insmod: a module named dvb-core already exists
insmod: a module named v4l1-compat already exists
insmod: a module named v4l2-common already exists
insmod: a module named video-buf already exists

./dst.o: ./dst.o: unresolved symbol bt878_device_control
./bt878.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including
invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
./dvb-bt8xx.o: ./dvb-bt8xx.o: unresolved symbol bt878_stop
./dvb-bt8xx.o: ./dvb-bt8xx.o: unresolved symbol bt878_start
./dvb-bt8xx.o: ./dvb-bt8xx.o: unresolved symbol bt878_num
./dvb-bt8xx.o: ./dvb-bt8xx.o: unresolved symbol bt878


There is effectivly not a videodev.o file in the folder, but there is one in my
sources. So i verified but the module was not loaded at start, i've try to load
it with modprobe it didnt work, and finaly i copied videodev.c and .o to my
dvb-build folder and it didn't work...

so someone can help me??
