Hi Dirk,
I am trying to add driver for sn9c102 based webcams. I have
included all the srource files from directory
l4/pkg/usb/examples/usbcam/contrib/linux/drivers/media/video/sn9c102 in
MAKEFILE of SRC directory. In linking stage , it says that it cant find some
refrences to param_set_bool' , 'vm_insert_page' , 'vmalloc_32_user' ,
'dev_name', 'complete_all' .
Should I add some static library in makefile which I have found under SRC
directory of USBCAM. Please notice that it is not giving any error in
compiliation stage of diffferent object files. It gives error only in
linking stage of usbcam.o .
Please help me .
Thanks
Tapas
