Hi all, I have that laptop, using Ubuntu, with the kernel headers installed. I have also a recent v4l-dvb tree. The dvb stuff is compiled directly from that tree using the headers and the DVB stick works very fine. Now, I have that Logitech quickcam messenger that needs this driver: http://home.mag.cx/messenger/ It wants to use the kernel headers I have and compile. But when I want to insert the module, it complains loudly: [31431.072034] quickcam: Unknown symbol video_devdata [31431.072436] quickcam: disagrees about version of symbol video_unregister_device [31431.072442] quickcam: Unknown symbol video_unregister_device [31431.072620] quickcam: disagrees about version of symbol video_register_device [31431.072624] quickcam: Unknown symbol video_register_device My guess is that it was compiled against the v4l version in the Ubuntu header, and that I have in fact a different v4l version in binary form because I compiled and installed a recent v4l-dvb tree. Could someone give me directions about how I could compile my webcam driver against the proper code? Thanks much, Nico _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
