Hi Michele, I also had the same problem .... To fix it I changed videodev.h and videodevX.c. The lines containing: video_register_device(struct video_device *, int type); into: video_register_device(struct video_device *, int type, int nr); This is how video_register_device is declared in the kernel. And it seems to work. Regards, David P.S. I want to thank everybody working on and with open source software. In particular Justin for his work on the bttv2 driver .... -----Original Message----- From: video4linux-list-admin@xxxxxxxxxx [mailto:video4linux-list-admin@xxxxxxxxxx]On Behalf Of Michele Slocovich Sent: Wednesday, June 27, 2001 9:02 PM To: 'video4linux-list@xxxxxxxxxx' Subject: RE: v4l2 for 2.4.x kernels replaces videodev.h so that kernel no longer compiles kernel (2.4.5, patched for i2c 2.6.0) still won-t compile. videodevX still working fine together with bttv2 out onto xawtv.
