Hi Thomas, Thanks for the help (and to Vincent as well) :) In "/home/ubuntu/media_build/v4l/cec-core.c" changed row 142 from: "ret = cdev_device_add(&devnode->cdev, &devnode->dev);" to: "ret = device_add(&devnode->dev);" and row 186 from: "cdev_device_del(&devnode->cdev, &devnode->dev);" to: "device_del(&devnode->dev);" Even if I do that when I try to build it again (using ./build) it seems to reload / revert the cec-core.c to the original file since I still get these errors even though I saved the changes in Notepadqq: "/home/ubuntu/media_build/v4l/cec-core.c:142:8: error: implicit declaration of function 'cdev_device_add' [-Werror=implicit-function-declaration] ret = cdev_device_add(&devnode->cdev, &devnode->dev);" and "/home/ubuntu/media_build/v4l/cec-core.c:186:2: error: implicit declaration of function 'cdev_device_del' [-Werror=implicit-function-declaration] cdev_device_del(&devnode->cdev, &devnode->dev);" I am probably missing something here since it worked for you, would be grateful for your help :) /Karl Med vänlig hälsning / Best Regards - Karl Wallin karl.wallin.86@xxxxxxxxx P.S.
