ERROR: "usb_alloc_urb" [drivers/staging/easycap/easycap.ko] undefined! Adding "depends on USB" to EASYCAP is a good start. After that and enabling CONFIG_USB, build of easycap gets: ERROR: "video_register_device" [drivers/staging/easycap/easycap.ko] undefined! ERROR: "video_unregister_device" [drivers/staging/easycap/easycap.ko] undefined! because there is no media/video support enabled. Also no SOUND enabled, so I expect there to be build errors associated with sound also, meaning that the Kconfig file should probably modified with something like config EASYCAP + depends on USB && VIDEO_DEV && SND This is something that the driver author should know the answer to and submit a patch for. --- ~Randy *** Remember to use Documentation/SubmitChecklist when testing your code *** -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
