No wonder since you specify "usb_vision/quickcam" as the subdirectory of "video" - and since that directory probably doesn't exist, it will probably also don't find a Jamfile in there :-) So you have to alter the Jamfile in "video" to look like this: SubDir HAIKU_TOP src add-ons kernel drivers video ; SubInclude HAIKU_TOP src add-ons kernel drivers video usb_vision ; SubInclude HAIKU_TOP src add-ons kernel drivers video quickcam ; Bye, Axel.
