Created attachment 489544 [details] patch to deconflict v4l headers The attached patch comments out enough of the component's v4l.h to make it build without error. I did NOT verify that the v4l driver actually works. (See Ubuntu discussion about disabling v4l in sane: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/87312 about which I would agree). The attached patch was actually made against sane-backends-1.0.22, but it should apply on 1.0.21. Of course, you're encouraged to roll forward to 1.0.22 so you can also support the Canon LiDE 210 scanner, if you want.
