This isn't nice but it isn't not unusual either. If you want to see some
more warnings try ./configure --enable-warnings :^) I try to fix the
warnings in my backend and the global parts of sane I understand. The rest
must be done by the other backend maintainers. But not all backends are

There are many different backends to compile and link ...
If you know what backend(s) you want to use you can change the
"PRELOADABLE_BACKENDS=" line in backend/Makefile to only include the
backends you need.

I don't have much experience with cameras but I think if your camera isn't
supported by the kernel you won't have success with SANE. SANE has direct
support for some cameras (see README) but the rest is supported by the v4l
backend which is an interface to the Video for Linux kernel driver. So if
your camera doesn't work with e.g. KWinTv and Video for Linux you probably
won't have success with SANE.

Is it found by the kernel?

I don't think that gtk is the reason. Since 2 1/2 years nobody touched xcam
and it's without a maintainer. Would you like to maintain this program?
