I thank you!

I tried it and compile failed. Perhaps I'm to dump...I don't know
Is it possible to disable compiling all backends except the canon backend?
I think the compiling failed in another backend than the canon backend.

Same here. Compiling failed :-(
Still looking for a way to compile only the canon backend.

Not really.. I ran into compile errors. 
I'm not really experienced in compiling beside the configure-make-makeinstall steps

Compiling was succesfully, but whan I try to scan, same behavior as in sane-backends above 1.0.11
I mean, no success :-(

Not really helpful, I know...
Anything else, what I can do?

They are in the cc-field
