[sane-devel] Canon pixma mp280, not sane supported.

[erik]

Ok, all sorted.

Thanks to the help of Rolf and Gernot.

The problem was laying in many different attempts to install 
sane-backends, some wrong linking, and after a total clean-up of all the 
installations, we noticed that the libsane.la was located in the folder

/usr/lib/i386-linux-gnu/libsane.la

So creating symbolic links to that file
$ cd /usr/lib/i386-linux-gnu
$ sudo ln -sf /usr/local/lib/libsane.so.1.0.24 libsane.so.1
$ sudo ln -sf /usr/local/lib/sane/libsane.la libsane.la
$ cd -

solved the problem.

Everything running smoothly now.

Please note that if xsane has problems in shutting down after using sudo 
xsane, remove the '~/.sane/' folder. And that little problem solved aswell.


Thanks!
