How to update SANE for Canoscan LiDE 25 (Ubuntu)


I'm running Ubuntu breezy (RC) which comes with Sane 1.0.15 installed as a deb package. My Canoscan LiDE 25 is apparently supported by the CVS version of SANE (which will eventually be 1.0.17) but obviously I'd quite like to try and make it work now.

Since I assumed you couldn't have two versions of libsane installed (is this right?), I removed the old libsane using apt-get. Unfortunately this also removes xsane since it is a dependency.

I then:

- Downloaded the latest nightly source code for sane-backends
- Installed it
- Ran sane-find-scanner and scanimage -L

My scanner seems to be picked up after this which is great. Unfortunately I can't re-install XSane to actually scan! The reason is that it would re-install the old libsane deb package dependency which I thought would wipe out the version I compiled myself?

My initial thought was to try and install xsane manually as well, but after compiling and trying to run it, all I got was a seg fault.

I'm now officially out of my depth! Does anybody here know how to install the latest SANE from cvs without upsetting Ubuntu's package manager and keeping xsane installed?

Thanks in advance

I take it then, you can scan from commandline OK?

The easiest thing to do is to reinstall xsane (yes, with the old driverlists) and then recompile the new ones over the top.

Keeping the old version is only a problem if the backends are stored in a different place. When you compile the sane-project backends, they overwrite the old installation.

Alternatively...
You can copy the backend you need, with it's .conf file, no another directory - reinstall xsane, then move the saved backend back.

You can reinstall xsane and then follow the instructions in the sane-project FAQ to only install the one backend you need updated.

You can install xsane from source.

... and many more.
