# Rebuilding SANE (Canon Pixma MP730) for Ubuntu

I'm still seeking a new distro that takes less work than Gentoo but sits on the cutting edge and has reasonable package management. Kubuntu is potentially my next favourite distro and I'm currently running 9.04. I hate KDE4 but that's another story. Long live KDE3!

Unfortunately, the work we did in resolving the scanning problems for the Canon MP730 (pixma driver) didn't make it into SANE before 1.0.20 was released so probably even Ubuntu Karmic won't have MP730 support until SANE tags a new release. This leaves me with a problem: How do I rebuild the SANE packages to get my scanner supported?

Here are the steps to get the MP730 (and MP700) working in Ubuntu:

Update 29/8/09: Julien Blache, the maintainer of the Debian packages that Ubuntu builds on, has kindly incorporated the necessary patch starting with 1.0.20-6. You can save yourself a lot of trouble by simply using his packages. Look for a file named 'libsane_1.0.20-6_<arch>.deb' where <arch> is the architecture (amd64, i386 etc) of your machine, at http://ftp.debian.org/debian/pool/main/s/sane-backends/ then download and install it the same way as noted below. Jaunty users will likely get failed dependencies for libgphoto2 and libsane-extras but they can be safely ignored for the purposes of getting a working MP700/MP730 scanner. These packages do not require libusb to be installed.

$mkdir sane$ cd sane
$wget https://launchpad.net/ubuntu/karmic/+source/sane-backends/1.0.20-4ubuntu2/+files/{sane-backends_1.0.20.orig.tar.gz,sane-backends_1.0.20-4ubuntu2.diff.gz,sane-backends_1.0.20-4ubuntu2.dsc}  Download Nicolas' patch to sanei/sanei_usb.c that is attached to this page. $ wget http://waddles.org/sane-backends_1.0.20-fix_sanei_usb.patch_.txt

Download my debian/rules patch. Note that this patch will only produce a backend library for the pixma driver and will also prevent documentation being built with Latex which reduces the amount of extra package dependencies needed for building. If you want all backends to be built, just remove the first hunk of the patch or remove the BACKENDS="pixma" prefix to configure in debian/rules.

If you have everything installed already, you should end up with .deb files in your parent directory at this point, however, they will probably still be broken. I had to build it with libusb to make it work properly, so you should continue anyway. The step above is really to work out what dependencies are needed to build the packages. I'm going to force an override to avoid most of them anyway.

#### Install build dependencies

These are the packages I really needed to install:

$sudo apt-get install autotools-dev chrpath libusb-1.0-0-dev Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed: libusb-1.0-0 The following NEW packages will be installed: autotools-dev chrpath libusb-1.0-0 libusb-1.0-0-dev 0 upgraded, 4 newly installed, 0 to remove and 0 not upgraded.

Processing triggers for libc6 ... ldconfig deferred processing now taking place  #### Build the .deb packages $ dpkg-buildpackage -rfakeroot -b -d

Note the -d flag to override the missing dependencies. I have removed the output from this step as it is fairly pointless.

You should now have a set of .deb packages in your parent directory.

### Install

Install at least the libsane .deb file which contains the patched sanei/sanei_usb.c code. The others don't seem to be necessary but you may choose to install all of them anyway.

$sudo dpkg -i ../libsane_1.0.20-4ubuntu2_amd64.deb (Reading database ... 300705 files and directories currently installed.)
