This is a multiarch issue I had not considered before. Have you seen it? I never wanted to be a "cross compiler", I really only want to build amd64. But I have some i386 libraries for a particular program (acroread).
I've just learned that, if I build amd64 packages, I can't install them for testing because I've not also built the i386 packages. pauljohn@pols-124:cairo-1.12.10$ sudo dpkg -i libcairo2_1.12.10-1_amd64.deb (Reading database ... 311111 files and directories currently installed.) Preparing to replace libcairo2:amd64 1.12.10-1 (using libcairo2_1.12.10-1_amd64.deb) ... Unpacking replacement libcairo2:amd64 ... dpkg: error processing libcairo2:amd64 (--install): package libcairo2:amd64 1.12.10-1 cannot be configured because libcairo2:i386 is at a different version (1.12.2-2) Errors were encountered while processing: libcairo2:amd64 That's really inconvenient! I don't understand why there has to be a linkage between the shared library versions on amd64 and i386. Aren't they separate? You ask "why cairo?" I am curious to know if a new libcairo2 fixes a little bug in Evince (invisible vertical quotes). So I worked through the packaging for cairo-1.12.10. dpkg-buildpackage -rfakeroot gives me the goods (after fiddling some patch fuzz): cairo-perf-utils_1.12.10-1_amd64.deb libcairo2_1.12.10-1_amd64.deb libcairo2-dbg_1.12.10-1_amd64.deb libcairo2-dev_1.12.10-1_amd64.deb libcairo2-doc_1.12.10-1_all.deb libcairo2-udeb_1.12.10-1_amd64.udeb libcairo-gobject2_1.12.10-1_amd64.deb libcairo-script-interpreter2_1.12.10-1_amd64.deb I expect your answer will be "yes, it really is that hard, you have to learn how to compile for i386 too". I'm trying (http://wiki.debian.org/Multiarch/HOWTO), but not making progress. I'm like a collection of monkies trying to type the Bible at random, I'm afraid. pauljohn@pols-124:~$ sudo apt-get build-dep -a i386 libcairo2 [sudo] password for pauljohn: Reading package lists... Done Building dependency tree Reading state information...

Try 'apt-get -f inst And I stop there, seeing that the failed install of the amd64 packages has now broken everything. I need to back-track to find a way to fix that and then hide in the safety of Wheezy. -- Paul E. Johnson Professor, Political Science Assoc.
