Package: debhelper Version: 8.1.2 Multiarch support is (finally!) coming along nicely in both Ubuntu and Debian. (see https://launchpad.net/~vorlon/+archive/multiarch )
I'm not sure how closely you've been following the multiarch work, but it provides the ability to cleanly install libraries of multiple architectures. The multiarch-cross spec extension provides the functionality to use this for cross-building and resolving cross-dependencies. https://wiki.ubuntu.com/MultiarchSpec https://wiki.ubuntu.com/MultiarchCross We've been testing this work for use on armhf and armel and have come up with a nice patch for debhelper which makes the conversion of packages to be multiarch compliant very straighforward. We hope it meets with your approval. All library packages (and -dev packages) will need to be 'multiarchified' over time, so making this as easy as possible for maintainers is good. To convert a package the following is necessary: * all multiarch packages will need to be compat 8 and build-depend on debhelper >> 8.1.2 * debian/control gets the Multi-Arch fields added to relevant binary stanzas * debian/*.install files get modified, individually, with a token which debhelper can replace with the triplet. * export DEB_HOST_MULTIARCH ?= $(shell dpkg-architecture -qDEB_HOST_MULTIARCH) added to debian/rules (and tokens added as required) * The patch (from Daniel Silverstone), applied to debhelper (so that it can expand the token ${DEB_HOST_MULTIARCH}) Here is an example package, converted using the suggested patch: http://www.emdebian.org/trac/browser/current/multiarch/p/popt/trunk/debian http://ftp.uk.debian.org/emdebian-multiarch/pool/main/p/popt/ This has been tested inside a chroot with modified, experimental, versions of dpkg and lsb-base using vorlon's patches. These packages are available in the above emdebian-multiarch repository (although possibly only for amd64 but sources are included). The resulting packages cross-build in a MultiArch manner easily.
