Correct. > That is, with the exception of lib32ffi-dev and friends; do you know (by > grepping Contents.gz or similar) that this is the complete list? Yes, this is a grep for 'usr/(lib|include)/i686-linux-gnu' in i386 and amd64 Contents.gz. > I don't think we are in a hurry to update the library stack by beta.

I have a pretty good set of libraries bootstrapped at https://launchpad.net/~vorlon/+archive/multiarch/, FWIW. It's actually enough to make flashplugin-installer cross-installable, but not co-installable with a desktop yet. > Question here: Once the new debhelper is in, will library packages will > be built for multiarch compatible paths by default, or does this need to > be enabled in debian/rules? If using dh(1) and your package uses autoconf, you can switch to compat level 9 and the package will build for multiarch paths by default. It's not safe to make this a completely automatic conversion: - a new pre-depends line needs to be added to the library to ensure that the virtual package 'multiarch-support' (provided by a compatible libc) is installed before we unpack libraries to the new path. - various embedded paths in debian/*.install, debian/*.links, etc will be invalidated, and not all of these will be detected at build time - patches may be needed for backwards-compatible plugin directory handling So I'll make this as easy as possible to switch, but it's not automatic. And I see no good way to simplify the conversion for cdbs, which doesn't use dh_auto_configure. I guess cdbs could itself key on debian/compat >= 9 and pass the --libdir option automatically, but as this behavior change would not be nearly as discoverable with cdbs as it is with debhelper, I prefer not to get too clever. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
