release goal: Make the base system cross-buildable
Make the base system cross-buildable
====================================
It is very useful to be able to cross-build packages in Debian for
many reasons, especially around faster dev times on slow
architectures, and new ports. Making the whole archive crossbuildable
is a huge goal, but making the bottom 140 or so packages needed for a
port bootstrap cross-buildable is a reasonable goal. This work has
already been done in Ubuntu (Raring) and should be upstreamed into
Debian.
This goal is (somewhat) dependent on the CrossToolchains in the
Archive goal. (It can still be done with external toolchains if need
be, but it makes much more sense to have everything necessary
maintained in the archive).
Details
-------
This needs:
* all the build-deps of the bottom 140 packages to be multiarchified
(should be largely done already, or at least bugs filed)
* cross-building bugs in those packages fixed (many bugs already
filed, copy the rest over from ubuntu).
* autoconf cache variables to be set to supply info which can not be
correctly determined in a cross environment (using
dpkg-cross/cross-support) (Already done - needs testing)
* preferably availability of crossbuild-essential packages, and
corresponding toolchains in the archive.
optional extras
---------------
A cross-buildd running to check cross-buildability of packages should
be set up so that maintainers get timely info on breakages, otherwise
builds are quite likely to be broken when you want to use them. Like
this one: http://people.linaro.org/~wookey/buildd/
Targets
-------
In principle (and practice) this goal is architecture independent, but
in practice the scope can be limited to amd64->arm(hf/el) building if
it helps as that is where most current interest lies.
The package set needs to be checked but should be very close to:
