pbuilder-dist does not build foreign architecture

[Rex Tsai]

Reproduce -
$ apt-get source flash-kernel
$ pbuilder-dist oneiric armel build flash-kernel*dsc
I: Logging to /home/chihchun/pbuilder/oneiric-armel_result/last_operation.log
E: amd64 not in arch list or does not match any arch wildcards: arm armel armeb armhf

In pbuilder (/usr/lib/pbuilder/pbuilder-buildpackage-funcs), it checks supported architecture. However, it's always failed if the packages does not support any or all architectures.

That sounds like a pbuilder bug, rather than pbuilder-dist.

My understanding is that sbuild does have support for cross-architecture build chroots. sbuild is recommended over pbuilder as a build tool.

[Rex Tsai (chihchun)]

The pupose of sbuild and pbuilder are differnt.

You can build pacakge with exist chroot with sbuild, but pbuilder can help you build from a clean chroot and install build-depnds for you.

[Dimitri John Ledkov (xnox)]

Rex Tsai, sbuild builds from clean environment *and* installs dependencies as well.

Please try mk-sbuild . Both tools are made for the same job.

[Mattia Rizzolo (mapreri)]

this is not a pbuilder bug:
pbuilder does not check if he should build the package or not at all, it just hands the .dsc to dpkg-buildpackage after satisfying build-deps.

Interestingly enough, I trying to look up "in arch list or does not match any arch wildcards" in codesearch.d.n, and the only results have been from sbuild and xbuilder.

Since I'm confused, I'm reassigning this back to ubuntu-dev-tools.
