Package: pbuilder
Version: 0.199+nmu3
Severity: wishlist
Cross building an i386 package on amd64 in general works fine but in the case
of linux-kernel-di-i386-2.6, which is Arch: i386 only, it is failing because
the check in /usr/lib/pbuilder/pbuilder-buildpackage-funcs:checkarchitecture()
fails:
"E: amd64 not in arch list or does not match any arch wildcards: i386"
This is because "dpkg-architecture -qDEB_HOST_ARCH" has returned amd64,
presumably because it runs in the host environment and not the chroot
environment.
I can workaround this by adding "export DEB_HOST_ARCH=i386" to ~/.pbuilderrc
but I cannot find e.g. an environment variable which would allow me to force
the correct arch automatically depending on the pbuilder command line (in
particular --architecture). Passing such a thing through would be quite useful.
Actually, just as I wrote the above it occurred that I can use:
export DEB_HOST_ARCH=$(uname -m | sed -e s/i.86/i386/ -e s/x86_64/amd64/)
in .pbuilderrc, since I use linux32 to invoke cross builds. Although this works
it would be nice if pbuilder took care of it automatically.
I suppose this related to #363088 but I didn't see this specific issue
discussed there so I've filed it separately.
BTW, I actually use cowbuilder but I tried pbuilder too and I think they are
equivalent in this matter.
Thanks,
Ian.
