Bug#831961: proftpd-dfsg: FTBFS with dpkg-buildpackage -A: make: *** No rule to make target 'build-indep'. Stop.

[Lucas Nussbaum]

Source: proftpd-dfsg
Version: 1.3.5a-1
Severity: important
Tags: stretch sid

Justification: FTBFS on amd64

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.  This rebuild was done by building only the architecture-independent
packages.  At the same time, a normal build succeeded, which points the
problem specifically to build-indep/binary-indep targets.


The specific error below usually happens when there is no build-indep target in
debian/rules.

If all the arch-independent packages are dummy transitional packages
released with jessie, the easy fix is to drop them now. If not, debian/rules
should be modified so that the build-indep and binary-indep target generates
the architecture independent packages (and only those).

After checking that both "dpkg-buildpackage -A" and "dpkg-buildpackage -B" work
properly, this package will be suitable to be uploaded in source-only form if
you wish.

I file this bug as severity: important, but Santiago Vila, who led this
effort (kudos to him), got approval from the release team to consider those
bugs RC for stretch. The severity will be increased to 'serious' shortly.
See #830997 for details.

Relevant part (hopefully):

> make: *** No rule to make target 'build-indep'.  Stop.

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
