Bug#805993: apron: FTBFS when built with dpkg-buildpackage -A (No such file or directory)

[Santiago Vila]

Greetings.

I have the ok from the Release Managers to consider this issue as RC
for stretch. I'm going to wait at least one week before raising
this to "serious".

There is a patch available for this bug. If you need someone to make
an upload, please ask for a sponsor in debian-mentors.

Thanks.

Hi.

The reason it fails is that it tries to copy libapron.override to a
directory which does only exist when creating the architecture-dependent
packages.

There is an easy fix for that: Drop the "cp" line from debian/rules,
rename "libapron.override" to "libapron.lintian-overrides" and let
"dh" handle the file automatically.

Patch follows.

Thanks.commit 69e2b2e8502fc819517ee125654e1c9a0566dc48

Dear maintainer:

I tried to build this package with "dpkg-buildpackage -A"

Sorry not to have a fix, as I am reporting many bugs similar to
this one, but I can give some general hints:

* 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 binary-indep
target works in all cases, even when binary-arch is not used (this is
what the "Architecture: all" autobuilder does). For that:

* If you are using debhelper, you might want to use options -a and -i
for dh_* commands so that they do not act on packages they do not
have to act.

* Also, if you are using dh, the (independently) optional targets
override_dh_foo-arch and override_dh_foo-indep (for several values
of "foo") may be useful to write a debian/rules which behaves exactly
as desired.


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 (you might want to try it).

Thanks.
