Bug#806631: libosmium: FTBFS when built with dpkg-buildpackage -A (cd: can't cd to build)

[Santiago Vila]

Package: src:libosmium
Version: 2.4.1-3
User: sanvila at debian.org
Usertags: binary-indep
Severity: important

Dear maintainer:

I tried to build this package with "dpkg-buildpackage -A"
(i.e. only architecture-independent packages), and it failed:

--------------------------------------------------------------------------------
[...]
 debian/rules build-indep
dh build-indep --parallel
   dh_testdir -i -O--parallel
   debian/rules override_dh_auto_configure
make[1]: Entering directory '/<<PKGBUILDDIR>>'
dh_auto_configure -- -DCMAKE_VERBOSE_MAKEFILE=1
make[1]: Leaving directory '/<<PKGBUILDDIR>>'
   debian/rules override_dh_auto_build-indep
make[1]: Entering directory '/<<PKGBUILDDIR>>'
(cd build && /usr/bin/make doc)
/bin/sh: 1: cd: can't cd to build
debian/rules:20: recipe for target 'override_dh_auto_build-indep' failed
make[1]: *** [override_dh_auto_build-indep] Error 2
make[1]: Leaving directory '/<<PKGBUILDDIR>>'
debian/rules:11: recipe for target 'build-indep' failed
make: *** [build-indep] Error 2
dpkg-buildpackage: error: debian/rules build-indep gave error exit status 2
--------------------------------------------------------------------------------

Sorry not to have a fix, as I am reporting many bugs similar to
this one. The common hints are:

* If the only architecture-independent packages are dummy transitional
ones and they were released with jessie, the easy fix is to drop them
now.

* When using "dh", it is allowed to use (independently)
optional targets override_dh_foo-arch and override_dh_foo-indep
(for several values of "foo").


Once that both "dpkg-buildpackage -A" and "dpkg-buildpackage -B" work
properly, the package would be suitable to be uploaded in source-only
form if you wish.

Thanks.
