   Package: debhelper   
   Version: 13.29   
   Severity: normal   
      
   xtensor 0.27.1-1 provides new config files   
     etc/xeus-cpp/tags.d/xtensor.json   
     usr/share/xeus-cpp/tagfiles/xtensor.tag   
      
   I added them to xtensor's debian/libxtensor-dev.install, and   
   dh_installs them.   
      
   But the build fails with dh_missing reporting:   
      
   dh_missing: warning: etc/xeus-cpp/tags.d/xtensor.json exists in debian/tmp but   
   is not installed to anywhere   
   dh_missing: warning: A file with an equivalent path was found but did not get   
   installed. Note that dh_install prefers paths in ./ over paths in ./debian/tmp.   
   dh_missing: error: missing files, aborting   
   	The following debhelper tools have reported what they installed (with files   
   per package)   
   	 * dh_install: libxtensor-dev (6), xtensor-dev (0), xtensor-doc (0)   
   	 * dh_installdocs: libxtensor-dev (0), xtensor-dev (0), xtensor-doc (0)   
   	If the missing files are installed by another tool, please file a bug against   
   it.   
   	When filing the report, if the tool is not part of debhelper itself, please   
   reference the   
   	"Logging helpers and dh_missing" section from the "PROGRAMMING" guide for   
   debhelper (10.6.3+).   
   	  (in the debhelper package: /usr/share/doc/debhelper/PROGRAMMING.md.gz)   
   	Be sure to test with dpkg-buildpackage -A/-B as the results may vary when   
   only a subset is built   
   	If the omission is intentional or no other helper can take care of this   
   consider adding the   
   	paths to debian/not-installed.   
   make: *** [debian/rules:39: binary] Error 255   
   dpkg-buildpackage: error: debian/rules binary subprocess failed with exit   
   status 2   
      
      
   But etc/xeus-cpp/tags.d/xtensor.json was indeed installed by dh_install:   
      
   $ ls -l debian/*/etc/xeus-cpp/tags.d/xtensor.json   
   -rw-r--r-- 1 dd dd 85 Feb  9 02:46 debian/libxtensor-dev/etc/xeu   
   -cpp/tags.d/xtensor.json   
   -rw-r--r-- 1 dd dd 85 Feb  9 02:46 debian/tmp/etc/xeus-cpp/tags.d/xtensor.json   
      
      
   So dh_missing is giving a false error.   
      
   If I prepend ./ in libxtensor-dev.install, as   
     ./etc/xeus-cpp/tags.d/xtensor.json   
   then dh_missing still fails (and dh_install still works)   
      
   I can work around the bug by prepending debian/tmp in   
   libxtensor-dev.install, as   
      
     debian/tmp/etc/xeus-cpp/tags.d/xtensor.json   
      
   But this makes the line inconsistent with the other lines,   
   which are using usr/...
