[Pkg-phototools-devel] Bug#929470: facedetect: Facedetect can depend on opencv-data instead of libopencv-dev

[Dominik Stadler]

Package: facedetect
Version: 0.1-2
Severity: normal
Tags: patch

This package currently has libopencv-dev as a runtime-dependency. 

However the README states that either opencv-data or libopencv-dev need to be installed.

In fact, when scanning the sources of the package, it seems only stuff from /usr/share/opencv 
is required, which is provided by opencv-data.

So the dependencies of facedetect can be reduced a lot by only depending on opencv-data. 

Otherwise many development packages are dragged in as part of libopencv-data.
