please reject proj, the issue is that pcl needs an explicit dependency, because vtk6 lost the direct one for the -dev package.
The really nice fix would have been to cherry-pick the vtk6 revert to use the internal proj library, but this is unfeasible since it is an ABI change. (see debian bug: #819741) now, the smartest solution I could think is to add libproj-dev to pcl dependencies, even if this might result in an ABI break too. https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/locutusofborg-ppa/+packages please test this package and specially pcl reverse-dependencies in xenial with this updated version fixing vtk6 will require checks/rebuilds of ~10 reverse-dependencies (many of them might have been already built with the old vtk with embedded proj, so no change for them), while fixing pcl means only one reverse-dependency to check/fix "ros-pcl-conversions" so at the end, please test, and in case you agree with my analysis, reject proj and accept pcl ** Changed in: pcl (Ubuntu Artful) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.

Impact: unable to link libraries against pcl-dev without [hacky workaround](https://github.com/ros- perception/perception_pcl/commit/42683bd4069c3a8bcec56d6c4e686d9e8643e77b) Changelog introducing the bug: ``` vtk6 (6.3.0+dfsg1-3) unstable; urgency=medium * Rebuild against new multiarch enabled openmpi, Closes: #848785 ``` Solution: rebuild libpcl-dev against libvtk6-dev (6.3.0+dfsg1-3) Thanks!
