As a result, they cannot be uploaded into -proposed at the same time. vtk6 must happen first, and pcl only once vtk6 has been built. [Test Case] * apt install libvtk6-dev libpcl-dev * git clone https://github.com/kyrofa/pcl-sru-test.git * cd pcl-sru-test * cmake . * make * You'll first note that it fails to build because it needs libproj- dev installed. Apply the first patch (to vtk) in this SRU, rebuild and install that version of vtk. * Build again, and you'll note that it fails to link to vtkproj4. This is the libproj that was vendored by vtk, but should not be used at all in Xenial (it's actually building against the system libproj). This is fixed by the second patch (to pcl) in this SRU, a no-change rebuild that causes the cmake config to be regenerated to properly link to the system libproj instead of the vtk-vendored libproj. Rebuild and install that version of pcl. * Finally, the build should succeed. [Where problems could occur] * This patch doesn't change ABI or API, but does add a dependency * Problems could potentially occur if clients worked around this issue by hacking their projects to link to vtkproj, but known users (ROS) have vendored Debian's fix into their repos as opposed to working around the bug, thus regressions seem unlikely To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcl/+bug/1573234/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~group.of.nepali.translators Post to : group.of.nepali.translators@lists.launchpad.net Unsubscribe : https://launchpad.net/~group.of.nepali.translators More help : https://help.launchpad.net/ListHelp
