New Debian issues after merging ROS 1 stuff

[jlblancoc]

• Build in i386 is broken due to failing unit tests, apparently in the conversion of gridmap values between ROS and MRPT maps: log

[ RUN      ] Map.check_ros2mrpt_and_back
/<<PKGBUILDDIR>>/libs/ros1bridge/src/map_unittest.cpp:92: Failure
The difference between 1.0f - 0.01f * i and desMrpt.getCell(i, 0) is 0.99964302935404703, which exceeds 0.03f, where
1.0f - 0.01f * i evaluates to 1,
desMrpt.getCell(i, 0) evaluates to 0.00035697064595296979, and

After a quick inspection, I didn't see any obvious source of this problem... postponing. (Anyone?)

• Xenial packages are broken due to a bug in vtk6 / PCL packaging. See:
  Link error: cannot find vtkproj4 PointCloudLibrary/pcl#1594 (comment)
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=819741

Our error is: log

/usr/bin/ld: cannot find -lvtkproj4

(vtkproj4 is not a real lib, but something internal to vtk)

@jolting : Didn't you have a VTK PPA for Xenial with a more modern version of vtk? I could add it as a PPA dependency to MRPT2 PPA.

PS: Good news is... mrpt-ros1bridge and the app rosbag2rawlog are already available from the PPA, and will be available from the official Ubuntu repos when mrpt 2 gets released 🎉

VTK and PCL need to be rebuilt
Fetch your PCL and VTK packages from my backport PPA.
sudo add-apt-repository -y ppa:jolting/backport-mrpt

Brilliant, thanks! Added to the PPA and build retried, let's see...

Build in i386 ...

might be fixed after 95ea836 . Let's keep an eye on PPA builds to check whether this one can be closed...
