[LocutusOfBorg via ubuntu-bugs]

I'm sorry I couldn't fix the issue, lets think about bionic, because
fixing xenial will probably make the package not ABI safe anymore :/

The version of pcl in the proposed pocket of Xenial that was purported
to fix this bug report has been removed because the bugs that were to be
fixed by the upload were not verified in a timely (105 days) fashion.

This bug was fixed in the package pcl - 1.8.0+dfsg1-4ubuntu4.17.04.1

---
pcl (1.8.0+dfsg1-4ubuntu4.17.04.1) zesty; urgency=medium

  * No change rebuild for new vtk6 multiarchified openmpi.
This fixes the build failures due to cmake trying

The xenial version of the upload FTBFS on all architectures [1]. Could
someone take a look at the build logs and follow up with a fix? I have
released the zesty version in the meantime as that one was fine.

[Bug 1704459] Re: rebuild needed because dependency changed location of exported libmpi.so library

[LocutusOfBorg]

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

src:proj needs a rebuild too in xenial to be useful for its reverse-

[Bug 1704459] Re: rebuild needed because dependency changed location of exported libmpi.so library

[Timo Aaltonen]

Hello Mikael, or anyone else affected,

Accepted pcl into xenial-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/pcl/1.7.2-14ubuntu1.16.04.1 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  Source of the bug: last build of vtk6 exports libmpi.so in
  /usr/lib/x86_64-linux-gnu/openmpi/lib and not /usr/lib/openmpi/lib
  anymore.
  
  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!

There appears to be a new pcl in artful-proposed which might fix this,
but it failed to build on amd64 and arm64. The amd64 build failed due to
virtual memory exhaustion.
