Upgrade on ubuntu results in cmake error - no sdformat-9.5

[Joshua]

Ran sudo apt upgrade/update on ubuntu noetic.

Now have the following cmake error:

CMake Error at /opt/ros/noetic/share/velodyne_gazebo_plugins/cmake/velodyne_gazebo_pluginsConfig.cmake:113 (message):
  Project 'velodyne_gazebo_plugins' specifies '/usr/include/sdformat-9.5' as
  an include dir, which is not found.  It does neither exist as an absolute
  directory nor in '${{prefix}}//usr/include/sdformat-9.5'.  Check the issue
  tracker 'https://bitbucket.org/dataspeedinc/velodyne_simulator/issues' and
  consider creating a ticket if the problem has not been reported yet.
Call Stack (most recent call first):
  /opt/ros/noetic/share/catkin/cmake/catkinConfig.cmake:76 (find_package)
  CMakeLists.txt:6 (find_package)

Have tried clean build and reinstalling sdformat9 to no avail.

The current latest sdformat is 9.7 rather than 9.5 - if I use a symbolic link from sudo ln -s /usr/include/sdformat-9.7 /usr/include/sdformat-9.5 I no longer receive the error and the package runs correctly.

I had a similar problem last week after a Gazebo update, but it was a compile error not a cmake configure error. The solution was to recreate the workspace (delete build and devel directories). A clean was not enough. Does that help?

[Kevin Hallenbeck]

It looks like velodyne_gazebo_plugins exports Gazebo’s include paths so dependent packages can find the includes, and the paths have changed since then due to a Gazebo and SDF update.

I can re-trigger a build in the buildfarm, but it won’t get out until the next sync.

Does your package need to find_package(catkin REQUIRED velodyne_gazebo_plugins) in its CMakeLists.txt? If not, you could remove it there and keep the dependency in package.xml.

It didn’t seem to fix the problem by deleting the build and devel dirs.

I think your right - I don’t think it’s needed in the CMakeLists.txt.

When is the next sync (ish)? It’s probably fine to wait for now.

They sync every 3-4 weeks:
