Hello everyone,

I am working on Groovy and have all the libraries installed.

I have created a custom .msg file with following entries :

Header header

pcl_msgs/PolygonMesh mesh

sensor_msgs/PointCloud2 normals

I have included pcl_msgs in my package.xml and CMakelists.txt also.

But unfortunately on compilation I get following errors

-- checking for module 'openni-dev'
--   package 'openni-dev' not found
-- Could NOT find openni (missing:  OPENNI_INCLUDE_DIRS) 
** WARNING ** io features related to openni will be disabled

pcl_msgs )

catkin_package(

include_directories(

${PCL_INCLUDE_DIRS}

${catkin_INCLUDE_DIRS} )

link_directories(${PCL_LIBRARY_DIRS})

add_definitions(${PCL_DEFINITIONS})

I have looked through pcl forums but not able to resolve this problem. Any kind of guidance would be much appreciated. Thanks

It looks like the pcl_msgs that are released into Groovy are in the pcl namespace; try declaring your message dependency on pcl instead of pcl_msgs.

Thanks a lot ahendrix, exactly this was the issue. I checked in the documentaion of pcl 1.6, they are using the namespace pcl, for e.g. pcl::PolygonMesh , so using the namespace "pcl" worked. Here is the link : http://docs.pointclouds.org/1.6.0/search.php?query=polygonmesh

It looks like you don't have the pcl_msgs package installed, or it isn't on your cmake path.

Try installing it with:

sudo apt-get install ros-groovy-pcl-msgs

Thanks for your response ahendrix, but it still doesn't compile. is there some specific change required in the package.xml and CMakelists.txt ? ( I have included build and runtime dependencies for "pcl_msgs" in package.xml and corresponding dependencies in CMakelists.txt as well )

It's possible that you're still missing a dependency somewhere in your CMakeLists.txt. Can you add your CMakeLists.txt to your question?

So, I also compared "pcl_msgs" directory of hydro and groovy. Hydro has "pcl_msgs-msg-paths.cmake" but groovy version doesn't.
