Hi all, I`m trying to use Eclipse with Catkin. I`m having some problems with Index, for example, I have just tried to do this tutorial: http://www.ros.org/wiki/pcl/Tutorials and Eclipse doesn`t recognizes the index to "sensor_msgs::PointCloud2" (all these type). I`m able to compile the package into Eclipse(CTRL+B), it is working fine, my problem is with the Eclipse indexer. My steps to make Eclipse "works" on catkin were: $cd ~/catkin_ws $catkin_make --force-cmake -G"Eclipse CDT4 - Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_ECLIPSE_MAKE_ARGUMENTS=-j8  $source ~/catkin_ws/devel/setup.bash $eclipse File -> Import -> General -> Existing Projects into Workspace... When I open the .cpp file, I got some errors: Type 'sensor_msgs::PointCloud2' could not be resolved Type 'sensor_msgs::PointCloud2ConstPtr' could not be resolved ... But, how I said, I`m able to compile the package, I just have NOT the indexes for this type. Can you guys help me to make Eclipse index this? Thank you, Andre Barcelos.
