Hi,
I added #include <ros/console.h> in the header files on top of my .cpp, but I still get this error :
undefined reference to `ros::console::initializeLogLocation()'
What shall I add in CMakeLists.txt, in catkin_package, or in package.xml? I use ROS Hydro.
Thanks
Thanks gvdhoorn
The missing dependencies were in the CMakeLists.txt In the turtlebot_arm_block_manipulation/CMakeLists, two scripts are commented and not compiled to executables, with a "TODO" mention. I uncommented the declaration without adding the target_link_libraries(..) and add_dependencies(...) that are needed. It was like that :
# TODO need review
# add_executable(block_manipulation test/block_manipulation.cpp)
# add_executable(block_manipulation_actions test/block_manipulation_actions.cpp)
Should be like that :
add_executable(block_manipulation test/block_manipulation.cpp src/cear_move_gripper.cpp)
target_link_libraries(block_manipulation ${catkin_LIBRARIES} ${PCL_LIBRARIES})
add_dependencies(block_manipulation turtlebot_arm_block_manipulation_gencpp)
add_executable(block_manipulation_actions test/block_manipulation_actions.cpp src/cear_move_gripper.cpp)
target_link_libraries(block_manipulation_actions ${catkin_LIBRARIES} ${PCL_LIBRARIES})
add_dependencies(block_manipulation_actions turtlebot_arm_block_manipulation_gencpp)
Note that "src/cear_move_gripper.cpp" is a node I implemented to action the gripper.
tl;dr: find_package(..) calls do not accumulate results, but overwrite. You are calling find_package(catkin ..) twice, and only the results of the second invocation end up in catkin_INCLUDE_DIRS & friends. So info on roscpp (and std_mgs) is not actually stored.
find_package(catkin REQUIRED COMPONENTS roscpp std_msgs) find_package(catkin REQUIRED actionlib actionlib_msgs interactive_markers pcl_ros roscpp visualization_msgs arbotix_msgs moveit_core moveit_ros_planning_interface genmsgs)
Your problem is actually a CMake issue: you ask CMake to find_package(..) something called catkin twice.
First with COMPONENTS set to roscpp std_msgs, and then another time with a whole new list of things for CMake to look for (using the catkin find script (or configure file)).
That doesn't work, as CMake will store the result of the first find_package(catkin ..) in variables prefixed with catkin_..., and then the result of the second find_package(catkin ..) in variables prefixed with catkin_... But you already had variables prefixed with catkin_.., so the first ones are actually overwritten (and the results for roscpp std_msgs are lost).
In order to fix this, just append the list after COMPONENTS from your second find_package(..) call to the first.
Edit: also:
link_directories(${catkin_LIBRARY_DIRS} ${Boost_LIBRARY_DIRS} ${PCL_LIBRARY_DIRS})
This is almost never necessary in a (properly setup) catkin/CMake project. All entries in (catkin, Boost, PCL)_LIBRARIES are supposed to be absolute paths. Explicitly calling link_directories(..) can actually cause strange library resolving errors.
Well, your CMakeLists.txt is incomplete: it doesn't contain any add_executable(..) or target_link_libraries(..) statements. Are you sure you are linking your nodes against catkin_LIBRARIES for instance? See Executable_Targets.

Please include your current
