Hi all,

I have a linker issue while using tf library. Here is my callback. Without this only line in the callback there is NO linker error. Please, find below the linker error itself.

void callback (const sensor_msgs::PointCloud2ConstPtr& input)
{
  listener->waitForTransform("/world_base_link", (*input).header.frame_id, (*input).header.stamp, ros::Duration(5.0));
 ...
}

int main (int argc, char** argv)
{
  ros::init(argc, argv, "subscriber");
  ros::NodeHandle n;
  ros::Subscriber sub = n.subscribe("/kinect2/depth/points", 1, callback);
  ros::spin ();
}

Linker error:

Linking CXX executable range_image_border_extraction
CMakeFiles/range_image_border_extraction.dir/range_image_border_extraction.cpp.o: In function `callback(boost::shared_ptr<sensor_msgs::PointCloud2_<std::allocator<void> > const> const&)':

CMakeLists.txt

cmake_minimum_required(VERSION 2.6 FATAL_ERROR)

project(range_image_border_extraction)

find_package(PCL 1.7 REQUIRED)
find_package(catkin REQUIRED COMPONENTS roscpp rospy std_msgs genmsg tf pcl_ros)

include_directories(${PCL_INCLUDE_DIRS})

target_link_libraries(range_image_border_extraction ${PCL_LIBRARIES})
target_link_libraries(range_image_border_extraction ${catkin_LIBRARIES})

Any ideas how to resolve this linker error?

Adding tf to find_package in CMakeLists.txt solved the problem. I had:

find_package(catkin REQUIRED COMPONENTS roscpp rospy std_msgs genmsg)

Should be:

find_package(catkin REQUIRED COMPONENTS roscpp rospy std_msgs genmsg tf)

catkin_package() is required: http://wiki.ros.org/catkin/CMakeLists...

Put catkin_package(CATKIN_DEPENDS roscpp rospy std_msgs genmsg tf pcl_ros) after find_package()
