Hi all, I have successfully rosmaked the Correpsondence Grouping Tutorial(a tutorial in PCL), and now I want to send a message to a topic if I recognized the target in correspondence grouping. However, the correspondence grouping tutorial doesn't use any thing about ros before, so I wonder to know how to emerge ROS in this tutorial. I tried to add the code like the tutorial: WritingPublisherSubscriber(c++)(http ://www.ros.org/wiki/ROS/Tutorials/WritingPublisherSubscriber%28c%2B%2B%29), and modified my cmakelist, but I always get the error:
CMakeFiles/correspondence_grouping.dir/correspondence_grouping.cpp.o: In function main': correspondence_grouping.cpp:(.text+0xa1f): undefined reference toros::Publisher::~Publisher()' correspondence_grouping.cpp:(.text+0x1de6): undefined reference to ros::console::g_initialized' correspondence_grouping.cpp:(.text+0x1df5): undefined reference toros::console::initialize()'

So, does anyone knows how to solve this?

I think it would be easier to help you if you show your code. Are you sure you added the required includes ? #include "ros/ros.h"

Also show the CMakeLists.txt. It looks like you are not building for ROS.
