Revision history [back]

This is not a linker error, but a build error. The error tells you that it does not find a specific header file.

Afaik, pcl::toRosMsg is defined in the pcl_conversions package. Add this to the CMakeLists.txt, and include pcl_conversions.h in the file where you use the toRosMsg call.

Also, please clean the CMakeLists.txt up, before posting here ;-) i.e. remove all the commented parts. I'd also recomend to have all the stuff at the end in the respective calls where it belongs, e.g. uncomment the PCL part here:

target_link_libraries(player_node
  ${catkin_LIBRARIES}
  ${OpenCV_LIBRARIES}
  #${PCL_LIBRARIES} #ADDED BY MARTIN
)

instead of having this below again...
