Hey guys,

I'm attempting to run the pcl_visualizer_demo.cpp found here: http://pointclouds.org/documentation/...

I have taken the _demo off the .cpp file and in the CMakeLists.txt.

I ran:

 catkin_create_pkg pcl_visualizer roscpp std_msgs rospy

I then placed the pcl_visualizer.cpp in the catkin_ws/src/pcl_visualizer/src folder

this is my full CMakeLists.txt file, as specified by the tutorial linked above, with only the _demo removed from the appropriate places. (note that I still get the same error even with _demo being included and the package being named appropriately for that as well).

cmake_minimum_required(VERSION 2.6 FATAL_ERROR)

project(pcl_visualizer)

find_package(PCL 1.2 REQUIRED)

include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})

add_executable (pcl_visualizer pcl_visualizer.cpp)
target_link_libraries (pcl_visualizer ${PCL_LIBRARIES})

When I run the catkin_make, I get this error:

CMake Error: CMake can not determine linker language for target: pcl_visualizer
CMake Error: Cannot determine link language for target "pcl_visualizer".

Does anyone have any suggestions as to what could be causing this?
