Hi all,

I went through many posts and found that by adding target_link_libraries the error which looks like following, stops.

CMakeFiles/visual_par.dir/src/visual_par.cpp.o: In function `main':
visual_par.cpp:(.text+0x55): undefined reference to `ros::init(int&, char**, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int)'

Invoking "make" failed

However I am still getting the error.

CMakefile:

cmake_minimum_required(VERSION 2.8.3)
project(visual_par)

find_package(catkin REQUIRED COMPONENTS roscpp visualization_msgs)

catkin_package(
#  INCLUDE_DIRS include
  CATKIN_DEPENDS roscpp visualization_msgs
)

  ${catkin_INCLUDE_DIRS}
)

add_executable(visual_par src/visual_par.cpp)
target_link_libraries(visual_par ${catkin_LIBRARIES})

I am trying to run following tutorial on visual markers:

#include <ros/ros.h>
#include <visualization_msgs/Marker.h>

#include <cmath>

int main( int argc, char** argv )
{
  ros::init(argc, argv, "visual_par");
  ros::NodeHandle n;
  ros::Publisher marker_pub = n.advertise<visualization_msgs::Marker>("visualization_marker", 10);

  ros::Rate r(30);

  float f = 0.0;
  while (ros::ok())
  {

    visualization_msgs::Marker points, line_strip, line_list;
    points.header.frame_id = line_strip.header.frame_id = line_list.header.frame_id = "/my_frame";
    points.header.stamp = line_strip.header.stamp = line_list.header.stamp = ros::Time::now();
    points.ns = line_strip.ns = line_list.ns = "points_and_lines";
    points.action = line_strip.action = line_list.action = visualization_msgs::Marker::ADD;
    points.pose.orientation.w = line_strip.pose.orientation.w = line_list.pose.orientation.w = 1.0;



    points.id = 0;
    line_strip.id = 1;
    line_list.id = 2;

    points.type = visualization_msgs::Marker::POINTS;
    line_strip.type = visualization_msgs::Marker::LINE_STRIP;
    line_list.type = visualization_msgs::Marker::LINE_LIST;

    // POINTS markers use x and y scale for width/height respectively
    points.scale.x = 0.2;
    points.scale.y = 0.2;

    // LINE_STRIP/LINE_LIST markers use only the x component of scale, for the line width
    line_strip.scale.x = 0.1;
    line_list.scale.x = 0.1;



    // Points are green
    points.color.g = 1.0f;
    points.color.a = 1.0;

    // Line strip is blue
    line_strip.color.b = 1.0;
    line_strip.color.a = 1.0;

    // Line list is red
    line_list.color.r = 1.0;
    line_list.color.a ...
