Creating a CollisionObject from a mesh in indigo

edit

im building a c++ code to move ur5_moveit_config on rviz, andvtrying to add a mesh into rviz with a ur5_moveit_config on it. i read some previous answers and use them to build my code. i believe my problem is at my code:

moveit_msgs::CollisionObject toilet;
shapes::Mesh* m = shapes::createMeshFromResource("package://home/toilet seat grubcad/toiletseat2.stl");
shape_msgs::Mesh toilet_mesh;
shapes::ShapeMsg toilet_mesh_msg;
shapes::constructMsgFromShape(m,toilet_mesh_msg);
toilet_mesh = boost::get<shape_msgs::Mesh>(toilet_mesh_msg);
toilet.meshes.resize(1);
toilet.meshes[0] = toilet_mesh;
toilet.mesh_poses.resize(1);
toilet.mesh_poses[0].position.x = 1.0;
toilet.mesh_poses[0].position.y = 1.0;
toilet.mesh_poses[0].position.z = 0.0;
toilet.mesh_poses[0].orientation.w= 1.0;
toilet.mesh_poses[0].orientation.x= 0.0;
toilet.mesh_poses[0].orientation.y= 0.0;
toilet.mesh_poses[0].orientation.z= 0.0;
//pub_co.publish(toilet);

toilet.meshes.push_back(toilet_mesh);
toilet.mesh_poses.push_back(toilet.mesh_poses[0]);
toilet.operation = toilet.ADD;

std::vector<moveit_msgs::CollisionObject> collision_objects;  
collision_objects.push_back(toilet);  

// Now, let's add the collision object into the world
ROS_INFO("Add an object into the world");  
planning_scene_interface.addCollisionObjects(collision_objects);

when i'm trying to "catkin_make" the program i get:
