c++ - 未定义的引用错误对我没有任何意义

我在这里有此代码:
Main.cpp

#include "AStarPlanner.h"
#include <costmap_2d/costmap_2d.h>

int main(int argc, char** argv)
{
   AStarPlanner planner =  AStarPlanner(10,10,&costmap);
}

和我的类(class):
AStarPlanner.h

class AStarPlanner {

public:

  AStarPlanner(int width, int height, const costmap_2d::Costmap2D* costmap);
  virtual ~AStarPlanner();

AStarPlanner.cpp

#include "AStarPlanner.h"

using namespace std;

AStarPlanner::AStarPlanner(int width, int height, const costmap_2d::Costmap2D* costmap)
{

  ROS_INFO("Planner Konstruktor");
  width_ = width;
  height_ = height;
  costmap_ = costmap;
}

我看不到我有任何错误。该函数已定义，并且我的main.cpp知道该类。

CMakeList

cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)

rosbuild_init()

#set the default path for built executables to the "bin" directory
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
#set the default path for built libraries to the "lib" directory
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)

rosbuild_add_library (robot_mover src/AStarPlanner.cpp )
rosbuild_add_executable(robot_mover src/main.cpp)

但是我得到这个错误:
未定义对vtable for AStarPlanner'**** undefined reference to的引用AStarPlanner::〜AStarPlanner()'

最佳答案

您未能为AStarPlanner定义析构函数。您可以这样将其添加到AStarPlanner.cpp中:

AStarPlanner::~AStarPlanner()
{
}

考虑this advice。
