tap5.0 rosluanch错误

我尝试着一个一个Tag运行，看看每一次的优化。 在git clone 5.0版本，并catkin_make后，roslaunch front_end.launch后，报告process has died。我不太清楚是哪里的问题，因为我并没有对代码做任何的修改。完整的信息如下：

hurricanezj-Alienware-17-R4:~/catkin_ws$ roslaunch lidar_localization front_end.launch ... logging to /home/hurricanezj/.ros/log/99c924c4-88fd-11ea-91e7-9cb6d0effb2d/roslaunch-ZhaoJie-Alienware-17-R4-25122.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

SUMMARY ========

PARAMETERS * /rosdistro: kinetic * /rosversion: 1.12.14

ROS_MASTER_URI=http://localhost:11311

希望您可以抽空帮我看看。运行环境为Ubuntu16.04，ros-kinetic ，前面的tag3.0与tag4.0均正常。

    我查询了一些资料，并用GDB来查看，可能的原因指向了：对空指针进行了操作。

    这种提示信息没有直接给出报错的位置，一般我遇到这种问题，都是在程序里加打印信息来定位出错位置在哪，找到位置，原因就很好分析了。 另外，你每次下载一个新的tag，重新编译的时候，有没有把之前的devel和build删掉

    我发现cmake的时候有两条报错被我忽略了，与vtk和saveMap_gencpp有关。全文如下： -- ==> add_subdirectory(catkin_hdl_slam/src/hdl_graph_slam) -- Using these message generators: gencpp;geneus;genlisp;gennodejs;genpy -- Boost version: 1.58.0 -- Found the following Boost libraries: -- system -- filesystem -- thread -- date_time -- iostreams -- serialization -- chrono -- atomic -- regex WARNING io features related to pcap will be disabled WARNING io features related to png will be disabled -- The imported target "vtkRenderingPythonTkWidgets" references the file "/usr/lib/x86_64-linux-gnu/libvtkRenderingPythonTkWidgets.so" but this file does not exist.

    通过加注释，定位到问题出在front_end_node.cpp中的: _front_end_flow_ptr = std::make_shared(nh);

    程序里是这句，你是程序变了，还是这个回答里写错了 _front_end_flow_ptr = std::make_shared(nh);

    如果还没解决，你就在知乎上私信我吧，github我上的少

    _front_end_flow_ptr = std::make_shared<FrontEndFlow>(nh);
