无法找到lib

• 报错信息

• 解决方案 在Examples/ROS/ORB_SLAM2/CMakeLists.txt文件中添加编译信息-lboost_systema

	set(LIBS 
  	${OpenCV_LIBS} 
  	${EIGEN3_LIBS}
  	${Pangolin_LIBRARIES}
  	${PROJECT_SOURCE_DIR}/../../../Thirdparty/DBoW2/lib/libDBoW2.so
  	${PROJECT_SOURCE_DIR}/../../../Thirdparty/g2o/lib/libg2o.so
  	${PROJECT_SOURCE_DIR}/../../../lib/libORB_SLAM2.so
  	-lboost_systema ## 添加这一项
  )

无法找到ros package 或者ros

• 测试方式

      echo $ROS_ROOT
        /opt/ros/melodic/share/ros
      echo $ROS_PACKAGE_PATH
        /opt/ros/melodic/share:/home/test/slam/ORB_SLAM2-master/Examples/ROS/ORB_SLAM2
  

• 解决方案

  用户目录的.bashrc中添加

  # 有顺序要求 添加ros_root path
  source /opt/ros/melodic/setup.bash  
  # 添加ros_package_path
  export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:/home/test/slam/ORB_SLAM2-master/Examples/ROS/ORB_SLAM2
  

  应用添加的环境变量 source ~/.bashrc

编译pongoline出错

    cmake -DCPP11_NO_BOOST=1 ..
    make -j1
    Then,
    cd ORB_SLAM2
    chmod +x build.sh
