• 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
