[rosbuild] Building package ORB_SLAM-master
 [rosbuild] Error from directory check:  /opt/ros/kinetic/share/ros/core/rosbuild/bin/check_same_directories.py/home/windistance/program/ORB_SLAM2/Examples/ROS/ORB_SLAM2

 CMake Error at /opt/ros/kinetic/share/ros/core/rosbuild/private.cmake:102 (message):
 [rosbuild] rospack found package "ORB_SLAM2" at "", but the current
 directory is "/home/windistance/program/ORB_SLAM2/Examples/ROS/ORB_SLAM2". You should
 double-check your ROS_PACKAGE_PATH to ensure that packages are found in the
 correct precedence order.

• 解决方案为

  gedit ~/.bashrc
  

在.bashrc 末尾添加：

export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:/home/windistance/program/ORB_SLAM2/Examples/ROS/ORB_SLAM2

source ~/.bashrc

• 出错原因为：libboost_system.so 与libboost_filesystem.so找不到链接目录

• 解决方案为

  locate  boost_system //查找位置
  
  /usr/lib/x86_64-linux-gnu/libboost_system.a
  /usr/lib/x86_64-linux-gnu/libboost_system.so
  /usr/lib/x86_64-linux-gnu/libboost_system.so.1.58.0
  
  locate boost_filesystem //查找位置
  
  /usr/lib/x86_64-linux-gnu/libboost_filesystem.a
  /usr/lib/x86_64-linux-gnu/libboost_filesystem.so
  /usr/lib/x86_64-linux-gnu/libboost_filesystem.so.1.58.0
  
  
  

  将libboost_system.so与libboost_filesystem.so复制到ORB_SLAM2/lib下，并且将ORBSLAM2/Examples/ROS/ORBSLAM2下的Cmakelists.txt中加入库目录,或者直接把查找到的路径加到库目录

  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
  /usr/lib/x86_64-linux-gnu/libboost_system.so
  /usr/lib/x86_64-linux-gnu/libboost_filesystem.so
  )
  
  

  再次编译,问题解决:

• 出错原因为：找不到eigen

• 解决方案为

sudo cp -r /usr/local/include/eigen3 /usr/include

重新编译问题解决
