按照此链接中提供的教程，我正在尝试将 ORB_SLAM 作为 ROS Indigo 中的 ROS 节点运行。执行 /.build_ros.sh 行后，我面临一系列错误，

/home/ubuntu_16/ORB_SLAM2/Examples/ROS/ORB_SLAM2/../../../Thirdparty/g2o/g2o/types/../core/jacobian_workspace.h:30:22: fatal error: Eigen/Core: No such file or directory
compilation terminated.
CMakeFiles/RGBD.dir/build.make:118: recipe for target 'CMakeFiles/RGBD.dir/src/ros_rgbd.cc.o' failed
make[2]: *** [CMakeFiles/RGBD.dir/src/ros_rgbd.cc.o] Error 1
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/RGBD.dir/all' failed
make[1]: *** [CMakeFiles/RGBD.dir/all] Error 2

我无法摆脱这些问题，如果有人遇到同样的问题，请帮助。谢谢你。

Do you install Eigen? Try this: sudo apt-get install libeigen3-dev
