「 Linux调试错误 」CMake Error at /opt/ros/kinetic/share/ros/core/rosbuild/public.cmake:129 (message):

一、问题描述

        在编译ORB_SLAM2中Example的ROS时，执行到

• $ chmod +x build_ros.sh

• $ ./build_ros.sh

时。报出如下错误：

CMake Error at /opt/ros/kinetic/share/ros/core/rosbuild/public.cmake:129 (message):Failed to invoke rospack to get compile flags for package 'ORB_SLAM2'.Look above for errors from rospack itself.  Aborting.  Please fix thebroken dependency!Call Stack (most recent call first):/opt/ros/kinetic/share/ros/core/rosbuild/public.cmake:207 (rosbuild_invoke_rospack)CMakeLists.txt:4 (rosbuild_init)-- Configuring incomplete, errors occurred!
See also "/home/tiddy/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/build/CMakeFiles/CMakeOutput.log".
make: *** No targets specified and no makefile found.  Stop.

二、错误原因

未找到，ROS_PACKAGE_PATH路径。

三、解决方法

        需要在环境变量中配置ROS_PACKAGE_PATH路径到当前的ROS安装目录下。

        （1）打开bashrc文件。

$cd ~
$vim .bashrc

        （2）在bashrc文件的最后一行加上下面代码：

export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:PATH/ORB_SLAM2/Examples/ROS#其中PATH是你的工作空间路径(/home/(user名)/catkin_ws/src)

        （3）然后在终端执行：

$source ~/.bashrc

        （4）再执行：

$sudo rosdep fix-permissions
$rosdep update

        问题解决。（详细的ORB_SLAM2编译过程，请看小白其它博客。）
