ROS Base path和Source space不一致问题，修改文件名后无法make问题,catkin_make报错问题

在一次在ROS 的学习实践中，将Ros工程目录名称更改了，source后，出现了base path和Source space不一致问题：

报错提示：

Base path: /home/pot/catkin_ws_top
Source space: /home/pot/catkin_ws_top/src

The specified base path "/home/pot/catkin_ws_top" contains a CMakeLists.txt but "catkin_make" must be invoked in the root of workspace

图示： 

  

修改方法：

将工作目录下的CMakeLists.txt删除，重新catkin_make一下，会提示：

CMake Error: The current CMakeCache.txt directory /home/pot/catkin_ws/build/CMakeCache.txt is different than the directory /home/pot/catkin_ws_top/build where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you are not sure, reedit the CMakeCache.txt

提示当前的编译路径和已经存在的CMakeCache.txt不匹配问题

图示：

解决办法，删除工作目录下build的全部文件重新catkin_make

编译通过

图示

如还有其它问题请自行检查CMakeListis.txt文件以及环境配置是否有问题
