建立catkin_ws工作空間出現catkin_make錯誤解決方法

錯誤代碼：

The specified base path “/home/ubuntu/catkin_ws” contains a CMakeLists.txt but “catkin_make” must be invoked in the root of workspace…..

出現這種情況的原因是catkin_init_workspacce的時候，出現下面這句：

Creating symlink “/home/ubuntu/catkin_ws/CMakeLists.txt” pointing to “/opt/ros/indigo/share/catkin/cmake/toplevel.cmake”

将目前工作空間下的CMakeLists.txt與/ros/下的cmake做了連結

解決方法：

unlink /home/ubuntu/catkin_ws/CMakeLists.txt
