2 Create ROS Package

In catkin_ws src folder,

catkin_create_pkg [name] [dependencies]

for dependencies, it can be rospy or roscpp

Then the folder named [name] is created, with CMakeLists.txt package.xml src files are created.

roscd [name]

this brings you to ROS package that you have just created.

If this does not work, you need to go to catkin_ws and

source devel/setup.bash

To compile everything in src forder, you need to go to catkin_ws and type

catkin_make
