Creating a new package

Create a new package

```bash
cd ~/code/code_idealab_ros/src/
catkin_create_pkg thorlabs_linear_actuator std_msgs rospy roscpp
cd ~/code/code_idealab_ros/
catkin_make
```

1. Find package dependencies:

   # one level
   rospack depends1 thorlabs_linear_actuator
   #all levels
   rospack depends thorlabs_linear_actuator
   

2. Open up package manifest:

   cd ~/code/code_idealab_ros/src/thorlabs_linear_actuator/
   gedit package.xml
   

3. Add description, clean up and remove comments. It should look like this when done

   <?xml version="1.0"?>
   <package format="2">
   
     <name>thorlabs_linear_actuator</name>
     <version>0.0.1</version>
     <description>The thorlabs_linear_actuator package</description>

     </export>
   
   </package>
   

4. Make

   cd ~/code/code_idealab_ros/
   catkin_make -DPYTHON_EXECUTABLE=/usr/bin/python3
   #catkin_make install  # (optionally)
   
   # make one thing
   #catkin_make --source my_src
   #catkin_make install --source my_src  # (optionally)
