Adding Packages from the host

Description: Build a package file on the host, then install it on the Galileo.

Tutorial Level: INTERMEDIATE

Next Tutorial: Adding your own code


This tutorial will create a package file on the host, transfer it to the Galileo card, and install it there. This assumes you already have a ~/catkin_ws workspace set up as per the beginner tutorials.

Create the package

Create the package on the host machine:

$ source ~/catkin_ws/devel/setup.bash
$ cd ~/catkin_ws/src
$ catkin_create_pkg clanton_tutorial std_msgs rospy
$ cd ~/catkin_ws
$ catkin_make
$ cd -
$ mkdir scripts
$ cd scripts
$ wget https://raw.github.com/ros/ros_tutorials/groovy-devel/rospy_tutorials/001_talker_listener/talker.py
$ wget https://raw.github.com/ros/ros_tutorials/groovy-devel/rospy_tutorials/001_talker_listener/listener.py
$ chmod +x *.py
$ cd ..

Edit CMakeLists

Edit CMakeLists.txt, find the install section, and make sure the install clause looks like this:



$ cd ~/catkin_ws
$ catkin_make

Try it out on the host to make sure it works. In one window:

source ~/catkin_ws/install/setup.bash

In another window:

source ~/catkin_ws/install/setup.bash
rosrun clanton_tutorial talker.py

In another window:

source ~/catkin_ws/install/setup.bash
rosrun clanton_tutorial listener.py

If everything is working right, you should see "I heard hello world" in the last window. Now kill them all.

== Make the package ==

$ cd ~/devel_gal/meta-clanton_v0.7.5/meta-ros/recipes-ros
$ mkdir clanton-tutorial
$ cd clanton-tutorial
$ cp -r ~/catkin_ws/src/clanton_tutorial .

Edit a new file called "clanton-tutorial.bb" and make it look like this:

SRC_URI = "file:///home/jfstepha/catkin_ws/src/clanton_tutorial"
SECTION = "devel"

LIC_FILES_CHKSUM = "file:///home/jfstepha/foobar/lic.txt;md5=d440307f45f8d0776b0ce3be6de70d48"
DEPENDS = "catkin rospy std-msgs"
RDEPENDS = "rospy std-msgs"

S = "${WORKDIR}/clanton_tutorial"
inherit pkgconfig catkin
ROS_SPN = "ros_foobar"

FILES_${PN} += "/usr/share/clanton_tutorial/package.xml"
FILES_${PN} += "/usr/share/clanton_tutorial/cmake/clanton_tutorialConfig.cmake"
FILES_${PN} += "/usr/share/clanton_tutorial/cmake/clanton_tutorialConfig-version.cmake"

do_fetch () {
   cp -r /home/jfstepha/catkin_ws/src/clanton_tutorial ${WORKDIR}
