Package not found

[jacksakers]

I followed the video to create a ros package and named it homework3 and everything. Now when I try to run the node inside the package I am told that the homework3 package cannot be found. How do I make the package discoverable?

I have made it executable and even when I copy the homework2 package it says that it cannot be found as well. The only package that works is the homework2 package.

You have to run "catkin build" and source the setup.bash file for the package to be discoverable. Follow the instructions from homework 2 if needed.
