Hello World Demo

First, let's do a quick test that will ensure the previous compilation step worked correctly. This rather boring program will only display the text Hello world! but if it works correctly then we know all the other demos should work too, and we can make more interesting programs run.

Enter the following commands to go inside the hello_world folder and list the files:

cd hello_world
ls

You’ll notice the .bin file is shown in green; this is because it is an executable file. This means that it is the file we run to launch the program.

Use the following command to run the demo. You need the ./ to specify the current directory; otherwise the Linux system folders will be searched for the filename you type.

./hello_world.bin
