Hi, all

I'm testing "Creating a Custom shell".
I was processed the next content.

1> I was followed the content of "Creating a Custom shell"
 -. How to Customize the shell
 -. Setting up the source Files for a custom shell
 -. Creating an Empty Display-Based OS
 -. Setting up platform builder to build modified code in a public directory
 -. Creating Exclued projects to Host shell Source Code in the IDE
2> rebuild Platform.
 -. sounded like no error.
3> chose the my project and right-click my projcet and chose build.
    I wrote the compile message .

  Compiling...
