2.7. Expanding Variables

Sometimes it is helpful to determine what a variable expands to during a build. You can do examine the values of variables by examining the output of the bitbake -e command. The output is long and is more easily managed in a text file, which allows for easy searches:

     $ bitbake -e virtual/kernel > some_text_file
            

Within the text file, you can see exactly how each variable is expanded and used by the OpenEmbedded build system.
