SimpleIDE error issue?

I have been trying to learn c and modifying the examples.
I get this error and I have been trying to solve this for hours.
I need some help.

Thank you

ps- attached are the compilation error and zip file.


  • A couple of items here.

    First you don't need to copy all the libraries into this folder to use them unless they are some special libraries.
    SimpleIDE can reference them from the learn folder if need be.

    Attached is and update to your project that has the library referenced correctly. The library folder can be deleted in your project then.

    Also the error is because of the missing item on the while clause.

    Thanks for helping me.
    The project do compile however the robot only goes straight foreward and
    will not respond to the sony remote and will not play any sound
    and also does not respond to ping.

    Thanks for your help


  • While I do not have your setup so debugging the code is difficult.

    Once you enter your second while loop it will loop there forever and wait for you to press a button (2, 3, or 4) and play a wave file that is indicated.
