I have just found my Teensy 2 board and wanna build the laser ball but when I try and download the Teensyduino software I am coming up with a google error.

Anyone able to either point me in the direction of the software or have a copy that they can mail me.

Make sure youre downloading from a legitimate source:

core.a(main.cpp.o): In function `main':
C:\Users\WIPER\Desktop\arduino-1.0-rc2\hardware\teensy\cores\teensy/main.cpp:6: undefined reference to `setup'
C:\Users\WIPER\Desktop\arduino-1.0-rc2\hardware\teensy\cores\teensy/main.cpp:8: undefined reference to `loop'
That is the error I am coming up with any help pls know I am a newbie following a tutorial.

You appear to be using 1.0 release candidate 2 (i.e a pre-final version of an older release). The current version is 1.0.2 which you can get here
First install that, then download and install Teensyduino 1.10 from the link given by Magnethead494. Teensyduino modifieds the stock Arduino install to add Teensy 2.0 and Teensy ++ 2.0 support.

I downloaded the example to see what you were working with, and it's seems that you simply didn't load the program into the teensydunio sketch. Thoes two "built-in" functions are defined in the example. This is a bit new to me since I've always used make files and WinAVR to build programs for a Teensy 2.0. But I did download the the IRremote library from here (read the documentation in the code, this library is not included in the example):


Created a new folder under the libraries directory for it; and this complied just fine. Whether or not it works, that's a whole 'nother story (I can live without knowing.. :)). But this complied with no issues under the Teensydunio BETA release 8 that Paul has released for the Teensy3. I had it set up for the Teensy 2.0 board under tools, 16mhz.
