One of the toys I got this Christmas is the very nifty CMUCam3 . I haven't done much with it yet (the first picture I took with it is below). But, I did hit a small bump in the instructions for setting it up under Linux. The CMUCam3 Linux Quick Start Guide (overall, quite good) suggests downloading the Linux ARM-gcc compiler from the CMUCam downloads page. However, the link you'll find there has you download an installer binary instead of the bzip package referenced later in the instructions. In the CMUCam3 source directory, however, you'll find that BUILDING.txt provides a link to the CodeSourcery download page . From there you can find the bzip packaged version of the toolchain. I recommend that route instead. Update Be sure to download the EABI target OS version.
