Todo:

If cross-compiling for ARM on older versions of Ubuntu, note the following files are not the same:

• /usr/include/linux/i2c-dev.h
• /usr/arm-linux-gnueabi/include/linux/i2c-dev.h

To get around this issue, I've copied a few of the necessary i2c_smbus_* functions from the newer file in /usr/include/linux/i2c-dev.h.
