They had it working for Linux and Windows but it seems to have been abandoned about 2011. As written it uses sysfs, which even Linux abandoned, I haven't looked at what they used it for exactly. It's looking for /usr/include/sysfs/libsysfs.h which I don't have even on my Raspberry Pi, the only Linux box I've got.
