This is just some sample code for using the HPi module with the Melexis MLX90614 contact-less temperature sensor. You will need the C library for BCM 2835 to build the code.
To build this sample run the following:
$ cabal sandbox init $ cabal build # ./dist/build/MLXi2C/MLXi2C
There may be a way to run the program without root, but I haven't found it yet.
