Compiles via make but the following error occurs:

I2C: Failed write to the device : Remote I/O error I2C: Failed to write to the device : Remote I/O error I2C: Failed to read in the value. : Remote I/O error Could not find a valid LSM303!

I double checked that the sensor was visible via i2cdetect.

I replaced the address defines copied from the Adafruit Arduino code with the actual address values. The defines were bit-shifting hardcoded values to get the addresses for the sensors. Also, ensure that the program is run with superuser permissions in order to access the I2C bus.
