The error occurs with __fOptions__ CRAN package which appears to carry a copy of your code.

|     Hi Dirk,
| 
|     Thanks to point this out.
| 
|     HQNORM is not declared as a double precision function in HALTON and might
|     be implicitly declared as single precision.
| 
|     I will upload a patch later today and see if it works.

|     Yohan
