Yo David!

I looked at your program again.

You do not need these four lines:

    /* from <gps_json.h> */
    #define GPS_JSON_RESPONSE_MAX   4096

    char gpsdMessage[GPS_JSON_RESPONSE_MAX];
    size_t gpsdMessageLen = 0;

And you never use gpsdMessage, so just lose it.

Change this:

    if (gps_read (&gpsdata, gpsdMessage, gpsdMessageLen) == -1) {

To this:

    if (gps_read(&gpsdata, NULL, 0) == -1) {
