That means we don't have a copy of the file Gmt_map.c here, and don't know the GMT definitions of the constants M_PI_2 or M_PI_4. You'll have to consult the GMT sources or direct GMT-related questions such as this one to the GMT mailing list or developers. See http://www.soest.hawaii.edu/soest/gmt.html for access to more GMT information. --Russ _____________________________________________________________________ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu
