Antonio,

Here is the hunk of code where this is failing.  You might try compiling
this into a test program on your system to see why the C routine
"sscanf" is failing?  Could it be some internationalization issue with
your linux system?

-- Jon

static float JC_String_ConvertLongitudeToFloat( char *string )
{
     float value=0;
     int n=0;
     char tempText[256]="";

     if ( (n = sscanf(string, "%f%s", &value, tempText)) != 2 ) {
          fprintf(stderr, "ERROR in JC_Utility.c:
JC_String_ConvertLongitudeToFloat(): sscan
f read %d items.\n", n);
          return 1;
     }
 ...
}
