Re: OPeNDAP does not work on enabled NCL 6.1.0 precompiled binary for Mac OS 10.6

Hi Sean,

Maybe this is an issue with trying to open a GRIB file, because I just downloaded the 10.6 binary:

ncl_ncarg-6.1.0.MacOS_10.6_i386_64bit_gcc460.tar.gz

and was able to run this small script on it:

  filename = "http://test.opendap.org/opendap/data/nc/3fnoc.nc"
  if(.not.isfilepresent(filename)) then
    print("OPeNDAP isfilepresent test unsuccessful.")
    print("Either file doesn't exist, or NCL does not have OPeNDAP capabilities on this system")
    exit
  end if

  print("OPeNDAP isfilepresent test successful.")
  print("You will get some warnings here about the 'MissingToFillValue option set True...'")
  print("")
  f = addfile(filename,"r")
  print("variables = " + getfilevarnames(f))

However, I do have the same issue when it comes to trying to open your GRIB2 file, and I am able to open it using NCL V6.0.0

I have created a ticket for this, NCL-1577.

Meanwhile, regarding the "i386_64bit" file name: I know it's confusing, but the "i386" in this case is what that Mac reports, but the NCL binary was built with the 64-bit option set for the compiler, so it is still 64-bit.
