Re: OPeNDAP

Hi Mingxuan,

The file you indicated does not exist, because I've never built a binary for MacOS 10.8.

Can you please verify the correct file name so I can check it here?

I have verified that these three binaries are all working fine with regard to OPeNDAP:

  ncl_ncarg-6.1.0-beta.MacOS_10.6_i686_64bit_gcc460.tar.gz
  ncl_ncarg-6.1.0-beta.MacOS_10.7_i686_64bit_gcc450.tar.gz
  ncl_ncarg-6.1.0-beta.MacOS_10.7_x86_64_gcc421.tar.gz

This is the short NCL script I used to test this:

  url = "http://apdrc.soest.hawaii.edu:80/dods/public_data/ERA-40/"
  filename = "daily-surface"
 
  exists = isfilepresent(url+filename)
  if(.not.exists) then
    print("OPeNDAP isfilepresent test unsuccessful.")
    print("Either file doesn't exist, or NCL does not have OPeNDAP capabilities on this system")
    status_exit(1)
  else
    print("OPeNDAP isfilepresent test successful.")
    f = addfile(url + filename,"r")
    variables = getfilevarnames(f)
    print(variables)
  end if

--Mary
