Re: installing opendap ncl 5.1.0 on Mac OS X

Hi Mary,

Thanks for your prompt reply. I believe I have those libraries
installed. I think the issue is that the path to libnc-dap.3.dylib
seems to be hardcoded in the ncl binary. When I created a directory /
Users/haley/tmp/5.1.0/lib/ on my system and placed a soft link to /opt/
local/lib/libnc-dap.3.dylib in that directory, ncl+opendap worked like
a charm (see below).

ncl 7> url = "http://test.opendap.org/opendap/data/nc/"
ncl 8> filename = "123.nc"
ncl 9> exists = isfilepresent(url+filename)
ncl 10> f = addfile(url + filename,"r")
ncl 11> vars = getfilevarnames(f)
ncl 12> print(vars)
