Re: [netcdfgroup] [Support #WCM-111191]: Problem reading version 3.x 64 bit offset files with ncdump in netcdf-4.0-beta1

Hi Russ,

I'm sorry, I have to apologize. I have now discovered that what I thought was installed as the NetCDF4 version of ncdump must actually be an HDF4 version. The real NetCDF4 version works just fine on this file. I was sure I had installed it to my /usr/local/bin directory but apparently not, or perhaps it was overwritten.

So excuse me while I wipe the egg off my face. I hope you didn't spend too much time on this. Meanwhile thanks for pointing out the '-k' option which I had not been aware of.

Hi Dave,

I'm having trouble duplicating the error you are seeing. In particular, I can't seem to make ncdump from netCDF4 produce the message "ncopen failed" on any file, real or imaginary, and it works OK on 64-bit-offset files. Just to be sure, can you please send me output from the
following, using the netCDF4 ncdump

  ls -l
  ncdump -k
  ncdump -V

The last command will say "-V" is an illegal option, but will then print out the version number, which is what I want to see. Ans just to be sure I understand how the file was created, did you use the netCDF-4.0-beta1 library to create the 7.7Gbyte file, or did you use netCDF-3.6.2 and the
64BIT_OFFSET creation mode?
