CDO

Hi Win!

you seem to use spack for installing the dependencies of CDO. There is a spack for CDO itself, so manual installation from the source is not really needed.

I use the 'develop' branch of spack, last commit from 2019-08-25. try

spack info cdo

btw: Ubuntu comes with a cdo package. It's an older revision, but might still fit your needs.

Hi Ralf,
Thanks a lot for your reply. So I tried this:

win@win-desktop:~$ spack compiler find
> Found no new compilers
> Compilers are defined in the following files:
/home/win/.spack/linux/compilers.yaml
win@win-desktop:~$ spack install cdo
==> Error: An unsatisfiable variant constraint has been detected for spec:

^zlib@1.2.11%gcc@7.4.0+optimize+pic+shared arch=linux-ubuntu18.04-x86_64

while trying to concretize the partial spec:

netcdf requires hdf5 variant +hl, but spec asked for ~hl

How the error message looks on screen is in the attached file.
Can you suggest how to fix this issue?
regards,
win

I just installed CDO from linux package by doing sudo apt install cdo
I got version 1.9.3 and I guess it should work for my purpose. So I'm good for now.

alright - good to know, Win.

I will start chasing this spack-issue then

cheers
ralf

should be

 spack install cdo '^hdf5+hl'

OK, full speck without lengthy openmpi installation (which is not needed at all)

spack spec -I cdo '^hdf5+hl~mpi' '^netcdf~mpi' '^fftw~mpi'
