Unifying netCDF/HDF versions across components

[russfiedler]

At the moment the various components appear to be built with different netCDF versions by default. There really should be a common version used. This is important in the light of problems with some of the libraries. See here for issues if we move to PIO for CICE. COSIMA/cice5#34

libcheck.sh provides overview of the libraries used

[russfiedler]

Yes it provides an overview and it's how I spotted all the different libraries being used. The thing is that, ideally, they should be consistent in the first place.

[aekiss]

I agree - it was just a FYI but you already knew...

libcheck.sh now reports netcdf/4.3.2 being used for all submodels.

Hi @nichannah I've encountered something weird - when I compile this latest version with install.sh, libcheck.sh gives me the wrong netcdf version

      /short/v45/aek156/sources/new/access-om2/src/libaccessom2/build/bin/yatm.exe:
	libnetcdff.so.6 => /apps/netcdf/4.4.1.1/lib/libnetcdff.so.6 (0x00007fe62dbae000)
	libnetcdf.so.11 => /apps/netcdf/4.4.1.1/lib/libnetcdf.so.11 (0x00007fe62a7db000)

This seems to be due to install.sh:

access-om2/install.sh

Line 39 in 21d92b5

module load netcdf/4.4.1.1

When I recompile with that line removed I get

      /short/v45/aek156/sources/new/access-om2/src/libaccessom2/build/bin/yatm.exe:
	libnetcdff.so.6 => not found
	libnetcdf.so.11 => not found

so for some reason it's not picking up module load netcdf/4.3.2 from build_on_raijin.sh.

install.sh uses cmake and make - does this even use build_on_raijin.sh?

[aekiss]

I've set install.sh to use build_on_raijin.sh in 488b084
but build_on_raijin.sh has an issue: COSIMA/libaccessom2#24

[nichannah]

Re our TWG discussion, do we now want to upgrade again to netcdf/4.7.1?

[nichannah]

Closing this for now, we can do upgrade as a separate issue.
