PIO 2.5.4 and NetCDF-4.8.1 (HDF5-1.12.1)

[rjdave]

I have not tried auto-tools, but cmake (v3.19.1) configure fails with NetCDF-4.8.1 because NC_DISPATCH_VERSION has changed from 2 to 3 in the latest release. I changed line 369 in CMakeLists.txt to:

#if !(NC_DISPATCH_VERSION == 2 || NC_DISPATCH_VERSION == 3)

and configure completed and make, make tests completed but I get 7 failed tests with ctest:

The following tests FAILED:
         43 - pio_file_fail (Timeout)
        104 - tst_async_multi (Failed)
        105 - tst_ncint_async_perf (Failed)
        106 - tst_ncint_perf (Failed)
        107 - tst_pio_async (Failed)
        108 - tst_pio_udf (Failed)
        109 - tst_var_compress (Failed)

I found this pull request and this issue about NC_DISPATCH_VERSION so I'm betting you already know some changes (possibly to src/ncint/ncintdispatch.{c&h}) are probably necessary to account for the switch from filter_actions to filter_ids and filter_info. Unfortunately, I don't know nearly enough about filters or dispatch tables to help much.

@edwardhartnett Can you help with this issue?

[edwardhartnett]

Try building PIO without the --enable-netcdf-integration and see if that works...

@edwardhartnett that does work, the issue is supporting the NC_DISPATCH_VERSION=3

[jedwards4b]

@edwardhartnett I would like to make a new PIO tag - any chance we can make NC_DISPATCH_VERSION=3
work before I do that? Thanks.

[edwardhartnett]

Sorry, I didn't have time and may not until the next release of netcdf-c, in which the dispatch table will change again.

What I am doing is working on new compression in netCDF, and this will also require some new functions in PIO to use these capabilities...
