    Installation hints

    4.9.1

    • build with intel/19.0.3, due to an compiler error full optimisation does not work
    • prerequisites: hdf5, netcdf, antlr, gsl, udunits2
    • passed through most checks, except expected failures. omp-related checks did not work - possibly due to missing omp environment. Since nco is mostly IO-limited, this should not matter. omp-capabilities are not tested yet.
    • install script
