So in 2024 Intel annouced that they will be removing the intel compilers ifort/icc/icpc with new intel llvm compilers ifx/icx/icpx and associated mpi compilers.

As it stands with WRF-Hydro 5.2 there is no configuration set up for these new intel llvm compilers.

I have tried to create one from scratch using the existing intel compilers as a guide and the llvm tutorials.

I request that NCAR look at these and see if they are correct and can implemented them into the main branch of 5.2 or with 5.3 release.

As it stands right now anyone who downloads the new intel compilers cannot get the classic compiler without paying for it.

Is this being worked on Kevin?

Maybe for the next release of 5.3 or wrf 4.6?

The legacy WRF-Hydro build system (using ./configure and ./compile_*) is being deprecated in favor of our new CMake-based build system, so no effort will be made to support new compilers with those older scripts. We are looking at the new Intel compilers, the Arm Fortran compiler, and AMD's AOCC Fortran compiler compatibility in the future, but these are low priorities for us and may not be supported until version 5.4 or later.

Where can I find instructions for the CMAKE build?

Will CMAKE support LLVM compilers by intel?

Will there be new instructions on the website and github on how to build with CMAKE?
