WRF Hydro Coupled fails to build without specific paths added

When building WRF Hydro Coupled following the NCAR's build guide located here:


It fails to build with intel llvm compilers.

Steps to reproduce:

  1. Install the required libraries
  2. download the wrf-hydro 5.4 github (git clone GitHub - NCAR/wrf_hydro_nwm_public: WRF-Hydro model code)
  3. download WRF 4.7.1 in new folder ( git clone GitHub - wrf-model/WRF: The official repository for the Weather Research and Forecasting (WRF) model -> cd WRF -> git submodule update --init --recursive )
  4. remove hydro folder from wrf folder based on users guide and then copy WRF hydro src folder to new hydro folder ( rm -r
    Code: 
    "${WRF_FOLDER}"/WRF-${WRF_VERSION}/hydro/cp -r "${WRF_FOLDER}"/Hydro-Basecode/wrf_hydro_nwm_public/src "${WRF_FOLDER}"/WRF-${WRF_VERSION}/hydro
  5. configure ( ./configure_new -x -p "oneAPI LLVM" -- -DWRF_CORE=ARW -DWRF_NESTING=BASIC -DWRF_CASE=EM_REAL -DUSE_MPI=ON -DUSE_PIO=ON -DENABLE_HYDRO=ON -DWRF_HYDRO_NUDGING=1 -DUSE_HDF5=${HDF5_ROOT} -DUSE_JASPER=${Jasper_ROOT} 2>&1 | tee wrf_configure_new.log)
  6. compile ( ./compile_new -j 2 2>&1 | tee compile.wrf1.log)
  7. Build will fail at fftpack5


Now this is what I don't understand, when I export the netcdf include and lib paths the compilation will build.

Code: 
export FFLAGS="-I${NETCDF_ROOT}/include ${FFLAGS}"
  export FCFLAGS="-I${NETCDF_ROOT}/include ${FCFLAGS}"
  export LDFLAGS="-L${NETCDF_ROOT}/lib    ${LDFLAGS}"

why is this?

@islas any ideas why the include and lib paths aren't being added to the cmake commands?

Yes. The hydro/ folder is also designed to be able to build without replacing it with the hydro repo's own, so it should be standalone
That's from @islas and according to the hydro people the hydro folder that's in WRF's tar file is built and maintained by the WRF staff not them. So i'm confused who to ask my questions to.

I just want to make sure i am asking in the proper forum
