Using these steps:


# Clone the WRF-Hydro repository and set up the build
git clone https://github.com/NCAR/wrf_hydro_nwm_public.git
cd wrf_hydro_nwm_public
mkdir -p build
cd build

# Run CMake configuration for WRF-Hydro with specified options
cmake .. \
-DSPATIAL_SOIL=1 \
-DWRF_HYDRO=1 \
-DWRF_HYDRO_NUDGING=1 \
-DWRFIO_NCD_LARGE_FILE_SUPPORT=1 \
-DCMAKE_Fortran_COMPILER=ifx

# Compile using specified CPU settings
make -j "$CPU_QUARTER_EVEN" 2>&1 | tee make.log


I get this output:

In the previous build there was a .exe for noahMP.  Did that get removed?

Hi Will,

Correct, it got removed in an April 30th commit this year. We removed wrf_hydro_NoahMP.exe when we also dropped the .exe. Dropping the .exe extension is more inline with WRF and something we've wanted to do for a while since .exe is specific to Windows Operating Systems. We are slowly transitioning, so right now the default option for WRF_HYDRO_CREATE_EXE_SYMLINK is ON and the wrf_hydro.exe is still being created. Part of the thinking is wrf_hydro and wrf_hydro_NoahMP have always been symlinked and pointing to each other so it's a bit redundant. We are trying to slowly clean that up and unify to a single executable.

Cheers,
Soren
