From source code building, an error occurred while executing the "f2py".

1. I did not report any errors when executing the following code in the installation tutorial：
   cd ./fortran/build_help
   gfortran -o sizes -fopenmp omp_sizes.f90
   python sub_sizes.py
   cd ..
   gfortran -E ompgen.F90 -fopenmp -cpp -o omp.f90
2. when i excute " f2py *.f90 -m _wrffortran -h wrffortran.pyf --overwrite-signature " , these are errors

3. The method I am trying to use
   Add this Fortran folder through - I or - L. Use Python - m numpy.f2py. Using f2py3

Start by reproducing the source-build steps in the installation tutorial from fortran/build_help, then run the reported f2py command over the listed .f90 files. Review the resulting messages about wrf_constants and omp_lib and compare the suggested -I, -L, numpy.f2py, and f2py3 approaches. Done means the supported build path is identified and the reported f2py errors are resolved or clearly documented.
