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

Comienza reproduciendo los pasos de compilación del código fuente del tutorial de instalación en fortran/build_help y, después, ejecuta el comando f2py indicado sobre los archivos .f90 enumerados. Revisa los mensajes resultantes sobre wrf_constants y omp_lib y compara los enfoques sugeridos con -I, -L, numpy.f2py y f2py3. Se considera terminado cuando se haya identificado la ruta de compilación compatible y los errores de f2py indicados se hayan resuelto o documentado claramente.

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
