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

首先重现安装教程中 fortran/build_help 的源代码构建步骤，然后对列出的 .f90 文件运行报告中的 f2py 命令。检查有关 wrf_constants 和 omp_lib 的结果消息，并比较建议的 -I、-L、numpy.f2py 和 f2py3 方法。完成的标准是确定受支持的构建路径，并解决报告的 f2py 错误或将其清楚地记录下来。

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
