gfortran 编译netcdf出现的问题

gfortran nc.f90 -I/mnt/f/longbow/Build_WRF/LIBRARIES/netcdf/include -L/mnt/f/longbow/Build_WRF/LIBRARIES/netcdf/lib -lnetcdf -o nc.exe >& 1.out

出现的错误信息为：

问题解决了，查了半天资料，什么原因还是不了解。最后成功的编译方式如下：

gfortran -o nc.exe nc.f90 //mnt/f/longbow/Build_WRF/LIBRARIES/netcdf/lib/libnetcdff.a //mnt/f/longbow/Build_WRF/LIBRARIES/netcdf/lib/libnetcdf.a -I//mnt/f/longbow/Build_WRF/LIBRARIES/netcdf/include
