编译安装WRF

操作步骤

1. 执行以下命令解压WRF安装包。

   tar -zxvf WRF-3.9.tar.gz

2. 执行以下命令进入WRF源码目录。

   cd WRF-3.9

3. 执行以下命令设置编译前环境。

   export WRFIO_NCD_LARGE_FILE_SUPPORT=1
   export NETCDF=/path/to/install/NETCDF
   export HDF5=/path/to/install/HDF5
   export PNETCDF=/path/to/install/PNETCDF
   export CPPFLAGS="-I$HDF5/include -I$PNETCDF/include -I$NETCDF/include"
   export LDFLAGS="-L$HDF5/lib -L$PNETCDF/lib -L$NETCDF/lib -lnetcdf -lnetcdff -lpnetcdf -lhdf5_hl -lhdf5 -lz"

4. 执行以下命令修改arch/configure_new.defaults文件。

   vim arch/configure_new.defaults

   在文件#insert new stanza here下面添加：

5. 执行以下命令生成配置文件。

   ./configure

   输入“4”，再按“enter”键。

   输入“1”，再按“enter”键。

6. 执行以下命令编译安装。

   ./compile em_real 2>&1 | tee -a compile.log

7. 执行以下命令验证是否安装成功。

   ls main

   回显生成了“wrf.exe”等可执行文件，表明编译成功。
