操作步骤

使用PuTTY工具，以root用户登录服务器。
执行以下命令创建并且进入NEMO安装目录。
```
mkdir -p /path/to/NEMO
cd /path/to/NEMO
```

执行以下命令配置NEMO编译需要的环境变量。

echo "export NETCDF_DIR=/path/to/NETCDF" >> nemo-env.sh
echo "export HDF_DIR=/path/to/HDF5" >> nemo-env.sh
echo "export XIOS_DIR=/path/to/XIOS/xios-1.0" >> nemo-env.sh
source nemo-env.sh

执行以下命令解压安装包。

unzip NEMO_releases_release-3.6-10083.zip

执行以下命令进入NEMO源码目录。
```
cd NEMO/releases/release-3.6/NEMOGCM
```

执行以下命令创建文件“arch-aarch64_gnu.fcm”。

创建文件“arch-aarch64_gnu.fcm”。
```
vi ARCH/arch-aarch64_gnu.fcm
```

按“i”进入编辑模式，添加如下内容。

%CFLAGS              -O0

行尾和空行不能有空格。

按“Esc”键，输入:wq!，按“Enter”保存并退出编辑。

执行以下命令编译安装软件。

chmod 777 ./ -R
cd ./CONFIG/
./makenemo -m aarch64_gnu -j 32 -r AMM12 -n 'MY_AMM12' add_key "key_nosignedzero"

编译和安装
