交叉编译工具链安装指导
- 进入arm-gnu-toolchain-downloads，根据操作系统的架构，选择相应的软件包版本。
- 对于x86环境，建议安装arm-gnu-toolchain-14.2.rel1-x86_64-aarch64-none-elf.tar.xz
- 对于arm环境，建议安装arm-gnu-toolchain-14.2.rel1-aarch64-aarch64-none-elf.tar.xz。
不同操作系统的安装步骤一致，本节以x86环境的软件包为例进行说明。x86环境下载工具链包并解压至本地环境。
tar -xvf arm-gnu-toolchain-14.2.rel1-x86_64-aarch64-none-elf.tar.xz
- 执行以下命令，将解压后目录中的bin文件夹内的文件软链接至usr/bin目录下。
ln -sf {本地下载的包路径}/arm-gnu-toolchain-14.2.rel1-x86_64-aarch64-none-elf/bin/* /usr/bin/例如：
ln -sf /root/arm-gnu-toolchain/bin/* /usr/bin/
- 输入下面命令，查看是否软链接成功。
ll /usr/bin |grep aarch64-none-elf
打印信息如下所示，即安装成功。
