## 交叉编译工具 


1.创建文件夹
<pre>#输入
    mkdir toolchain
    mkdir toolchain/gcc-linaro
    cd toolchain/gcc-linaro</pre>
2.下载交叉编译工具
<pre>#输入
    wget https://releases.linaro.org/components/toolchain/binaries/7.5-2019.12/aarch64-linux-gnu/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz</pre>
3.解压
<pre>#输入
    tar -xf gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz</pre>
4.创建交叉编译工具配置脚本
<pre>#输入
    cat << EOF > ~/toolchain/gcc-linaro/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.sh
    #!/bin/sh
    export PATH=${HOME}/toolchain/gcc-linaro/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin:${PATH}
    export ARCH=arm64
    export CROSS_COMPILE=aarch64-linux-gnu-
    EOF</pre>
5.添加可执行权限
<pre>#输入
    chmod +x gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.sh</pre>
6.配置交叉编译环境
<pre>#输入
    source ~/toolchain/gcc-linaro/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.sh </pre>
7.检查安装
<pre>#输入
    ${CROSS_COMPILE}gcc -v
#输出
   Using built-in specs.
