交叉编译工具
1.创建文件夹
#输入
mkdir toolchain
mkdir toolchain/gcc-linaro
cd toolchain/gcc-linaro
2.下载交叉编译工具
#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
3.解压
#输入
tar -xf gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz
4.创建交叉编译工具配置脚本
#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
5.执行加权限
#输入
chmod +x gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.sh
6.配置交叉编译环境
#输入
source ~/toolchain/gcc-linaro/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.sh
7.检查安装
#输入
${CROSS_COMPILE}gcc -v
#输出
Using built-in specs.
