准备

• M1 CPU 的 Mac
• Sanp7的协议
• qt 5.12.9源代码

操作步骤

• 安装 Brew

# 第一个brew 
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"


#第二个
arch -arm64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# 配置代理和环境变量
alias proxy='export all_proxy=socks5://127.0.0.1:1089'
alias unproxy='unset all_proxy'
export PATH="/opt/homebrew/bin:/usr/local/bin:$PATH"
alias ibrew='arch -x86_64 /usr/local/bin/brew'

ibrew 安装 gettext

ibrew install gettext

解压

• 配置 arm编译工具
• 下载 https://github.com/thinkski/osx-arm-linux-toolchains/releases/download/8.3.0/arm-unknown-linux-gnueabihf.tar.xz
• https://thinkski.github.io/osx-arm-linux-toolchains/
• 解压到 /Users/用户名/Desktop/home/arm-unknown-linux-gnueabihf/

# 配置环境变量
export PATH=$PATH:/Users/用户名/Desktop/home/arm-unknown-linux-gnueabihf/bin

• 下载 qt-everywhere-src-5.12.9.tar.xz 安装

最后一步

• 将程序放到arm板子内

# 复制arm-qt的整个目录到`目标板`    /usr/lib/
# 复制 编译好的libsnap7.so 到`目标板`  /usr/lib/

export QT_ROOT=/usr/lib/arm-qt
export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event2

./ArmTools 这个就是 arm的二进制文件

good job。
