步骤
1. 准备交叉编译环境
安装交叉编译器
sudo apt install gcc-aarch64-linux-gnu
# 验证是否安装成功
(base) jokeShineZhang:~/mindspore_deploy_demo_aarch64$ aarch64-linux-gnu-gcc --version
aarch64-linux-gnu-gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

# file: toolchain.cmake
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_PROCESSOR aarch64)
set(CMAKE_C_COMPILER aarch64-linux-gnu-gcc)2. 下载demo并交叉编译
下载

配置运行环境
将libmindspore-lite.so和libmindspore_glog.so.0拷贝至/usr/local/lib # 编辑~/.bashrc 增加环境变量
vim ~/.bashrc# ~/.bashrc 末尾增加以下内容后保存
export LD_LIBRARY_PATH/usr/local/lib:$LD_LIBRARY_PATH# 重新加载当前用户的 ~/.bashrc 配置文件
source ~/.bashrc# 检验动态库是否加载成功
