wsl环境

1. 安装wsl

ubuntu版本必须为18.04。 windows打开powershell 输入以下命令，不要使用cmd

wsl --install -d Ubuntu-18.04

安装参考地址：https://learn.microsoft.com/zh-cn/windows/wsl/install

2.正常安装928的开发环境，参考指南。

3.修改目录

3.1 交叉编译工具

修改cmake/ss298.cmake目录交叉编译工具路径

SET(CMAKE_C_COMPILER   /opt/linux/x86-arm/aarch64-mix210-linux/bin/aarch64-mix210-linux-gcc)
SET(CMAKE_CXX_COMPILER /opt/linux/x86-arm/aarch64-mix210-linux/bin/aarch64-mix210-linux-g++)
SET(CMAKE_STRIP        /opt/linux/x86-arm/aarch64-mix210-linux/bin/aarch64-mix210-linux-strip)

3.2 修改CMakeLists.txt

把全部的/home/setups/ss928_framework/ 替换为自己wsl项目目录，比如/mnt/d/ss928_framework/

4. 把虚拟机中相关目录拷贝wsl中同样的目录下

需要复制的目录为

• /usr/local/lib
• /usr/local/local

注意！！！,  注意！！！,  注意！！！,
    _.--""--._
    .'          `.
   /   O      O   \
  |    \  ^^  /    |
  \     `----'     /
   `. _______ .'
     //_____\\
    (( ____ ))
     `------'  

复制粘贴- /usr/local/lib和/usr/local/local先打成压缩包，再解压到wsl目录中，直接从虚拟机中复制出来的时候会报错不支持符号链接的主机，无法复制。

压缩并保持符号链接

cd /usr/local/lib
zip -ry ~/lib.zip ./*

cd /usr/local/include
zip -ry ~/include.zip ./*

• -r 这个选项表示递归地处理目录
• -y 保持符合链接

自行放到wsl任意目录,cd进入该目录解压。如需强制覆盖，加上-o参数

sudo unzip lib.zip -d /usr/local/lib/
sudo unzip include.zip -d /usr/local/include/

把板子上相关目录拷贝wsl中同样的目录下

需要复制到目录为

• /lib/aarch64-linux-gnu
• /usr/lib/aarch64-linux-gnu

cd /lib/aarch64-linux-gnu
zip -ry ~/lib_agnu.zip ./*

cd /usr/lib/aarch64-linux-gnu
zip -ry ~/usr_lib_agnu.zip ./*

自行放到wsl任意目录,cd进入该目录解压。如需强制覆盖，加上-o参数

sudo unzip lib_agnu.zip -d /lib/aarch64-linux-gnu/
sudo unzip usr_lib_agnu.zip -d /usr/lib/aarch64-linux-gnu/

cmake3.24版本

下载地址：https://cmake.org/files/v3.24/cmake-3.24.0-linux-aarch64.tar.gz 解压后的bin目录为可执行文件，自行放到目录中。

5.编译

mkdir build
cd build
cmake ..
make -j(nproc)

build/libss928driver.so为生成的动态库文件

执行

上传

• ss928sdk/lib 拷贝到 板端目录下
• 将生成的动态库文件build/libss928driver.so拷贝到板端目录下
• 将om模型文件拷贝到板端目录下
• 自己要测试的图片，以及下面所属的python脚本

你最终的目录结构应该是这样的

_test_928_batch.py   #脚本
best_sea_salt.om # 模型文件
lib/ # 库文件
libss928driver.so # 编译的动态库
ymj_sea_salt/   # 测试图片目录
ymj_sea_salt_result/ #结果图片目录

设置环境

# 设置环境变量能读取到lib的动态库
export LD_LIBRARY_PATH=${PWD}/lib:${PWD}/lib/npu:${PWD}/lib/svp_npu:$LD_LIBRARY_PATH
# fix ymj runtime oserror /usr/lib/aarch64-linux-gnu/libgomp.so.1: cannot allocate memory in static TLS block
export LD_PRELOAD=/usr/lib/aarch64-linux-gnu/libgomp.so.1:$LD_PRELOAD

创建conda环境

• 将下面内容复制保存为environment.yaml,
• 然后在板端执行conda env create -f environment.yaml
• 创建完毕之后，激活环境conda activate ymj。
