2:在将之前配置的soc-sdk拷贝一份到sdk根目录，将交叉编译好的sail中的build_soc拷贝至soc-sdk文件夹内；

cp -rf build_soc/sophon-sail/inlcude soc-sdk

cp -rf build_soc/sophon-sail/lib soc-sdk

3:安装交叉编译器

 sudo apt-get install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu

4：新建文件夹MNIST，目录结构如下

CMakeFile.txt

set(CMAKE_C_COMPILER aarch64-linux-gnu-gcc)set(CMAKE_ASM_COMPILER aarch64-linux-gnu-gcc)set(CMAKE_CXX_COMPILER aarch64-linux-gnu-g++)include_directories("/home/wzw/Bitmain/Release_230301-public/soc-sdk/include")include_directories("/home/wzw/Bitmain/Release_230301-public/soc-sdk/include/sail")# 添加交叉编译需要使用的头文件目录link_directories("//home/wzw/Bitmain/Release_230301-public/soc-sdk/lib")# 添加交叉编译需要使用的动态库目录set(SOURCE_FILES main.cpp)set(TARGET_NAME MNIST)add_executable(${TARGET_NAME} ${SOURCE_FILES})target_link_libraries(${TARGET_NAME} sail)# sail为需要链接的库

 

main.cpp

#define USE_FFMPEG 1#define USE_OPENCV 1#define USE_BMCV 1#include <stdio.h>#include <sail/cvwrapper.h>#include <iostream>#include <string>using namespace std;int main(){int device_id = 0;std::string video_path = "test.avi";sail::Decoder decoder(video_path,true,device_id);if(!decoder.is_opened()){printf("Video[%s] read failed!\n",video_path.c_str());exit(1) ;}sail::Handle handle(device_id);sail::Bmcv bmcv(handle);while(true){sail::BMImage ost_image = decoder.read(handle);bmcv.imwrite("test.jpg", ost_image);break;}return 0;}

 

5：编译cmake CMakeFile.txt

make

6：拷贝至板端

scp MNIST linaro@10.12.13.112:/home/wzw

./MNIST
