1. 下载opencv4.6.0并解压

https://opencv.org/releases/

unzip opencv-4.6.0.zip

cd opencv-4.6.0

2. 安装基础工具

sudo apt-get install build-essential

sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

3. 在opencv-4.6.0/目录下编写编译脚本

vim build.sh

#!/bin/bash
set -e # Exit immediately if a command exits with a non-zero status.

BuildDir=/home/ydf/work/src/001/opencv/opencv-4.6.0/build
ToolChain=/opt/hisi-linux/x86-arm/arm-himix200-linux

if [ ! -d "$BuildDir" ]; then
  # Take action if $BuildDir doesnât exists. 
  echo "create ${BuildDir}..."
  mkdir -p ${BuildDir}
fi
cd ${BuildDir}

echo "building OpenCV4"

cmake -D CMAKE_BUILD_TYPE=RELEASE \
      -D BUILD_SHARED_LIBS=OFF \
      -D CMAKE_FIND_ROOT_PATH=${ToolChain}/ \
      -D CMAKE_TOOLCHAIN_FILE=../platforms/linux/arm-gnueabi.toolchain.cmake \
      -D CMAKE_C_COMPILER=${ToolChain}/bin/arm-himix200-linux-gcc \
      -D CMAKE_CXX_COMPILER=${ToolChain}/bin/arm-himix200-linux-g++ \
      -D CMAKE_C_FLAGS="-mfloat-abi=softfp -mfpu=neon" \
      -D CMAKE_CXX_FLAGS="-mfloat-abi=softfp -mfpu=neon" \
      -D CMAKE_INSTALL_PREFIX=${BuildDir}/install \
      -D WITH_TBB=ON \
      -D WITH_EIGEN=ON \
      -D BUILD_ZLIB=ON \
      -D BUILD_TIFF=ON \
      -D BUILD_JASPER=ON \
      -D BUILD_JPEG=ON \
      -D BUILD_PNG=ON \
      -D ENABLE_NEON=ON \
      -D ENABLE_VFPV3=ON \
      -D WITH_LIBV4L=ON \
      -D BUILD_opencv_python=OFF \
      -D ENABLE_PRECOMPILED_HEADERS=OFF \
      -D BUILD_EXAMPLES=OFF \
      -D BUILD_TESTS=OFF \
      -D BUILD_PERF_TESTS=OFF \
      -D BUILD_WITH_DEBUG_INFO=OFF \
      -D BUILD_DOCS=OFF \
      -D WITH_OPENCL=OFF \
      -D WITH_1394=OFF \
      ..

make -j$(nproc)

4. 编译opencv

sh build.sh

5. 编写测试程序

vim test.cpp

#include <stdio.h>
#include <opencv2/opencv.hpp>

using namespace cv;

int main(int argc, char** argv)
{
    if ( argc != 2 ) {
        printf("usage: test.out <image_Path>\n");
        return -1;
    }
    
    Mat image = imread(argv[1]);
    if (image.empty()) {
        printf("Reading image fails.\n");
        return -1;
    }

    Mat gray;
    cvtColor(image, gray, COLOR_BGR2GRAY);
    imwrite("gray.jpg", gray);
    printf("Writing gray image success.\n");

    return 0;
}

6. 编写cmake文件

vim CMakeLists.txt

# 设置目标工程名称
project(TEST)

# 设置生成文件名称
set(TARGET test)

# 设置编译最小版本
cmake_minimum_required(VERSION 3.12)

# 设置目标平台系统
set(CMAKE_SYSTEM_NAME Linux)

# 设置交叉编译路径
set(CMAKE_FIND_ROOT_PATH /opt/hisi-linux/x86-arm/arm-himix200-linux/bin)

# 设置交叉编译工具
set(CMAKE_C_COMPILER arm-himix200-linux-gcc)
set(CMAKE_CXX_COMPILER arm-himix200-linux-g++)
set(CMAKE_C_EXTENSIONS "")
set(CMAKE_CXX_EXTENSIONS "")

# 设置库的目录路径
set(OpenCV_DIR /home/ydf/work/src/001/opencv/opencv-4.6.0/build)
find_package(OpenCV REQUIRED)
message(STATUS "OpenCV library status:")
message(STATUS "    version: ${OpenCV_VERSION}")
message(STATUS "    libraries: ${OpenCV_LIBS}")
message(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")

# 添加编译文件目录
aux_source_directory(${PROJECT_SOURCE_DIR} USRSRC)

# 添加生成执行文件
add_executable(${TARGET} ${USRSRC})

# 执行生成文件链接
TARGET_LINK_LIBRARIES(${TARGET} ${OpenCV_LIBS})

7.编译测试文件
rm -rf build && mkdir build && cd build && cmake .. && make

7. 编译测试文件

rm -rf build && mkdir build && cd build && cmake .. && make

8. 拷贝生成文件到开发版，如果出现symbol _ZNSt15__exception_ptr13exception_ptrC1Ev, version CXXABI_1.3.11 not defined in file libstdc++.so.6 with link time reference问题，请使用/opt/hisi-linux/x86-arm/arm-himix200-linux/arm-linux-gnueabi/lib/libstdc++.so.6.0.23复制到板子上/lib进行替换，可能开发板自带的libstdc++.so.6.0.23存在问题。
