1. 从[https://github.com/opencv/opencv/releases][https_github.com_opencv_opencv_releases] 下载opencv源码opencv-4.1.0.zip并解压缩；

2. 修改最顶层的CMakeLists.txt，在第658行加入一条语句如下，fix error: pngstruct.h:30:18: fatal error: zlib.h: No such file or directory \#include "zlib.h":

ocv_include_directories(./3rdparty/zlib)

3. 修改3rdparty/libpng/CMakeLists.txt，在文件前加入以下4行语句，fix error: libopencv\_imgcodecs.so.4.1.0: undefined reference to png\_init\_filter\_functions\_neon等错误:

IF(HISI3559A)
    	SET(ARM 1)
    	SET(ENABLE_NEON 1)
    ENDIF()

4. 脚本build.sh内容如下：

cmake \
    	-DCMAKE_BUILD_TYPE=RELEASE \
    	-DCMAKE_C_COMPILER=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-gcc \
    	-DCMAKE_CXX_COMPILER=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-g++ \
    	-DBUILD_SHARED_LIBS=ON \
    	-DCMAKE_CXX_FLAGS=-fPIC \
    	-DCMAKE_C_FLAGS=-fPIC \
    	-DCMAKE_EXE_LINKER_FLAGS=-lpthread -lrt -ldl \
    	-DENABLE_PIC=ON \
    	-DWITH_1394=OFF \
    	-DWITH_ARAVIS=OFF \
    	-DWITH_ARITH_DEC=ON \
    	-DWITH_ARITH_ENC=ON \
    	-DWITH_CLP=OFF \
    	-DWITH_CUBLAS=OFF \
    	-DWITH_CUDA=OFF \
    	-DWITH_CUFFT=OFF \
    	-DWITH_FFMPEG=ON \
    	-DWITH_GSTREAMER=ON \
    	-DWITH_GSTREAMER_0_10=OFF \
    	-DWITH_HALIDE=OFF \
    	-DWITH_HPX=OFF \
    	-DWITH_IMGCODEC_HDR=ON \
    	-DWITH_IMGCODEC_PXM=ON \
    	-DWITH_IMGCODEC_SUNRASTER=ON \
    	-DWITH_INF_ENGINE=OFF \
    	-DWITH_IPP=OFF \
    	-DWITH_ITT=OFF \
    	-DWITH_JASPER=ON \
    	-DWITH_JPEG=ON \
    	-DHISI3559A=1 \
    	-DWITH_PNG=ON \
    	-DWITH_LAPACK=ON \
    	-DWITH_LIBREALSENSE=OFF \
    	-DWITH_NVCUVID=OFF \
    	-DWITH_OPENCL=OFF \
    	-DWITH_OPENCLAMDBLAS=OFF \
    	-DWITH_OPENCLAMDFFT=OFF \
    	-DWITH_OPENCL_SVM=OFF \
    	-DWITH_OPENEXR=OFF \
    	-DWITH_OPENGL=OFF \
    	-DWITH_OPENMP=OFF \
    	-DWITH_OPENNNI=OFF \
    	-DWITH_OPENNNI2=OFF \
    	-DWITH_OPENVX=OFF \
    	-DWITH_PROTOBUF=OFF \
    	-DWITH_PTHREADS_PF=ON \
    	-DWITH_PVAPI=OFF \
    	-DWITH_QT=OFF \
    	-DWITH_QUIRC=OFF \
    	-DWITH_TBB=OFF \
    	-DWITH_TIFF=ON \
    	-DWITH_VULKAN=OFF \
    	-DWITH_WEBP=ON \
    	-DWITH_XIMEA=OFF \
    	-DWITH_GTK=OFF \
    	-DINSTALL_C_EXAMPLES=ON \
    	-DINSTALL_PYTHON_EXAMPLES=OFF \
    	-DBUILD_EXAMPLES=ON \
    	-DCMAKE_INSTALL_PREFIX=./install \
    	..

5. OpenCV根目录下，依次执行如下命令，执行完后会将生成的头文件和动态库存放在build/install目录：

mkdir build
    cd build
    cp ../build.sh .
    ./builld.sh
    make -j8
    make install

6. 将build/bin目录下的example\_tutorial\_porting\_anisotropic\_image\_segmentation\_gapi及动态库拷贝到海思板子上，执行，显示结果一切正常，说明OpenCV编译正常，执行结果如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ZlbmdiaW5nY2h1bg_size_16_color_FFFFFF_t_70][]

注意：

1. 由于海思板子不支持GTK，所以必须添加-DWITH\_GTK=OFF项，所以在海思板子上不支持imshow相关函数；

2. 如想减少编译时间，可不编译examples，将-DINSTALL\_C\_EXAMPLES和-DBUILD\_EXAMPLES由ON调整为OFF。
