1. 從https://github.com/opencv/opencv/releases 下載opencv源碼opencv-4.1.0.zip并解壓縮；

2. 修改最頂層的CMakeLists.txt，在第658行加入一條語句如下，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行語句，fix error: libopencv_imgcodecs.so.4.1.0: undefined reference to png_init_filter_functions_neon等錯(cuò)誤:

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

4. 腳本build.sh內(nèi)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根目錄下，依次執(zhí)行如下命令，執(zhí)行完后會(huì)將生成的頭文件和動(dòng)態(tài)庫(kù)存放在build/install目錄：

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

6.?將build/bin目錄下的example_tutorial_porting_anisotropic_image_segmentation_gapi及動(dòng)態(tài)庫(kù)拷貝到海思板子上，執(zhí)行，顯示結(jié)果一切正常，說明OpenCV編譯正常，執(zhí)行結(jié)果如下：

注意：

1.?由于海思板子不支持GTK，所以必須添加-DWITH_GTK=OFF項(xiàng)，所以在海思板子上不支持imshow相關(guān)函數(shù)；

2.?如想減少編譯時(shí)間，可不編譯examples，將-DINSTALL_C_EXAMPLES和-DBUILD_EXAMPLES由ON調(diào)整為OFF。
