源码编译opencv卡在IPPICV: Download: ippicv_2017u3_lnx_intel64_general_20170822.tgz解决办法
ippicv 是一个并行计算库，安装过程中下载的时间很长，甚至下载失败。
以 ippicv_2017u3_lnx_intel64_general_20170822.tgz 为例，ippicv下载链接：ippicv
创建downloads下载路径：/PATH/TO/opencv-4.1.0/3rdparty/ippicv/downloads。
下载后，在下载目录创建脚本文件download_ippicv.sh：
#!/bin/bash
# 根据实际情况修改路径
ipp_file=./ippicv_2017u3_lnx_intel64_general_20170822.tgz &&
ipp_hash=$(md5sum $ipp_file | cut -d" " -f1) &&
ipp_dir=/PATH/TO/opencv-4.1.0/3rdparty/ippicv/downloads/linux-$ipp_hash && mkdir -p $ipp_dir &&
cp $ipp_file $ipp_dir
执行脚本：
chmod +x download_ippicv.sh
mkdir downloads
./download_ippicv.sh
修改 /PATH/TO/opencv-4.1.0/3rdparty/ippicv/ippicv.cmake：
"https://raw.githubusercontent.com/opencv/opencv_3rdparty/${IPPICV_COMMIT}/ippicv/"
修改为
"file:///media/sda3/360Downloads/opencv-4.10.0/3rdparty/ippicv/downloads/linux-0f2745ff705ecae31176dad437608f6f/"
face_landmark_model.dat手动下载 face_landmark_model.dat，下载路径为：/PATH/TO/cmake_files。
修改 /PATH/TO/opencv-4.1.0/opencv_contrib-4.1.0/modules/face/CMakeLists.txt：
"https://raw.githubusercontent.com/opencv/opencv_3rdparty/${__commit_hash}/"
修改为
"file:///PATH/TO/cmake_files/"
boostdesc_bgm.i 和 vgg_* 等文件下载路径： /PATH/TO/cmake_files。
下载 boostdesc_*：
boostdesc_bgm.i
boostdesc_bgm_bi.i
boostdesc_bgm_hd.i
boostdesc_binboost_064.i
boostdesc_binboost_128.i
boostdesc_binboost_256.i

参数解释：
CMAKE_INSTALL_PREFIX，指定opencv的安装路径。OPENCV_EXTRA_MODULES_PATH，指定opencv_contrib/modules的路径。该选项包含一个以分号分隔的目录列表，其中包含将添加到联编过程中的额外模块。CMAKE_BUILD_TYPE=RELEASE，表示编译发布版本。CUDA_ARCH_BIN=7.5，指定Compute Capability算力，对应的算力值需要根据自己的显卡型号到官网上查询。CUDA_FAST_MATH=ON，计算速度更快但是相对不精确。CUDA_NVCC_FLAGS="-std=c++11 --expt-relaxed-constexpr"，这句话是告诉cuda，也使用c++11来编译，否则会报错：“opencv cuda error: identifier “nullptr” is undefined”。WITH_CUDA=ON，使用CUDA，如果不是非常需要GPU或者没有CUDA，关掉这个就可以解决CUDA_nppi_LIBRARY的问题。WITH_CUBLAS=ON，与WITH_CUDA=ON 保持一致就好。WITH_GTK=ON，这个配置是为了防止GTK配置失败：即安装了libgtk2.0-dev依赖，还是报错未安装。WITH_QT=ON，如果qt未安装可以删去此行;若因为未正确安装qt导致的Qt5Gui报错，可将build内文件全部删除后重新cmake，具体可以参考这里。OPENCV_GENERATE_PKGCONFIG=YES，表示自动生成OpenCV的pkgconfig文件，否则需要自己手动生成。dynlink_nvcuvid.h 和 nvcuvid.h，所以要将 BUILD_opencv_cudacodec=OFF。如果编译 opencv-contrib 需要下载boost之类的可以不编译这个，则去掉 OPENCV_EXTRA_MODULES_PATH。Configure和Generate生成配置，请参考：【Ubuntu版】源码安装opencv（三）
1. start cmake-gui
2. select the opencv source code folder and the folder where binaries will be built (the 2 upper forms of the interface)
3. press the configure button. you will see all the opencv build parameters in the central interface
4. browse the parameters and look for the form called OPENCV_EXTRA_MODULES_PATH (use the search form to focus rapidly on it)
5. complete this OPENCV_EXTRA_MODULES_PATH by the proper pathname to the <opencv_contrib>/modules value using its browse button.
6. press the configure button followed by the generate button (the first time, you will be asked which makefile style to use)
7. build the opencv core with the method you chose (make and make install if you chose Unix makfile at step 6)
8. to run, linker flags to contrib modules will need to be added to use them in your code/IDE. For example to use the aruco module, "-lopencv_aruco" flag will be added.
如果重新编译，则需要清理编译：
make clean
make编译：
make -j$(nproc)
By default OpenCV will be installed to the /usr/local directory, all files will be copied to following locations: /usr/local/bin - executable files /usr/local/lib - libraries (.so) /usr/local/cmake/opencv4 - cmake package /usr/local/include/opencv4 - headers /usr/local/share/opencv4 - other files (e.g. trained cascades in XML format) Since /usr/local is owned by the root user, the installation should be performed with elevated privileges (sudo): sudo make install 一键获取完整项目代码bash1 Installation root directory can be changed with CMAKE_INSTALL_PREFIX configuration parameter, e.g. -DCMAKE_INSTALL_PREFIX=$HOME/.local to install to current user’s local directory.
sudo make install
