build tool
visual studio 2017
1. Compile protobuf
1. Download protobuf
protobuf-3.11.2：https://github.com/google/protobuf/archive/v3.11.2.zip
2. Unzip
Unzip to: D:\protobuf-3.11.2
3. Compile
open windows powershell
mkdir protobuf_build
cd protobuf_build
cmake -A x64 -DCMAKE_INSTALL_PREFIX=%cd%/install -Dprotobuf_BUILD_TESTS=OFF -Dprotobuf_MSVC_STATIC_RUNTIME=OFF ../cmake
cmake --build . --config Release -j 2
cmake --build . --config Release --target install
The Vulkan SDK is used to call the GPU, so I won’t go into details here
Two, compile opencv
1. Download cmake
Official website link: Download | CMake
2. Download opencv and opencv_contrib
opencv：Release OpenCV 4.8.0 · opencv/opencv · GitHub
opencv_contrib：Tags · opencv/opencv_contrib · GitHub
After installation, place it in the settings folder, such as,
3. Use cmake to compile opencv
source code：D:\opencv\opencv-4.8.0\sources
build the binaries：D:\opencv\tools
After setting, click configure, then select the vs version and operating system, and click finish
After the first configure, the following situation will appear,
Find "OPENCV_EXTRA_MODULES_PATH" in the red area, enter: D:\opencv\opencv_contrib-4.8.0\modules to install the corresponding version of the extension package
If you want to generate opencv_world.lib, check "BUILD_opencv_world"
Configure again, the red area will disappear,
Then generate,
Next, you can find and open the opencv solution under D:\opencv\tools: D:\opencv\tools\OpenCV.sln
Right-click the solution -> generate the solution, right-click the install of cmaketargets -> only for the project -> only generate INSTALL
3. Compile ncnn
Unzip to drive D, such as: D:\ncnn
cd D:\ncnn
mkdir -p protobuf_build
cd protobuf_buildStart compiling ncnn,
## 注意把<protobuf-root-dir>换成你的protobuf的目录，如：D:/protobuf-3.11.2
## DNCNN_VULKAN设成OFF
## 指定DOpenCV_DIR的路径，如：D:/opencv/tools
cmake -A x64 -DCMAKE_INSTALL_PREFIX=%cd%/install -DProtobuf_INCLUDE_DIR=D:/protobuf-3.11.2/protobuf_build/install/include -DProtobuf_LIBRARIES=D:/protobuf-3.11.2/protobuf_build/install/lib/libprotobuf.lib -DProtobuf_PROTOC_EXECUTABLE=D:/protobuf-3.11.2/protobuf_build/install/bin/protoc.exe -DNCNN_VULKAN=OFF .. -DOpenCV_DIR=D:/opencv/tools
cmake --build . --config Release -j 2
cmake --build . --config Release --target install
So far, the compilation of ncnn on windows has been completed
