windows 静态编译 gocv

当前使用版本

  • gocv：0.39.0
  • go：1.21.13
  • opencv：4.10.0
  • MinGW-W64：8.1.0
  • CMake：3.31.1

安装 MinGW-W64

下载 [x86_64-8.1.0-release-posix-seh-rt_v6-rev0.7z](https://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win64/Personal Builds/mingw-builds/8.1.0/threads-posix/seh/x86_64-8.1.0-release-posix-seh-rt_v6-rev0.7z/download)，解压出来是 mingw64 文件夹。

将 mingw64 文件夹移动到任意目录安装，如 D:\mingw64

将 bin 目录 D:\mingw64\bin 添加到环境变量 PATH

安装 CMake

下载 CMake https://cmake.org/download/, 解压，同样将 bin 目录添加到环境变量 PATH

下载 gocv

在 go 项目目录下执行命令，把 gocv 的源码下到本地。一般会下到 pkg\mod\gocv.io\x 目录

1
go get -u -d gocv.io/x/gocv

静态编译 opencv

注意：编译opencv前需要将系统环境变量中python先删除，否则编译会出错

进到 gocv 这个目录, 修改 win_build_opencv.cmd 脚本, 在 cmake 命令末尾添加 -DWITH_QUIRC=ON。

quirc 在 gocv 中使用，但在 opencv 的默认规则中被禁用，因此需要通过 -DWITH_QUIRC=ON 手动启用它。

1
cmake C:\opencv\opencv-4.10.0 -G "MinGW Makefiles" -BC:\opencv\build -DENABLE_CXX11=ON -DOPENCV_EXTRA_MODULES_PATH=C:\opencv\opencv_contrib-4.10.0\modules -DBUILD_SHARED_LIBS=OFF -DWITH_IPP=OFF -DWITH_MSMF=OFF -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF -DBUILD_PERF_TESTS=ON -DBUILD_opencv_java=OFF -DBUILD_opencv_python=OFF -DBUILD_opencv_python2=OFF -DBUILD_opencv_python3=OFF -DBUILD_DOCS=OFF -DENABLE_PRECOMPILED_HEADERS=OFF -DBUILD_opencv_saliency=OFF -DBUILD_opencv_wechat_qrcode=ON -DCPU_DISPATCH= -DOPENCV_GENERATE_PKGCONFIG=ON -DWITH_OPENCL_D3D11_NV=OFF -DOPENCV_ALLOCATOR_STATS_COUNTER_TYPE=int64_t -Wno-dev -DWITH_QUIRC=ON

然后运行 win_build_opencv.cmd static 脚本，需要添加 static 参数设置为静态编译 opencv，最好是使用 cmd 执行，使用 power shell 需要额外手动确认下载文件

opencv 编译成功后会安装到 C 盘的 C:\opencv\build\install 文件夹下

系统路径中添加 C:\opencv\build\install\x64\mingw\bin

静态编译测试gocv

在gocv目录下，使用命令 go build -tags "opencvstatic windows" -o test.exe cmd\version\main.go

运行 test.exe还是会缺少libgcc_s_seh-1.dll,libstdc+ +-6.dl，libwinpthread-1.dll

如果当前go版本和gocv使用的版本不同会报错go\pkg\tool\windows_amd64\link.exe: running g++ failed: exit status 1

修改gocv目录下的cgo_static_windows.go,contrib/cgo_static_windows.go 和cuda/cgo_static_windows.go

在-LC:/opencv/build/install/x64/mingw/staticlib前添加参数--static

再次执行build命令，test.exe正常运行并输出

gocv version: 0.39.0
opencv lib version: 4.10.0

或者用标签-tags customenv使用自定义环境

使用自定义环境是需要在执行build命令设置环境，并且每次build都需要设置一次。

不想每次都设置环境的话，可以直接添加到系统环境变量中
