OpenCV使用CMake和MinGW-w64的编译安装

前言

之前写过的一篇博文:OpenCV使用CMake和MinGW的编译安装及其在Qt配置运行 是使用 32 位的 MinGW 在 Windows 下编译 OpenCV 生成 32 位的 dll。

而这篇博文是使用 64 位的 MinGW 编译 OpenCV 生成 64 位的 dll。

因为博主没有 64 位 qmake,所以没勾选 WITH_QT

2018年10月13日为 OpenCV-4.0.0-alpha 而修改,主要改了 “编译 OpenCV 常见错误”

编译好的 OpenCV(MinGW 版):

Github . huihut/OpenCV-MinGW-Build

软件环境

安装 MinGW-w64 并配置环境变量

下载安装:MinGW-x64-4.8.1-release-posix-seh-rev5

为系统(用户)变量 Path 添加 E:\MinGW-w64\x64-4.8.1-release-posix-seh-rev5\mingw64\bin

使用 CMake 生成 OpenCV 的 Makefile

打开 cmake-gui,设置源码和生成路径:

  • Where is the source code: E:/opencv_341/opencv/sources
  • Where to build the binaries: E:/opencv_341/opencv_mingw64_build

点击 Configure,设置编译器

  • Specify the generator for this project: MinGW Makefiles
  • Specify native compilers
  • Next
  • Compilers C: E:\MinGW-w64\x64-4.8.1-release-posix-seh-rev5\mingw64\bin\gcc.exe
  • Compilers C++: E:\MinGW-w64\x64-4.8.1-release-posix-seh-rev5\mingw64\bin\g++.exe
  • Finish

编译配置:

  • 勾选 WITH_OPENGL
  • 勾选 ENABLE_CXX11
  • 不勾选 WITH_IPP
  • 不勾选 ENABLE_PRECOMPILED_HEADERS

点击 Configure,Generate 生成 Makefile

解决

打开E:\MinGW-w64\x64-4.8.1-release-posix-seh-rev5\mingw64\x86_64-w64-mingw32\include\aviriff.h

发现第一行的多行注释少了个/符号,加上保存,如下:

4
/**
* This file is part of the mingw-w64 runtime package.
* No warranty is given; refer to the file DISCLAIMER within this package.
*/

然后重新 Configure-Generate-mingw32-make 就好了。

原因

因为 MinGW 不能编译 OpenCV 的 cap_msmf 那部分代码,具体见我提的 Issue:Failed to compile opencv-4.0.0-alpha using mingw-w64

解决

所以,在 cmake-gui 编译配置中:

  • 不勾选 WITH_MSMF

然后重新 Configure-Generate-mingw32-make

mingw32-make[1]: *** [modules/calib3d/CMakeFiles/opencv_calib3d.dir/all] Error 2
Makefile:161: recipe for target 'all' failed
mingw32-make: *** [all] Error 2

原因

因为 OpenCV 在 chessboard.cppchessboard.hpptest_chesscorners.cpp 这些代码中有 BUG,使用的应该是 CV_PI 而不是 M_PI 导致的。具体见我提的 Issue:Failed to compile opencv-4.0.0-alpha using mingw-w64

解决

然后重新 Configure-Generate-mingw32-make
