如何在Windows上使用MinGW构建OpenCV 3.2.0

Question

3

这篇文章包含我（以及其他用户）在从源代码构建库时遇到的所有问题。由于没有教程，因此我决定创建这种常见问题解答帖子，将所有解决方案放在一起。希望能够帮到你！配置： OpenCV 3.2.0 MinGW-w64 x86_64-6.1.0-win32-seh-rt_v5-rev0

欢迎在答案中添加更多信息，因为将所有内容放在一个地方更加方便。

哇，太棒了！你知道如何在Windows环境下使用Python中的dlib和OpenCV吗？ - Jeru Luke

这可能适用于StackOver文档，但它不是一个有效的问题。 - usr1234567

@usr1234567 这是一个旨在提问和回答的问题。我认为需要一些更好的解决方案来处理错误3和4，才可以成为一篇文档。 - Alex

@JeruLuke，不幸的是，我没有... - Alex

@Alex 或许你可以在文档部分记录这个答案。这样的内容不应该被浪费。 - Jeru Luke

据我所知，这个问题只会被关闭，而不是删除。一旦它提供的解决方案足够好，我可能会将其移动到文档中。文档是用于文档的 :) - Alex

Download and unpack OpenCV to a folder of your choice.
opencv\sources now contains CMakeLists.txt and all the other files necessary. Configure the project in CMake. CLion users may just open CMakeLists.txt.
- Fix 1: sprintf () family security error.
  Add add_definitions(-DSTRSAFE_NO_DEPRECATE) to the beginning of CMakeLists.txt. This will define STRSAFE_NO_DEPRECATE symbol for the project and suppress the error.
- Fix 2: 'too many sections' as.exe error.
  Add the following lines to the beginning of CMakeLists.txt (source):
```
set(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} "-Wa,-mbig-obj")
set(CMAKE_C_FLAGS ${CMAKE_C_FLAGS} "-Wa,-mbig-obj")
```
- Fix 3: 'the last argument must be an 8-bit immediate'.
  Found nothing better than hardcoding 0x88 instead of mask_lo = _MM_SHUFFLE(2, 0, 2, 0) (binary 10 00 10 00) and 0xDD instead of mask_hi.
  As soon as my question gets a better answer, I will update this paragraph.
- Fix 4: no c++11 threads in MinGW.
  Again, a dirty solution: added #include <mingw.*.h> to <mutex>, <thread>, <condition_variable> before #endif // C++11. (Source)
Build it! It will take about 30-40 minutes.
Find the output folder. It is still a mess but contains a Makefile.
Launch cmd, cd to the output folder and call [path to compiler]\mingw32-make.exe install. (Source)
Voila, your library is in the install folder! Now you can move it to a desired destination and set up environment variables.
