ffmpeg问题：

CMake Error at cmake/OpenCVUtils.cmake:1043 (file):
file DOWNLOAD HASH mismatch
for file: [D:/openCV/opencv-3.2.0/3rdparty/ffmpeg/downloads/f081abd9d6ca7e425d340ce586f9c090/opencv_ffmpeg.dll]

CMake Error at cmake/OpenCVUtils.cmake:1047 (message):
Failed to download opencv_ffmpeg.dll.  Status=7;"Couldn't connect to

解决方法：

1. 在最上面链接中手动下载ffmpeg目录中的内容，解压。（仓库中存了一份，也可以直接在这里下载）
2. 复制opencv_ffmpeg.dll、opencv_ffmpeg_64.dll、ffmpeg_version.cmake到xxx\opencv-3.2.0\3rdparty\ffmpeg目录下。
3. 更改ffmpeg.cmake文件为

message(STATUS "FFMPEG: Package successfully downloaded")
include(${CMAKE_CURRENT_LIST_DIR}/ffmpeg_version.cmake)

ippicv问题：

CMake Error at 3rdparty/ippicv/downloader.cmake:73 (file):
  file DOWNLOAD HASH mismatch
    for file: [D:/openCV/opencv-3.2.0/3rdparty/ippicv/downloads/windows-04e81ce5d0e329c3fbc606ae32cad44d/ippicv_windows_20151201.zip]

CMake Error at 3rdparty/ippicv/downloader.cmake:77 (message):

解决方案：

1. 在最上面链接中手动下载ippicv目录中的内容，解压。（仓库中存了一份，也可以直接在这里下载）
2. 打开xxx\opencv_3rdparty-ippicv-master_20170418\ippicv\ippicv_2017u2_win_ia32_20170418.zip解压ippicv_wind
3. 复制ippicv_wind到目录D:\openCV\opencv-3.2.0\3rdparty\ippicv\unpack（unpack是新建的文件夹）
4. 修改downloader.cmake内容为

#
# The script downloads ICV package
#
# On return this will define:
# OPENCV_ICV_PATH - path to unpacked downloaded package
#

function(_icv_downloader)
  # Commit SHA in the opencv_3rdparty repo
  set(IPPICV_BINARIES_COMMIT "81a676001ca8075ada498583e4166079e5744668")
  # Define actual ICV versions
  if(APPLE)
    set(OPENCV_ICV_PACKAGE_NAME "ippicv_macosx_20151201.tgz")
    set(OPENCV_ICV_PACKAGE_HASH "4ff1fde9a7cfdfe7250bfcd8334e0f2f")
    set(OPENCV_ICV_PLATFORM "macosx")

  elseif(UNIX)
    if(ANDROID AND NOT (ANDROID_ABI STREQUAL x86 OR ANDROID_ABI STREQUAL x86_64))
      return()
    endif()
    set(OPENCV_ICV_PACKAGE_NAME "ippicv_linux_20151201.tgz")
    set(OPENCV_ICV_PACKAGE_HASH "808b791a6eac9ed78d32a7666804320e")

    set(OPENCV_ICV_PLATFORM "windows")
    set(OPENCV_ICV_PACKAGE_SUBDIR "/ippicv_win")
  else()
    return() # Not supported
  endif()

  set(OPENCV_ICV_UNPACK_PATH "${CMAKE_CURRENT_LIST_DIR}/unpack")
  set(OPENCV_ICV_PATH "${OPENCV_ICV_UNPACK_PATH}${OPENCV_ICV_PACKAGE_SUBDIR}")

  message(STATUS "ICV: Package successfully downloaded")
  set(OPENCV_ICV_PATH "${OPENCV_ICV_PATH}" PARENT_SCOPE)
endfunction()

_icv_downloader()

编译问题

Error 4 error C1083: Cannot open include file: 'ipp.h': No such file or directory D:\openCV\opencv-3.2.0\modules\core\include\opencv2\core\private.hpp 200

解决方案：打开cmake 取消勾中with_ipp

cmake完之后打开OpenCV.slu Debug 32位

rebuild生成库就over
