在opencv中使用静态库代替动态库
我在visual studio 2012中有一个使用opencv动态库的项目。它很好地编译、链接和工作。
我想更改项目，使其使用静态库而不是动态库。
我将项目VC++目录中的库目录从
C:\thirdparty\opencv\build\x86\vc11\lib至: C:\thirdparty\opencv\build\x86\vc11\staticlib
但是当我想要构建这个项目时，我得到了很多链接器错误，例如：
Error 110 error LNK2001: unresolved external symbol _TIFFWriteScanline myproject\opencv_highgui245.lib(grfmt_tiff.obj) 更重要的是，像这样的许多错误：
Error 1 error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MT_StaticRelease' doesn't match value 'MD_DynamicRelease' in myproject.obj myproject\opencv_core245.lib(system.obj) 要将使用动态库的项目转换为使用静态库，我还应该做哪些更改？
编辑1个
将/md更改为/mt并在输入库列表中添加一些新库后：
opencv_calib3d245.lib
opencv_contrib245.lib
opencv_core245.lib
opencv_features2d245.lib
opencv_flann245.lib
libtiff.lib
libpng.lib
libjpeg.lib
libjasper.lib
IlmImf.lib
zlib.lib
opencv_gpu245.lib
opencv_haartraining_engine.lib
opencv_highgui245.lib
opencv_imgproc245.lib
opencv_legacy245.lib
opencv_ml245.lib
opencv_nonfree245.lib
opencv_objdetect245.lib
opencv_photo245.lib
opencv_stitching245.lib
opencv_ts245.lib
opencv_video245.lib
opencv_videostab245.lib我得到了一些新的错误：
Error 9 error LNK2001: unresolved external symbol _AVIFileCreateStreamA@12 myproject\opencv_highgui245.lib(cap_vfw.obj)
Error 8 error LNK2001: unresolved external symbol _AVIFileGetStream@16 myproject\opencv_highgui245.lib(cap_vfw.obj)
Error 5 error LNK2001: unresolved external symbol _AVIFileInit@0 myproject\opencv_highgui245.lib(cap_vfw.obj)
Error 7 error LNK2001: unresolved external symbol _AVIFileOpenA@16 myproject\opencv_highgui245.lib(cap_vfw.obj) 显然有一些库丢失了，但是是哪一个呢？
编辑2需要向列表中添加更多的库。库的完整列表如下：
opencv_calib3d245.lib
opencv_contrib245.lib
opencv_core245.lib
opencv_features2d245.lib
opencv_flann245.lib
libtiff.lib
libpng.lib
libjpeg.lib
libjasper.lib
IlmImf.lib
zlib.lib
opencv_gpu245.lib
opencv_haartraining_engine.lib
opencv_highgui245.lib
opencv_imgproc245.lib
opencv_legacy245.lib
opencv_ml245.lib
opencv_nonfree245.lib
opencv_objdetect245.lib
opencv_photo245.lib
opencv_stitching245.lib
opencv_ts245.lib
opencv_video245.lib
opencv_videostab245.lib
Vfw32.Lib
comctl32.lib这就解决了问题。

通过将项目的运行时库更改为/MTd，我可以让静态库在VS2013中工作
然后包含这些链接器>>输入>>附加依赖项：

如果您使用CMake构建，那么它非常简单，因为它是OpenCV CMake选项之一；只需将BUILD_WITH_STATIC_CRT设置为off即可。例如：在CMake命令行上

对于带有OpenCV 3.0.0的Visual Studio2012，这些问题仍然存在，并且此线程中的解决方案是相关的。下面是我让它工作的设置：
Windows的系统环境变量
在Windows的系统环境变量中设置：OPENCV_DIR = D:\OpenCV\build\x64\v11 (将D:\OpenCV\替换为您的opencv路径。此外，64位计算机使用x64，32位计算机使用x86 )。
在AdditionalLibraryDirectories中使用统计表
将其他库目录(视图>属性页>配置属性>链接器>常规>其他库目录)设置为：$(OPENCV_DIR)\staticlib;%(AdditionalLibraryDirectories)
运行时库
将Code Generation > Runtime Library更改为per uosɐſ's answer的Multi-threaded Debug (/MTd)，否则将出现以下错误：
Error 1 error LNK2038: mismatch detected for 'RuntimeLibrary': value
'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in Source.obj
C:\Users\...\documents\visual studio 2012\Projects\OpenCVTest2\OpenCVTest2\opencv_core300d.lib(alloc.obj) OpenCVTest2最后，附加依赖项列表
我的附加依赖项必须包含staticlib目录中的所有库名称。注意版本号；因为我使用的是OpenCV 3.0.0，所以文件名以*300d.lib结尾。我相信comctl32.lib和vfw32.lib不在统计表中，但我添加了它们以防万一(视图>属性页>配置属性>链接器>输入>附加依赖项)：
opencv_calib3d300d.lib
