C++ openCV 243使用静态libs错误LNK2019

我试图在64位vs10控制台应用程序中使用openCV243静态库。我的操作系统是win7 64位

我已包括以下LIB：

#pragma comment(lib,"../final_test/libs/staticlib/opencv_core243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_highgui243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_imgproc243.lib")       
#pragma comment(lib,"../final_test/libs/staticlib/opencv_video243d.lib")

运行库是：多线程（/MT）

我得到以下链接错误

有人能帮我解决这个问题吗？谢谢。

您需要链接到MS

vfw32.lib

库。

只需在您的头文件中执行此操作。它应该工作得很好

#include "opencv2/opencv.hpp"
#pragma comment(lib, "vfw32.lib")
#pragma comment( lib, "comctl32.lib" )

---

当您不包含“highgui”库时，它会编译吗？这可能也会有帮助：谢谢您的评论。不幸的是，如果没有highgui，项目将无法编译。好的，您是否也在项目配置中将这些lib文件指定为其他依赖项？这可能是必要的。此外，comctl32.lib是needed@ChaiNadig在furqan的回答中或者在VC++2010 Express中添加pragmas：项目属性（Alt-F7）->配置属性->链接器->输入；单击附加依赖项值上的下拉菜单，编辑…，将库文件列表粘贴到上面。您将在单独的行中使用vfw32.lib和comctl32.lib，还有来自%OPENCV\u DIR%\build\x86\vc10\staticlib的libs。因此，没有64位版本我更愿意链接？或者，这些文件是否自动64位保存在我的system32文件夹中？我正在运行64位的Windows7。我遇到的问题是，由于我是64位编译的，

cv:VideoCapture:：readMat（cv\u OUT Mat&image）

返回一个空的

cv:：Mat

您应该在cmake文件或类似文件中定义依赖项。链接pragma一开始是一个糟糕的概念。为什么要在编译期间定义链接时间依赖关系？它们也是特定于编译器的，不可移植。这些库的名称中当然有32位，因为它们是win32名称的一部分，而不是因为它们必须是32位库。注：我遇到了同样缺少符号的问题，在我的例子中，我添加了两个win32库和两个库列表，以链接到我的conan opencv包中。
