OpenCV错误：“链接：致命错误LNK1104：无法打开文件'opencv_core300d.lib'”

Question

我正在尝试在Visual Studio + opencv中编译一个简单的代码，但出现此错误。

代码：

#include <cstdio.h>
#include <opencv2\opencv.hpp>

void main(){  
   std::cout<<CV_VERSION;
}

输出：

error LNK1104: cannot open file 'opencv_core300d.lib'
error MSB6006: "link.exe" exited code1104.

Answer 1

您可能添加了正确的包含目录，但是忘记了链接实际的库。

在Configuration Properties-Linker-General-Additional Library Directories下，您需要添加以下内容：$(OPENCV_DIR)\staticlib;

[OPENCV_DIR指向您的构建文件夹。例如：E:\opencv\build\x86\vc12。

完成之后，还需要在Configuration Properties-Linker-Input-Additional Dependencies]下添加以下几行

IlmImfd.lib
libjasperd.lib
libpngd.lib
libjpegd.lib
libtiffd.lib
libwebpd.lib
opencv_calib3d300d.lib
opencv_core300d.lib
opencv_features2d300d.lib
opencv_flann300d.lib
opencv_hal300d.lib
opencv_highgui300d.lib
opencv_imgcodecs300d.lib
opencv_imgproc300d.lib
opencv_ml300d.lib
opencv_objdetect300d.lib
opencv_photo300d.lib
opencv_shape300d.lib
opencv_stitching300d.lib
opencv_superres300d.lib
opencv_ts300d.lib
opencv_video300d.lib
opencv_videoio300d.lib
opencv_videostab300d.lib
zlibd.lib
ippicvmt.lib
comctl32.lib
vfw32.lib

您只需要添加所需的内容，但是添加全部内容没有消极的一面。然后，您确定您不会忘记任何事情。
