抑制状态错误LNK1104无法打开文件'IlmImfd.lib'

Question

即使我的代码编译没有错误，我似乎也有链接部分的错误。

我像这样设置属性：

我还添加了所需的文件 Linker -> General -> Additional library directories和 Linker -> Input -> Additional Dependencies

之后它仍然给我一个错误。

代码：

#include "opencv2/core.hpp"
#include "C:/Users/Downloads/opencv_contrib-master/opencv_contrib-master/modules/face/include/opencv2/face.hpp"
#include "opencv2/highgui.hpp"
#include "opencv2/imgproc.hpp"
#include "opencv2/objdetect.hpp"

#include <iostream>
#include <fstream>
#include <sstream>

using namespace cv;
using namespace cv::face;
using namespace std;

（输出）错误行：

Severity Code Description Project File Line Suppression State
Error LNK1104 cannot open file 'IlmImfd.lib'    opencvTry

（输出）当我尝试使用包含lib文件的相同代码重做项目时：

Severity    Code    Description Project File    Line    Suppression State
Error   LNK2019 unresolved external symbol "public: static struct

您可能添加了正确的include目录，但是您忘记链接实际的库。

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。

完成后，您还需要在Common Properties - Linker - Input - Additional Dependencies

下添加以下行

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

你只需要添加你需要的那些，但是添加它们并没有消极的一面。然后，你确定你没有忘记任何事情。
