抑制状态错误 LNK1104 无法打开文件 'IlmImfd.lib'

Question

我的链接部分似乎有错误，尽管我的代码编译没有错误。

我这样设置属性：

我还在 Linker -> General -> Additional library directories 和 Linker -> Input -> Additional Dependencies

之后还是报错

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 
cv::Ptr<class cv::face::FisherFaceRecognizer> __cdecl

Answer 1

您可能添加了正确的包含目录，但您忘记了 link 实际的库。

在 Configuration Properties - Linker - General - Additional Library Directories 下你需要添加以下内容： $(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

您只需要添加您需要的那些，但将它们全部添加也没有负面影响。那么，你确定你没有忘记任何东西。
