问题
I'm trying to use openCV243 static libs in 64bit vs10 console application. My OS is win7 64 bit.
I've included following libs:
#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")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_flann243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_features2d243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_objdetect243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_core243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_calib3d243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_legacy243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_features2d243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_ml243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/libjpeg.lib")
#pragma comment(lib,"../final_test/libs/staticlib/libpng.lib")
#pragma comment(lib,"../final_test/libs/staticlib/libtiff.lib")
#pragma comment(lib,"../final_test/libs/staticlib/libjasper.lib")
#pragma comment(lib,"../final_test/libs/staticlib/zlib.lib")
#pragma comment(lib,"../final_test/libs/staticlib/IlmImf.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_videostab243")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_contrib243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_nonfree243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_photo243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_stitching243.lib")
#pragma comment(lib,"../final_test/libs/staticlib/IlmImf.lib")
#pragma comment(lib,"../final_test/libs/staticlib/opencv_ts243.lib")
The runtime library is: Multi-threaded (/MT)
I get following linking errors.

...
can anyone help me to rid of this problem? Thank you.
回答1:
You need to link with MS vfw32.lib library.
回答2:
just do this in ur header file. It should work perfectly.
#include "opencv2/opencv.hpp"
#pragma comment(lib, "vfw32.lib")
#pragma comment( lib, "comctl32.lib" )
