Visual C++ :: Compare Two Histograms In OpenCV?

I am tying to compare two histograms, but it gives error. Here I have given my code, histogram file and error message. Histogram file 3*5 matrix(output_test.txt):

1 2 3 4 5
5 2 1 4 2
2 1 2 4 2

code:

Code:
int main(..........)
{
................................................
Mat first_histogram(1,feature_vector_size, CV_32F);
Mat second_histogram(1,feature_vector_size, CV_32F);

[Code]....

Error message: error LNK2019: unresolved external symbol "double __cdecl cv::compareHist(class cv::Mat const &,class cv::Mat const &,int)" (?compareHist@cv@@YANABVMat@1@0H@Z)
