OpenCV使用CodeBlocks在Linux中编译Eigenface.cpp

我想用CodeBlocks或Linux终端编译以下OpenCV程序。

http://plaza.ufl.edu/tyler727/imdl/src/eigenface.cpp

    line 57:   nTrainFaces = loadFaceImgArray("/home/hacker/data/Eigenfacecpp/train.txt");
    line 192: // load test images and ground truth for person number
             nTestFaces = loadFaceImgArray("/home/hacker/data/Eigenfacecpp/test.txt");
    // project the training images onto the PCA subspace
    projectedTrainFaceMat = cvCreateMat(nTrainFaces, nEigens, CV_32FC1);
    for(i=0; i<nTrainFaces; i++)
    {
        cvEigenDecomposite(faceImgArr[i],
                           nEigens,
                           eigenVectArr,
                           0, 0,
                           pAvgTrainImg,
line 78:                    projectedTrainFaceMat->data.fl + i*nEigens);
    }
     cvCalcEigenObjects(nTrainFaces,
                        (void*)faceImgArr,
                        (void*)eigenVectArr,
                        CV_EIGOBJ_NO_CALLBACK,
                        0,
                        0,
                        &calcLimit,
                        pAvgTrainImg,
line 154:                eigenValMat->data.fl);
        //project the test image onto the PCA subspace
        cvEigenDecomposite(faceImgArr[i],
                           nEigens,
                           eigenVectArr,
                           0, 0,
                           pAvgTrainImg,
line 211:                   projectedTestFace);

我得到了这些错误：

Compiling: eigenface.cpp

我不明白我做错了什么。我认为这是愚蠢的东西，但我找不到它。

代码块中的编译器和调试器设置：

链接器设置->其他选项：-lopencv_core -lopencv_objdetect -lopencv_imgproc -lopencv_highgui

搜索目录->编译器：/usr/local/include/opencv搜索目录->链接器：/usr/lib

我在这里做错了什么？请帮我解决这个问题。
