Question

我在OSX 10.10上。我正在尝试运行一个使用以下库和程序的项目演示：

MATLAB R2014b 64位。
通过Homebrew安装的OpenCV 2.4.10.1。
VLFeat 0.9.20。
mexopencv。

我在MATLAB中运行mex -setup，将编译器设置为clang。

VLFeat和mexopencv的路径已添加到MATLAB的startup.m文件中。

当我尝试运行demo_test.m文件时，我在MATLAB中遇到以下错误：

Invalid MEX-file '/Users/maverick/Documents/Project/mexopencv-master/+cv/private/CascadeClassifier_.mexmaci64':
dlopen(/Users/maverick/Documents/Project/mexopencv-master/+cv/private/CascadeClassifier_.mexmaci64, 6): Symbol not found:

Error in cv.CascadeClassifier (line 33)
            this.id = CascadeClassifier_(filename);

Error in faceAlign (line 8)
    detector = cv.CascadeClassifier('haarcascade_frontalface_alt2.xml');


Error in regressionFit (line 11)
            [shape, rat, ~, init_s] = faceAlign(img, [], [], R{round_number}, b{round_number}, [], pad, [1:66], 0);


Error in demo_test (line 16)
shape = regressionFit(img, [], R, b);

我知道该项目有效，因为我已经在另一台计算机上试过了。如何解决此错误并使项目运行？感谢。

编辑1：
这是我运行otool -L（相当于ldd）...

时的输出

    $ otool -L /Applications/MATLAB_R2014b.app/bin/maci64/libopencv_ocl.2.4.dylib

编辑2：这是CascadeClassifier_.mexmaci64

上的otool -L的输出

我错过了一些图书馆吗？ PATH配置不正确吗？

Matlab捆绑了自己的计算机视觉库。因此，即使安装了OpenCV，它也会首先尝试使用它们。

解决方案是将这些捆绑的库移动到另一个文件夹（以便在出现问题时进行备份），然后sym将实际的OpenCV库链接到之前由捆绑库填充的位置。

如果在执行此操作后，您收到任何错误，那么可能是因为Matlab再次使用自己的库。对这个库再次执行相同的过程。
