Matlab Shared C/C++ lib in VS10/12 抛出很多异常答案

【问题标题】：Matlab Shared C/C++ lib in VS10/12 throws a lot exceptionsMatlab Shared C/C++ lib in VS10/12 抛出很多异常
【发布时间】：2012-11-26 21:43:32
【问题描述】：

我的 matlab c/c++ 共享库出现运行时问题。库导出并且应用程序已正确编译和链接。但是在运行时脚本似乎有很多错误。我的应用程序的控制台窗口（显示 matlab 输出）中没有显示错误。但是调试器在运行时会显示很多未捕获的异常。但脚本似乎运行完毕，应用程序正确终止。

需要知道的一些事情：

基于 Win8 Pro x64 构建
Visual Studio 2012（项目设置为VS 2010，安装正确）
Matlab R2012b（32Bit）（64Bit版本也安装了，但据我所知这里没用）
MCR R2012b win32/64 已安装
Matlab Compiler中使用的编译器是VS2010的编译器（使用GUI-compiler编译）

嗯，这是我要导出到共享库的 m 文件：

% Create video input object. 
vid = videoinput('winvideo', 1, 'YUY2_320x240')

% Set video input object properties for this application.
set(vid,'TriggerRepeat',Inf);
vid.FrameGrabInterval = 3;

% Set value of a video source object property.
vid_src = getselectedsource(vid);
set(vid_src,'Tag','motion detection setup');
set(vid,'ReturnedColorSpace','rgb');

% Create a figure window.
figure; 
% wiener filter neighbourhood
wienerFilter = [5 5];
% Start acquiring frames.
start(vid)

% Calculate difference image and display it.
while(vid.FramesAcquired<=200) % Stop after 200 frames
    data = getdata(vid,2);

    first_img = wiener2(rgb2gray(data(:,:,:,1)), wienerFilter);
    second_img = wiener2(rgb2gray(data(:,:,:,2)), wienerFilter);

    bw_img = im2bw(first_img);

    diff_im = imabsdiff(first_img,second_img);

    subplot(1,3,1), imshow(first_img);
    subplot(1,3,2), imshow(second_img);
    subplot(1,3,3), imshow(diff_im);

end

stop(vid)

delete(vid)
close(gcf)

如果您的计算机上有网络摄像头，脚本应该可以正常运行！

现在是 C++ 主文件：

#include "stdafx.h"
#include "MatlabCompilerSample.h"

#pragma comment(lib, "MatlabCompilerSample.lib")

int _tmain(int argc, _TCHAR* argv[])
{
    /* Call the MCR and library initialization functions */
    if( !mclInitializeApplication(NULL,0) )
    {
        const char* message = mclGetLastErrorMessage();
        printf_s(message);
        fprintf(stderr, "Could not initialize the application.\n");
        exit(1);
    }

    if (!MatlabCompilerSampleInitialize())
    {
        fprintf(stderr,"Could not initialize the library.\n");
        exit(1);
    }

    /* Call the implementation function */
    WebcamSample();

    /* Call the library termination function */
    MatlabCompilerSampleTerminate();

    mclTerminateApplication();
    return 0;
}

到目前为止看起来还不错？加载一堆 dll 后，混乱开始了。查看抛出的异常和废话：

整个文件有 6000 行...如果有必要我会发布它！毕竟它停在这里：

我会很高兴收到每一个提示，在此先感谢！

【问题讨论】：

许多这些消息似乎与没有为 DLL 定义调试器符号这一事实有关。它在某处崩溃，尝试进入调试模式并失败。
还有。你试过编译简单的“hello world”类型的程序吗？您的编译器管道通常运行时没有错误吗？我最喜欢的技巧之一是在 matlab 脚本中重新添加/添加行，看看它何时会失败。

【解决方案1】：

这些都是第一次机会例外，并不意味着有问题。我在以前的工作中经常看到它们，Matlab 倾向于产生很多异常，这两者都不是真正的问题。

http://blogs.msdn.com/b/davidklinems/archive/2005/07/12/438061.aspx

第一次机会异常是否意味着我的代码存在问题？第一次机会异常消息通常并不意味着代码中存在问题。对于优雅地处理异常的应用程序/组件，第一次机会异常消息让开发人员知道遇到并处理了异常情况。

【讨论】：

真正的问题是 MATLAB 在初始化和执行期间确实抛出了 lot 的异常。它们显然是在内部处理的，但在我看来，这表明它们的编程模型包括使用异常而不是其他更合适的流控制方法以及吞下潜在有效异常的反模式（当我调试基于 MATLAB 的应用程序时）我经常会发现调试器会因 AccessViolation 异常而停止，读取一些接近零的内存位置。）
