我的matlab c/c++ 共享库出现运行时问题。库导出并且应用程序被正确编译和链接。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显示了很多未捕获的异常。但是脚本似乎运行并且应用程序正确终止。

一些事情要知道：

  • 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，不过这里没用，据我所知）
  • MCR R2012b win32/64 已安装
  • Matlab 中使用的编译器 Compiler 是VS2010 的一种（用GUI-compiler 编译）

好吧，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，则脚本应该可以正常运行！

现在主要的 C++ 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;
}

到现在还好看吗？加载一堆 dll 后，混乱开始了。查看抛出的异常和废话：

'MatlabCompilerCPPExample.exe' (Win32): Loaded 'C:\Windows\WinSxS\x86_microsoft.vc90.mfcloc_1fc8b3b9a1e18e3b_9.0.30729.6161_none_49768ef57548175e\MFC90DEU.DLL'. Module was built without symbols.

整个文件有 6000 行...如果有必要我会发布它！毕竟它在这里停止了：

我会很高兴每一个提示，提前谢谢！

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，而 Matlab 倾向于产生很多异常，但这都不是真正的问题。

第一次机会异常是否意味着我的代码存在问题？首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。
