c++ - 如何在 Matlab 中导入 C++ dll

问题描述

我正在努力在 Matlab (2019a) 中导入 C++ (2017) dll。

特别是，由于我不熟悉 C++，因此我尝试创建 https://github.com/MicrosoftDocs/cpp-docs/blob/master/docs/build/walkthrough-creating-and-using- 中定义的MathLibrary a-动态链接库-cpp.md。我根据指南创建了库，编译了 Debug 和 Release (x86)，并且使用描述的 MathClient 导入工作正常。

但是，我尝试在 Matlab 中导入库（在将所需文件夹添加到当前路径之后）：

        if libisloaded('MathLibrary') == 0
           handle = loadlibrary('MathLibrary.dll','MathLibrary.h');
        end

它会引发大量错误：

        Warning: Message from C preprocessor:
        cl : command line warning D9027: source file 'C:\Users\miche\source\repos\MathLibrary\Release\MathLibrary.lib' ignored
        cl : command line warning D9021 : no operation performed

        > In loadlibrary 
        Error loading library intermediate output follows.
        The actual error is at the end of this output.
        *********

        Warning no reference to header 'MathLibrary' added with addheader was found in source.
        *********

        /nologo  -I"D:\Program Files\MATLAB\R2019a\bin"
        -I"C:\Users\user\source\repos\MathLibrary\Release"
        "MathLibrary_thunk_pcwin64.c" -LD
        -Fe"MathLibrary_thunk_pcwin64.dll"
        MathLibrary_thunk_pcwin64.c

        C:\Users\miche\source\repos\MathLibrary\Release\MathLibrary.lib(2):
        error C2018: character '0x60' unknown

然后就这样继续下去，有很多字符错误。我的代码有什么问题？我该如何解决这个问题？
