在Matlab中加载.dll会导致'；找不到类型'；问题 我一直希望在Matlab玩这个漂亮的C++ DLL（1），因为我有一些现有的Matlab素材，我认为可以从这个库的功能中受益。但是，每当我运行此命令加载库时： loadlibrary('d3d9Callback.lib','d3d9Callback.h')
我收到大量关于dll中使用的类型存在的警告，以及大量语法错误，显然是由未知类型引起的。以下是警告/错误的开始：在Matlab中加载.dll会导致'；找不到类型'；问题 我一直希望在Matlab玩这个漂亮的C++ DLL（1），因为我有一些现有的Matlab素材，我认为可以从这个库的功能中受益。但是，每当我运行此命令加载库时： loadlibrary('d3d9Callback.lib','d3d9Callback.h'),c++,matlab,dll,C++,Matlab,Dll,我收到大量关于dll中使用的类型存在的警告，以及大量语法错误，显然是由未知类型引起的。以下是警告/错误的开始： Warning: Warnings messages were produced while parsing.

现在我检查了Matlab论坛并尝试了通常的疑义（设置C++编译器，确保它不是32位的DLL上的一个64位DLL，并且确保DLL是‘外部C’）。我开始认为问题在于，dll大量地从directx库以及同一网站的附加dll中提取。也许Matlab不知道它们，这导致了“类型未知”问题？这是我能想到的唯一一件事，但这对我来说没有意义，因为正在加载的库已经编译成dll
不管怎样，我对处理DLL还很陌生，所以我的直觉可能有点不对劲。有没有想过为什么Matlab不能识别这些类型，以及我该如何解决这个问题？由此开始！因此，在MATLAB中，输出的DLL函数看起来是C函数，而不是用于LabVIEW的C++函数。 同样在错误消息的末尾，似乎是另一个dll（d3d9Callback_thunk_pcwin64.dll），缺少一些包含文件，从而导致编译器错误。确保要加载到matlab中的库具有可用于matlab搜索路径的相关DLL 更新看完一些评论！要了解d3d9Callback\u thunk\u pcwin64的未来，有点奇怪，因为您已经确认了64位dll与32位matlab的兼容性。依赖dll是否也需要通过loadlibrary加载，或者只是在搜索路径上？后一个选项并没有改变我所得到的错误：-要在搜索路径上回答，可以考虑AdvApple（）函数。但是在我的更新中，我想知道为什么在上面的错误消息中创建thunk文件时会出错。matlab文档中指出“matlab生成thunk文件，这是64位库的兼容层。”。无论如何，如果很难生成thunk文件，您可以创建一个由matlab调用的适配器dll，它调用实际的dll（适配器应该是简单的代码，以便matlab可以生成thunk dll）。我认为thunk问题（以及所有其他错误）只是matlab类型替换的副产品。我加载其他库时没有遇到thunk问题，所以我认为不是这样。应该有DLL的链接吗？这里有一个链接，指向可以下载构建DLL的项目的站点：
