我一直希望在Matlab中使用[这个漂亮的C ++ dll] [1]，因为我有一些现有的Matlab，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')
关于dll中使用的类型的存在，我得到了一个令人讨厌的大量警告，以及一些疯狂的语法错误，显然源于未知类型。这是警告/错误的开始：
Warning: Warnings messages were produced while parsing. Check the functions you
intend to use for correctness. Warning text can be viewed using:
[notfound,warnings]=loadlibrary(...)
> In loadlibrary at 360
Error loading library intermediate output follows.
The actual error is at the end of this output.

现在我已经检查了Matlab论坛并尝试了常见的嫌疑人（设置c ++编译器，确保它不是32位Matlab上的64位dll，并确保dll是'extern c'）。我开始认为问题在于问题是dll大量来自directx库以及来自同一网站的额外dll。也许Matlab不了解它们，这导致了“类型未知”的问题？这是我唯一能想到的，但它对我来说没有意义，因为加载的库已经编译成了一个dll。
无论如何，我对处理dll很陌生，所以我的直觉可能已经过时了。有关为什么Matlab无法识别类型以及如何解决问题的任何想法？
答案 0 :(得分：1)
从这discussion开始！在SO上，看起来导出的dll函数是C函数，而不是matlab中loadLibrary的C ++函数。
同样在错误消息的末尾，它似乎是另一个dll（d3d9Callback_thunk_pcwin64.dll），并且缺少一些包含文件，因此编译错误。确保要在matlab中加载的库具有可用于matlab搜索路径的相关dll。
<强>更新
阅读一些评论后in matlab forum！要了解d3d9Callback_thunk_pcwin64的来源，有点奇怪，因为你提到你已经确认了64位dll和32位matlab兼容性。
