在.NET中使用C ++ DLL [英] Use C++ DLL in .NET

问题描述

我昨天问这个问题，关于使用Cygwin编译器生成一个可以被.NET使用的C ++ DLL：

I asked this question yesterday about using the Cygwin compiler to produce a C++ DLL that can be used by .NET: Using C++ app in .NET

The solution was to compile the C++ application using Visual C++ rather than Cygwin i.e. I was able to call a C++ function from .NET.

Why am I able to do this in Visual C++ and not Cygwin? The code can be found in my linked question. Here is a screen shot of Dependancy Walker for the Visual C++ DLL in case it helps answer my question:

解决方案

Name mangling schemes are different in gcc/mingw/cygwin and msvs. You'll have to use the pure-C interface if you want to share DLLs between compilers.

Alternatively, you could use .def files as is described in the bottom answer to this question: How to use libraries compiled with MingW in MSVC?
