C ++ DLL导出：Decorated / Mangled名称 [英] C++ DLL Export: Decorated/Mangled names
问题描述
使用模块定义文件（MyDLL.def）创建基本C ++ DLL和导出的名称。
编译之后，我使用 dumpbin.exe检查导出的函数名称。
我希望看到：
Created basic C++ DLL and exported names using Module Definition file (MyDLL.def).
After compilation I check the exported function names using dumpbin.exe
I expect to see:
SomeFunction
p>
but I see this instead:
SomeFunction = SomeFunction@@@23mangledstuff#@@@@
为什么？
导出的函数出现无装饰（特别是与不使用Module Def文件相比）与其他东西？
The exported function appears undecorated (especially compared to not using the Module Def file), but what's up with the other stuff?
如果我使用 dumpbin.exe 从任何商业应用程序的DLL，你会得到清洁：
If I use dumpbin.exe against a DLL from any commercial application, you get the clean:
SomeFunction
而没有别的...
我也尝试删除模块定义并使用C导出样式导出名称，即：
I also tried removing the Module Definition and exporting the names using the "C" style of export, namely:
extern "C" void __declspec(dllexport) SomeFunction();
（仅使用externC未创建导出函数）
(Simply using "extern "C" did not create an exported function)
但是，这仍然创建相同的输出，即：
However, this still creates the same output, namely:
SomeFunction = SomeFunction@@@23mangledstuff#@@@@
我还尝试了 #define dllexport __declspec dllexport）选项，并创建了一个没有问题的LIB。但是，我不想在C＃应用程序中为使用DLL的人提供LIB文件。
I also tried the #define dllexport __declspec(dllexport) option and created a LIB with no problem. However, I don't want to have to provide a LIB file to people using the DLL in their C# application.
这是一个简单的C ++ DLL（非托管代码），用C ++编译只有一个简单的头和代码。没有模块定义我得到错误的导出函数（我可以创建一个静态库和使用LIB没有问题如果我使用 externC__declspec（dllexport） 或模块定义我得到什么出现是一个未装饰的函数名...唯一的问题是它后面是一个=和什么看起来像功能的装饰版本。我想摆脱=后的东西 - 或至少理解为什么它在那里。
It's a plain vanilla C++ DLL (unmanaged code), compiled with C++ nothing but a simple header and code. Without Module Def I get mangled exported functions (I can create a static library and use the LIB no problem. I'm trying to avoid that). If I use extern "C" __declspec(dllexport) OR a Module Definition I get what appears to be an undecorated function name... the only problem is that it is followed by an "=" and what looks like a decorated version of the function. I want to get rid of the stuff after the "=" - or at least understand why it is there.
按照原样，我可以肯定的是，我可以使用P / Invoke从C＃调用函数...我只是想避免那个垃圾在结束的=。
As it stands, I'm pretty certain that I can call the function from C# using a P/Invoke... I just want to avoid that junk at the end of the "=".
我打开了关于如何更改项目/编译器设置的建议，但我只是使用标准的Visual Studio DLL模板 - 没有什么特别的。
I'm open to suggestions on how to change the project/compiler settings, but I just used the standard Visual Studio DLL template - nothing special.
推荐答案
您可以通过关闭调试信息生成来获得所需的内容。项目+属性，链接器，调试，生成调试信息=
You can get what you want by turning off debug info generation. Project + Properties, Linker, Debugging, Generate Debug Info = No.
当然，您只想为发布版本执行此操作。其中选项已经设置了这种方式。
Naturally, you only want to do this for the Release build. Where the option is already set that way.
