32位DLL具有64位依赖性 [英] 32-bit DLL has 64-bit dependancies

问题描述

大家好，



我用C ++构建了一个DLL，用于C＃应用程序。该DLL是为Win32构建的，但根据Dependency Walker，它具有64位依赖性。我做错了什么？



另外，我认为可以在32位或64位系统上运行的C＃应用​​程序中使用32位DLL ？



谢谢.....

Hi Guys,

I've built a DLL in C++ to use in a C# application. The DLL was built for Win32 but, according to Dependency Walker, it has 64-bit dependancies. What did I do wrong?

Also, am I correct in thinking that a 32-bit DLL can be used from a C# application running on either 32 or 64 bit systems?

Thanks.....

推荐答案

Steve Steve，

我对此很好奇，经过谷歌搜索后，我发现在64位系统上使用32位Dep.walker作为32位二进制文​​件的可能解决方案。否则结果可能会令人困惑。这似乎在例如

干杯，

Hi Steve,
I was curious about this and after googling a bit I found as a possible solution to use a 32-bit Dep.walker for 32-bit binaries on a 64-bit system. Otherwise the results can be confusing. This seems to be explained for example in

没有足够的信息说出你做错了什么。



您需要了解您不能在一个过程中混合使用不同的指令集架构。不仅32位（x86）与64位，但你不能混合不同的64位架构（x86-64（也称为AMD64）和IE-64（Itanium），它们是不同的）。请参阅：

http://en.wikipedia.org/wiki/Instruction_set ，

http://en.wikipedia.org/wiki/X86 ，

http://en.wikipedia.org/wiki/X86-64 ，

http://en.wikipedia.org/wiki/Itanium 。



是的，您可以在64位操作系统上使用32位DLL，但是如何？仅在某些32位进程中。在Windows上，这是通过WoW64完成的： http://en.wikipedia.org/wiki/WoW64 。

Not enough information to say what do you do wrong.

You need to understand that you cannot mix different instruction-set architectures in one process. Not only 32-bit (x86) with 64-bit, but you cannot mix different 64-bit architectures (x86-64 (also known as AMD64) and IE-64 (Itanium), they are different). Please see:
http://en.wikipedia.org/wiki/Instruction_set,
http://en.wikipedia.org/wiki/X86,
http://en.wikipedia.org/wiki/X86-64,
http://en.wikipedia.org/wiki/Itanium.

Yes, you can use 32-bit DLL on a 64-bit OS, but how? Only in some 32-bit processes. On Windows, this is done via WoW64: http://en.wikipedia.org/wiki/WoW64.
