如何链接到VS2008从g ++生成的.libs [英] How to link to VS2008 generated .libs from g++

问题描述

我有.h文件，它指向由MS使用MS生成的.dll导出的对象。 Visual Studio 2008.我链接到用.dll生成的.lib。

当我运行g ++时，我得到了很多像这样的错误

  /cygdrive/c/dev/blox/ulfx/ulfx/JavaInterface.cpp:206：对__imp___ZNK18DLLSafeDoubleArray4sizeEv'
  

我想链接到的.dll公开一个名为

的函数

pre > ？size @ DLLSafeDoubleArray @@ QBEIXZ


我假设这里的问题是g ++名称mangling与VS2008 name mangling不兼容。

有没有办法让g ++可以使用兼容的mangling？

我没有安装任何版本的Visual Studio。

由不同的 C ++ 编译器是不兼容的。

这是有意完成的 ：编译器使用不同的ABI，如果名称混淆并不妨碍你连接，你现在想知道/调试为什么最简单的操作会导致你的可执行文件崩溃。

你应该感激不同的名称修改方案免除了您的调试工作。

I am trying to build a dll using mingw g++ under cygwin.

I have .h files that refer to objects exported by a .dll that was build using MS Visual Studio 2008. I link to the .lib generated with that .dll.

When I run g++ I get lots of errors like this

/cygdrive/c/dev/blox/ulfx/ulfx/JavaInterface.cpp:206: undefined reference to `__imp___ZNK18DLLSafeDoubleArray4sizeEv'

The .dll that I want to link to exposes a function named

?size@DLLSafeDoubleArray@@QBEIXZ

And I assume that the problem here is that the g++ name mangling is incompatible with the VS2008 name mangling.

Is there a way I can force g++ to use a compatible mangling ?

I do not have any version of Visual Studio installed on my machine.

解决方案

Object code produced by different C++ compilers is not link compatible.

This is done on purpose: compilers use different ABI, and if the name maingling didn't prevent you from linking, you'd now be wondering/debugging why the simplest operations are causing your executable to crash.

You should be grateful that the different name mangling scheme spared you that debugging effort.
