新手：确定库使用的 CRT 库
我正在使用 VC++ 6 开发应用程序。
我有一个第三方 DLL。该库编译为多线程 DLL (/MD)，我的应用程序也是如此。 但我无法链接：
LINK : warning LNK4075: ignoring /EDITANDCONTINUE due to /INCREMENTAL:NO specification
msvcprtd.lib(MSVCP60D.dll) : error LNK2005: "public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::~basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(void)" (??1?$basic_strin
g@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@XZ) already defined in XXXApi.lib(CODbg.obj)
msvcprtd.lib(MSVCP60D.dll) : error LNK2005: "public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(class std::basic_string<c
har,struct std::char_traits<char>,class std::allocator<char> > const &)" (??0?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@ABV01@@Z) already defined in XXXApi.lib(Dictionary.obj)
../../Exes/win2k3_oracle11/XXX.exe : fatal error LNK1169: one or more multiply defined symbols found
Error executing link.exe.
从 here 我看到，即使第三个库和我的代码都已编译作为 /MD，可能与正在使用的旧/新 iostream 发生冲突。
有没有办法确定 3rd 方库使用哪个 iostream 库旧/新？
UPD： 第 3 方库是静态的，而不是我之前认为的动态的。 该库编译为 /MD。 Dependency Walker 与 DLL 一起工作，而不是与哪些库一起工作。
I'm developing application using VC++ 6.
I have a 3rd party DLL. This library compiled as Multithreaded DLL (/MD) and my application too.
But I fail to link:
LINK : warning LNK4075: ignoring /EDITANDCONTINUE due to /INCREMENTAL:NO specification
msvcprtd.lib(MSVCP60D.dll) : error LNK2005: "public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::~basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(void)" (??1?$basic_strin
g@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@XZ) already defined in XXXApi.lib(CODbg.obj)
msvcprtd.lib(MSVCP60D.dll) : error LNK2005: "public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(class std::basic_string<c

../../Exes/win2k3_oracle11/XXX.exe : fatal error LNK1169: one or more multiply defined symbols found
Error executing link.exe.
From here I see that even though both 3rd library and my code compiled as /MD, there's possibly conflict with old/new iostream beining used.
Is there way to determinate what iostream library old/new is used by 3rd party library?
UPD:
The 3rd party lib is static and not dynamic as I thought before.
The lib is compiled /MD. Dependency Walker works wirh DLLs and not which Libs.

如果您不知道这个工具，则有依赖项 Walker。
http://dependencywalker.com/
将 DLL 或 exe 拖放到主窗口上。它将显示所有依赖项。
如果您想链接到第 3 方 DLL，您只需要为该 DLL 制作一个 .lib。
如果您没有该 .lib，您始终可以使用pelles c 工具中的 lib.exe 或 polib.exe 制作一个。
polib 更容易使用，因为您不需要编写 .def 文件。

我希望它对您的问题有所帮助。
编辑：您有正在使用的 .lib 的源代码吗？
There is dependency Walker, if you don't know this tool.
http://dependencywalker.com/
Drag and drop your DLL or exe on the main window. It will show all dependencies.
And if you want to link to a 3rd party DLL, all you need is a .lib made for that DLL.
If you don't have that .lib, you can always make one using lib.exe or polib.exe from pelles c tools.
polib is easier to use because you don't need to write a .def file.

I hope it helps for your question.
Edit: Do you have the source code for the .lib you are using?
