【问题标题】：error LNK2005: xxx already defined in MSVCRT.lib(MSVCR100.dll) C:\something\LIBCMT.lib(setlocal.obj)错误 LNK2005: xxx 已在 MSVCRT.lib(MSVCR100.dll) C:\something\LIBCMT.lib(setlocal.obj) 中定义

【问题描述】：

我正在使用 DCMTK 库来读取 Dicom 文件（医学图像处理中使用的图像格式）。我在编译此 DCMTK 源代码时遇到了问题。 DCMTK 使用了一些额外的外部库（zlib、tiff、libpng、libxml2、libiconv）。我知道所有库都应该使用相同的代码生成选项生成。

我已经下载了这些支持库的编译版本，这些支持库是使用“多线程 DLL”运行时选项 (/MD) 编译的。在 DCMTK 源代码的每个项目中，我确保运行时选项是“多线程 DLL”（/MD）。但我仍然收到这些错误：

编辑：

观察：

只有 LIBCMT.LIB 和 MSVCRT.LIB 之间存在冲突
这两个 LIB 文件在错误中显示的位置不存在。

EDIT2：

是的，问题是因为某些支持库不是使用 /MD 构建的。所以，我自己用 /MD 构建了所有的支持库，我的问题就解决了。

【问题讨论】：

标签： c++ c visual-c++ linker msvcr100.dll

【解决方案1】：

您正在混合使用 /MD（使用 CRT 的 DLL 版本）编译的代码与使用 /MT（使用静态 CRT 库）编译的代码。那行不通，必须使用相同的设置编译所有源代码文件。鉴于您使用使用 /MD 预编译的库，几乎总是正确的设置，您也必须使用此设置编译您自己的代码。

项目 + 属性、C/C++、代码生成、运行时库。

请注意，这些库可能是使用早期版本的 CRT 编译的，msvcr100.dll 是相当新的。不确定这是否会引起麻烦，您可能必须阻止链接器生成清单。您还必须确保将所需的 DLL 部署到目标机器，包括 msvcr100.dll

【讨论】：

我认为您在我的问题中错过了这一点：In each project of DCMTK solution (source code) I ensured that runtime options are "Multithreaded DLL" (/MD). But still I'm getting these errors. 在 DCMTK 解决方案中（大约有 62 个项目）。对于每个项目，我检查了项目+属性、C/C++、代码生成、运行时库设置，它是/MD。即使在此之后，我也会收到此错误。
链接器在争论你的说法，而不是我。当心这些“dcmtk”项目之一使用编译错误的 .lib 本身。
我已经编辑了我的问题。你对我编辑的第二点有什么要评论的吗？
嗯，错误信息中LIBCMT的位置很奇怪，它不属于那里。我唯一的猜测是，链接器实际上是在选择一个预构建的 lib 版本，而不是你自己重建的那个。
"lib 的预构建版本，而不是您自己重建的版本。"我没有构建任何 LIBCMT / MSVCRT。此外，重要的是在提到的任何这些位置都没有 LIBCMT.LIB 或 MSVCRT.LIB。

【解决方案2】：

得到这个错误，我改变了

c/C++ > Code Generation > Runtime Library to Multi-threaded library (DLL) /MD

适用于代码项目和相关的 Google 测试项目。这解决了问题。

注意：项目的所有组件必须具有相同的定义 c/C++ > 代码生成 > 运行时库。 DLL 或非 DLL，但相同。

【解决方案3】：

有些读者会遇到另一个问题，需要此修复。阅读下面的链接。随着 windows sdk 10 的出现，Visual Studio 2015 也出现了同样的问题，它带来了 libucrt。 ucrt 是 C 运行时 (CRT) 又名 posix 运行时库的 Windows 实现。您很可能有从 unix 移植的代码...欢迎来到缺点

【解决方案4】：

如果您的 VS 解决方案包含多个项目，请在右侧窗格中选择所有项目，然后按“属性”。然后转到 C++ -> 代码生成并为所有这些选择一个运行时库选项
