链接错误试图链接的刺激时，文件系统::调试MSVC11项目 [英] Linker errors when attempting to link boost::filesystem to debug MSVC11 project

问题描述

我试图在我的项目中使用的boost ::文件系统，但我碰到的链接错误：

I'm attempting to use boost::filesystem in my project, but I've run into linker errors:

我建设提升用下面的命令：

I am building boost with the following commands:

bootstrap
.\b2

和我指着 $ BOOSTDIR \\阶段\\ lib中的库包括目录，我的编译器是的Visual Studio 2012（V110）。

And I am pointing to $BOOSTDIR\stage\lib for the library include directory and my compiler is Visual Studio 2012 (v110).

我直接尝试连接的调试是在 $ BOOSTDIR \\产生的lib \\ * 目录库，但跑进其他错误。我还怀疑是不是静态链接库的标准或预期的方式。

I have tried directly linking the debug libraries that are generated in the $BOOSTDIR\lib\* directories but ran into other errors. I also suspect that that is not the standard or intended way to statically link the libraries.

我在做什么错在这里？

推荐答案

您正在混合使用C运行时库的联系和调试/释放二进制文件。

You're mixing both C runtime library linkages and debug/release binaries.

libcmt 是静态C运行时库的发行版本，而 msvcrtd 是动态的调试版本C运行时库。您同时显示在你的错误，这意味着你要他们混，你不能做。

libcmt is the release version of the static C runtime library, while msvcrtd is the debug version of the dynamic C runtime library. You have both showing up in your errors, meaning that you're trying to mix them, which you can't do.

您需要重建加速使用C运行时的相同版本的项目或重建项目中使用相同版本的加速。然而，事实上，你目前拥有的调试和发行库混合通常是一个标志，别的东西是真的错了您的设置。

You need to rebuild Boost to use the same version of the C runtime as your project, or rebuild your project to use the same version as Boost. However, the fact that you currently have debug and release libraries mixed is usually a sign that something else is really wrong with your settings.

如果您在项目中的属性看，转到C / C ++ - > code一代，你会看到一个运行时库字段。您可以将其更改为指定项目应该如何链接到C运行时。 / MDD将链接 msvcrtd.dll ，而/ MT将链接 LIBCMT.LIB 。

If you look in your project's properties and go to C/C++ -> Code Generation, you'll see a 'Runtime Library' field. You can change this to specify how your project should link to the C runtime. /MDd will link msvcrtd.dll, while /MT will link libcmt.lib.
