Boost库无法在C ++中工作，包含目录不起作用 [英] Boost Library cannot get to work in C++, Include directories not working

问题描述

我最近尝试在C ++ 14中安装Boost库，并添加了它的包含路径，如:

I recently tried to install boost libraries in C++ 14, and I added it's include paths like:

解决方案资源管理器>项目名称>属性页> VC ++目录>"C:\ Program Files(x86)\ Microsoft Visual Studio 14.0 \ boost \ boost"

添加此代码后，我尝试进行编译:

I tried to compile after adding this:

#include <boost\variant.hpp>

在错误列表"窗口中，我可以看到E1696 - cannot open source file "boost\variant.hpp"，并且无法像以前那样进行编译.

In Error List window, I can see E1696 - cannot open source file "boost\variant.hpp" and I can't compile like before.

然后，我尝试添加反斜杠，例如"C:\ Program Files(x86)\ Microsoft Visual Studio 14.0 \ boost \ boost \" ，仍然无法正常工作.

Then I tried with adding a backslash like "C:\Program Files (x86)\Microsoft Visual Studio 14.0\boost\boost\", still didn't work.

我还阅读了此发布并明确指定它的目录，但甚至不起作用.

I also read this post and explicitly specified it's directory, but even didn't work.

再次，我阅读了这篇帖子，其内容完全相同给定答案(因为我已经多次构建项目)，但仍然没有成功.

Again, I read this post and did exactly same what is in given answer (as I already built project several times) , but still no success.

但是，如果我包括一个像这样的图书馆:

However, if I include a library like:

#include "C:\Program Files (x86)\Microsoft Visual Studio 14.0\boost\boost\variant.hpp"

现在编译器可以识别它，但是现在我可以在错误列表"窗口中看到100多个错误，这些错误是指向boost库的头文件的，而不是包含在我的包含variant.hpp的项目文件中.

Now compiler recognizes it, but now I can see more than 100 errors in Error List window, those errors are pointed to header files of boost libraries, not in my project file which has variant.hpp included.

所有这些错误是E1696 - cannot open source file "boost\<libraryname.hpp>"或E1696 - cannot open source file "boost\<subdirs>\<some other files included in libraryname.hpp>"

因此，如果我从项目的头文件中删除行#include "C:\Program Files (x86)\Microsoft Visual Studio 14.0\boost\boost\variant.hpp"，则所有错误突然消失并且项目编译正常！现在没有任何错误！

So, if I remove the line #include "C:\Program Files (x86)\Microsoft Visual Studio 14.0\boost\boost\variant.hpp" from my project's header file, all errors disappear suddenly and project compiles fine! no any single error now!

无论如何我都希望Boost能够工作，所以我可以在项目中使用它，但是我不能手动编辑所有这些头文件并将<boost\...更改为原始位置.

I want boost to work anyway, so I can use it in projects, but I can't manually edit all those header files and change <boost\... to original locations.

请帮助我摆脱这个问题.

Please help me to get rid of this issue.

推荐答案

• 请确保您下载并安装了正确的Boost版本.可以在Visual Studio目录中安装它，但不建议这样做.我建议您使用此处中的软件包之一.假设您使用Visual Studio 2017 和，并且正在为64位开发
  • make sure you download and install the correct boost version. Installing it in the visual studio directories is possible, but not advised. I suggest you use one of the packages from here. Assuming you use visual studio 2017 and you are developing for 64bit, this could perhaps be the correct package for you.
  • make sure you do both: adding the include search path and the library search path to your visual studio.

  include搜索路径应指向boost-installation根目录(包含Jamroot文件和boost子目录的目录).库搜索路径应指向boost安装中正确的库子文件夹.这是从lib64-msvc-**.*开头的子文件夹之一(如果您正在开发32bit，则为lib32-msvc-*).

  The include search path should point to the boost-installation root directory (the one that contains the Jamroot file and a boost subdirectory). The library search path should point to the correct library subfolder within the boost installation. This is one of the subfolders that start with lib64-msvc-**.* (or lib32-msvc-* if you're developing for 32bit).

  上面的二进制boost软件包的默认安装路径会将其安装到C:\local\boost_<boost version>中.确保使用此安装目录中的路径，并按照说明此处进行操作.

  The default install path of the binary boost package above will install it into C:\local\boost_<boost version>. Make sure you use the paths from this installation directory and follow the instructions here.

  示例:

  包含搜索路径:C:\local\boost_1_64_0

  库搜索路径:C:\local\boost_1_64_0\lib64-msvc-14.1
