找不到C ++ Boost文件 [英] C++ Boost not found file

问题描述

我正在尝试使用boost中的variant，并且收到此错误:

I'm trying to use variant from boost and I'm receiving this error:

严重错误C1083:无法打开包含文件:'boost/variant.hpp':否 这样的文件或目录

fatal error C1083: Cannot open include file: 'boost/variant.hpp': No such file or directory

我已将文件包含在项目属性中.

I've included the files in project properties.

在参考目录和图书馆目录中，我也尝试过使用

In the Reference Directories and Library Directories I've tried also with

• "... \ lib"
• ".... \ stage \ lib"

我还在包含目录中尝试过:

• "... \ boost_1_68_0"
• "... \ boost_1_68_0 \ boost"

在一开始，我使用了 D:\ Libs \ boost_1_68_0 \ libs ，并且因为它不起作用，所以我编译了boost并尝试使用<之后，strong> D:\ Libs \ boost_1_68_0 \ stage \ lib .

In the beginning, I used D:\Libs\boost_1_68_0\libs and because it didn't work I've compiled boost and I've tried with D:\Libs\boost_1_68_0\stage\lib after that.

但是没有成功.

此外，我应该说我在VisualStudio2010和2015年都曾尝试过此方法，并且我遵循了

Also, I should say that I've tried this in VisualStudio2010 and also in 2015 and I've followed this tutorial.

对我有解决方案吗?感谢您的建议:)

Any solution for me? Thanks in advice :)

推荐答案

您已将include设置为D:\Libs\boost_1_68_0\boost.但是代码中的include看起来像<boost/variant.hpp>.因此，如果您将include设置为D:\Libs\boost_1_68_0，则<boost/whatever/...>将从此开始.

You have set your include to D:\Libs\boost_1_68_0\boost. But the includes in your code will look like <boost/variant.hpp>. So if you set your include, instead, to D:\Libs\boost_1_68_0 then the <boost/whatever/...> will follow from there.

您真正应该做的是将一个名为BOOST_ROOT的环境变量设置为D:\Libs\boost_1_68_0.然后在项目集中添加$(BOOST_ROOT)的其他内容.请注意，必须重新启动Visual Studio才能使环境更改生效.

What you really should do is set an environment variable called BOOST_ROOT to D:\Libs\boost_1_68_0. Then in your project set additional includes with $(BOOST_ROOT) Note that you have to restart Visual Studio for the environment change to take effect.

现在，将来boost_1_69出现时，您可以将其放置在所需的位置，并且在更新环境变量时，将使用以前使用过$(BOOST_ROOT)的所有项目.

Now in the future, when boost_1_69 comes out, you can put it where ever you would like and all the previous projects where you have used $(BOOST_ROOT) will follow when you up date the environment variable.

总是在/stage/lib中构建您的boost库，这是b2构建器的默认库.对于其他库，请使用$(BOOST_ROOT)/stage/lib

Always build your boost lib in /stage/lib, it is the default for the b2 builder. And for your additional libs use $(BOOST_ROOT)/stage/lib
