搜索路径中的相对路径 参考使用 #include 指令编译器的当前目录文件的目录，现在显示一些简单的测试。

Relative paths in the search paths refer to the directory of the file with the #include directive the current directory of the compiler, some simple testing now shows.

.. \ ..从你的头文件升级到编译器的当前目录而不是你的项目目录。

"..\.." is going up two levels from your header file the current directory of the compiler instead of from your project directory.

要解决此问题，请在Visual Studio项目目录中显式启动包含路径，如下所示（字面意思）：

To fix this, explicitly start your include paths in your Visual Studio project directory, as follows (literally):

$（ProjectDir）.. \ ..; $（ProjectDir）.. \..\BoostXXX

$(ProjectDir)..\..;$(ProjectDir)..\..\BoostXXX

关于正斜杠和反斜杠，在C ++代码的 #include 指令中使用正斜杠，因为这是最便携的。

Regarding forward versus backward slash, use forward slash in your C++ code's #include directives, because that's most portable.

使用向前或向后斜杠（但我更喜欢向后斜杠以便有一个转换你指的是Windows文件系统，例如在包含路径的设置中。

Use either forward or backward slash (but I prefer backwards slash so as to have a single convention) where you're referring to the Windows file system, such as in the setup of include paths.
