visual studio 2010包括目录路径 [英] visual studio 2010 include directory paths

问题描述

我有一个visual studio解决方案myvs.sln，其路径如下： c：\dir1 \dir2 \dir3 \ myvs \ myvs \ myvs.sln 。我在 c：\dir1 \dir2 \dir3 \ boostxxx \ 中安装了升级版xxx。

I have a visual studio solution myvs.sln with the following path: c:\dir1\dir2\dir3\myvs\myvs\myvs.sln. I have boost version xxx installed in c:\dir1\dir2\dir3\boostxxx\.

我在项目中 - > properties-> c / c ++ - > general： ../..;../../ boostxxx 。在boost文件库中，包含文件具有以下语法： #include< boost / smart_ptr / shared_ptr> 。

I have in the project->properties->c/c++->general: ../..;../../boostxxx. Inside boost libraries the include files have the following syntax: #include <boost/smart_ptr/shared_ptr>.

我的代码文件 myfile.h 位于 c：\dir1 \dir2 \dir3\yy1\myfile.h 。在myfile.h中，我将boost库包含在： #include< boost / shared_ptr.hpp> 。我收到一条错误，上面写着： c：\dir1 \dir2 \dir3 \yyy1 / myfile.h致命错误C1083无法打开包含文件boost / shared_ptr.hpp 。

My code file myfile.h resides in c:\dir1\dir2\dir3\yy1\myfile.h. In myfile.h I include boost libraries as: #include <boost/shared_ptr.hpp>. I am getting a error which says: c:\dir1\dir2\dir3\yyy1/myfile.h fatal error C1083 cannot open include file boost/shared_ptr.hpp.

问题是我应该怎么做才能纠正这个问题？

The question is what should I do to correct this?

我还注意到错误输出了编译器投掷有\到dir3然后更改为/\".

I also notice that the error output the compiler throws has "\" upto dir3 and then changes to "/".

我很可能不明白相对路径是如何工作的。另请注意，我只想引用相对路径而不是绝对路径。有人可以帮忙吗？我在Windows平台上使用c ++ visual studio 2010。

Most probably I do not understand how the relative path is working. Also note that I want to refer to only relative path not absolute paths. Can someone please help? I am in windows platform using c++ visual studio 2010.

推荐答案

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.
