如何为xcode添加全局包含路径 [英] How to add a global include path for xcode

问题描述

我想在使用Xcode时添加〜/ include到所有项目的包含路径，比如设置环境变量 CPLUS_INCLUDE_PATH 在Linux中。 （有关相关内容，请参见此处 Linux问题。）

I'd like to add ~/include to my include path for all projects while using Xcode, something like setting the environment variable CPLUS_INCLUDE_PATH in Linux. (See here for the related Linux question.)

这在Xcode中是否可行？我尝试设置上面的环境变量，但它似乎不起作用。 （如果有可能，我还想设置相关的路径，比如LIBRARY_PATH和LD_LIBRARY_PATH。）

Is this possible in Xcode? I tried setting the above environment variable, but it doesn't seem to work. (And if it is possible, I'd like to also set related paths, like LIBRARY_PATH and LD_LIBRARY_PATH.)

推荐答案

根据 Apple's文档，您可以使用环境变量为任何构建设置提供默认值。

在这种情况下，您需要设置 HEADER_SEARCH_PATHS 。由于某些原因我不明白，这不起作用。它适用于其他构建设置（例如，OTHER_CFLAGS），但不适用于 HEADER_SEARCH_PATHS 。您可以通过在构建设置窗口（左下方的书籍按钮）中打开研究助手来查看任何设置的变量名称。

In this case, you'd want to set HEADER_SEARCH_PATHS. For some reason I don't understand, this doesn't work. It works fine for other build settings (for example, OTHER_CFLAGS), but not for HEADER_SEARCH_PATHS. You can see what the variable name for any setting is by opening the research assistant in the build settings window (book button on the bottom left.)

一个可以工作的var是 USER_HEADER_SEARCH_PATHS ，这与您想要的一样，但仅适用于双引号中的路径（不在尖括号中）。

One var that does work is USER_HEADER_SEARCH_PATHS, which is just like what you want, but only works for paths in double quotes (not in angle brackets.)

所以

#include "bar.h"

可行，但

#include <bar.h>

不会。

构建从上面关于环境变量的文章中引用的设置plist最终应该看起来像这样：

The build settings plist referenced from the above article on environment variables should end up looking something like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>USER_HEADER_SEARCH_PATHS</key>
    <string>~/test</string>
</dict>
</plist>
