-Wmissing-include-dirs和自动包含的头目录

When building a project in Xcode (3.1.2), 2 folders are automatically added as header directories with the '-I' option:

在Xcode(3.1.2)中构建项目时,会自动将2个文件夹添加为带有'-I'选项的头目录:

/ (ProjPath) / (ProjName) / build / (BuildConfigName) / include  
/ (ProjPath) / (ProjName) / build / (ProjName).build / (BuildConfigName) / (ProjName).build / DerivedSources

I realized this when trying to add -Wmissing-include-dirs to the warnings list in my project. A warning is emitted for both folders. This happens for both Cocoa Applications and C++ Dynamic Libraries. I haven't tried any other project type, but I suppose this behavior applies to any project type.

我在尝试将-Wmissing-include-dirs添加到项目中的警告列表时意识到了这一点。两个文件夹都会发出警告。 Cocoa应用程序和C ++动态库都会发生这种情况。我没有尝试过任何其他项目类型,但我认为这种行为适用于任何项目类型。

How are these folders used by Xcode?

这些文件夹是如何被Xcode使用的?

Can they be either avoided, or automatically created by Xcode when build begins?

它们可以避免,还是在构建开始时由Xcode自动创建?

If not, how to successfully use -Wmissing-include-dirs with Xcode?

如果没有,如何成功使用-Wmissing-include-dirs与Xcode?

Thanks.

You can add a script to your target which creates the directories for your:

您可以向目标添加脚本,为您创建目录:

Right-click your target, select Add -> New Build Phase -> New Run Script Build Phase. Drag this build phase to the top of your target, before the "Compile Sources" phase.

右键单击目标,选择Add - > New Build Phase - > New Run Script Build Phase。在“编译源”阶段之前,将此构建阶段拖到目标的顶部。

Then enter a script like this (by double-clicking the phase):

然后输入这样的脚本(通过双击阶段):

mkdir -p "${TARGET_BUILD_DIR}/include"
mkdir -p "${PROJECT_DERIVED_FILE_DIR}"

You can see the various environment variables in the build transcript (Command-Shift-B, click the little text icon, drag the build transcript up.)

您可以在构建脚本中看到各种环境变量(Command-Shift-B,单击小文本图标,向上拖动构建脚本。)
