Xcode 4 无法从静态库依赖项中找到公共头文件 [英] Xcode 4 can't locate public header files from static library dependency

问题描述

辅助搜索的替代标题

• Xcode 找不到标题
• Xcode 中缺少 .h
• 未找到 Xcode .h 文件
• 找不到词法或预处理器问题文件

我正在开发一个来自 Xcode 3 的 iOS 应用程序项目.我现在已经转移到 Xcode 4，我的项目构建了许多静态库.

这些静态库还声明公共头文件，并且这些头文件由应用程序代码使用.在 Xcode 3.x 中，标头被复制(作为构建阶段)到 public headers directory，然后在应用程序项目中 public headers directory 被添加到 标题搜索列表.

在 Xcode 4 下，构建目录移动到 ~/Library/Developer/Xcode/DerivedData/my-project.

问题是如何在标题搜索设置中引用这个新位置?看来:

• public headers directory是相对于DerivedData目录的，但是
• headers search 目录相对于其他东西(可能是项目位置)

我应该如何在 Xcode 4 中为 iOS 开发设置一个静态库目标，以确保在尝试编译为依赖项时使用静态库的客户端可以使用头文件?

解决方案

相关问题:词法或预处理器问题文件在 Xcode 4 中找不到"

错误可能包括:缺少头文件、词法或预处理器问题"

解决方案:

1. 检查用户标头路径"；是正确的
2. 设置始终搜索用户路径"是的
3. 创建群呼索引标头"在您的项目中并将标题拖到该组中，请勿在出现提示时添加到任何目标.

Alternate titles to aid search

• Xcode can't find header
• Missing .h in Xcode
• Xcode .h file not found
• lexical or preprocessor issue file not found

I'm working on an iOS application project which came from Xcode 3. I have now moved to Xcode 4 my project builds a number of static libraries.

Those static libraries also declare public headers and those headers are used by the application code. In Xcode 3.x the headers were copied (as a build phase) to the public headers directory, then in the application project the public headers directory was added to the headers search list.

Under Xcode 4 the build directory is moved to ~/Library/Developer/Xcode/DerivedData/my-project.

The problem is how do I reference this new location in the headers search settings? It seems that:

• public headers directory is relative to DerivedData directory, but
• headers search directory is relative to something else (possibly the project location)

How should I set up a static library target for iOS development in Xcode 4 that will ensure the header files are made available to the clients that use the static library when trying to compile as a dependancy?

解决方案

Xcode 4 Project Fails to compile a static library

Related question: "lexical or preprocessor issue file not found " in Xcode 4

Errors might include; missing header files, "lexical or preprocessor issue"

Solutions:

1. Check the "user header paths" are correct
2. Set "Always search user paths" to YES
3. Create a group call "Indexing headers" in your project and drag the headers to this group, DO NOT add to any targets when prompted.
