如何使用“用户标头搜索路径”使 Xcode 正确找到标头？

我正在尝试使用 Xcode 从 libFLAC 构建一个框架，以便在我自己的 Mac OS X 应用程序中使用。

我使用这些 FLAC 源：

http://sourceforge.net/projects/flac/files/flac-src/flac-1.2.1-src/flac-1.2.1.tar.gz/download

我只需要一个这些源文件很少，但我宁愿保持所有内容不变，这样如果我想用我自己的源代码分发框架项目，我就可以保留原始的 FLAC 源代码。

flac-1.2.1.tar.gz 包含以下目录：

flac-1.2.1/include/
flac-1.2.1/src/libFLAC/
flac-1.2.1/src/libFLAC/include/

为了构建 libFLAC，我已将“flac-1.2.1/src/libFLAC”中的 .c 文件添加到项目中（作为参考）。我还添加了 .h 文件。

源代码中使用的标头位于：

flac-1.2.1/include/FLAC/
flac-1.2.1/include/share/
flac-1.2.1/src/libFLAC/private/

例如，标头的源代码调用是：

#include "private/bitmath.h"
#include "FLAC/assert.h"
#include "private/bitwriter.h"
#include "private/crc.h"
#include "share/alloc.h"

等。

在 Xcode 中，我已将这些“用户标头搜索路径”添加到目标构建设置中：

$(SRCROOT)/flac-1.2.1/include/
$(SRCROOT)/flac-1.2.1/src/libFLAC/include/

当然，我已将我的 flac-1.2.1 目录放在正确的位置。

当我想编译时，编译器找不到头文件。我尝试使用 GCC 4.2 和 LLVM 编译器 2.0。我做错了什么？我应该做更多的事情吗？

我是在我的全 ObjC 项目中导入 C 源代码的新手，我很乐意尝试您向我提供的任何内容。只是请避免回答“如果你做不到，你就不应该这样做”。我需要学习这个并且我会的。

I'm trying to build a framework from libFLAC with Xcode, to use within my own Mac OS X application.

I use these FLAC sources:

http://sourceforge.net/projects/flac/files/flac-src/flac-1.2.1-src/flac-1.2.1.tar.gz/download

I only need a few of these source files but I'd rather keep everything untouched so I'm able to keep the original FLAC source if I want to I distribute the framework project with my own sources.

The flac-1.2.1.tar.gz contains these directories:

flac-1.2.1/include/
flac-1.2.1/src/libFLAC/
flac-1.2.1/src/libFLAC/include/

In order to build libFLAC, I've added the .c files from 'flac-1.2.1/src/libFLAC' into the project (as references). I also added the .h files.

The headers used in the source code are located in:

flac-1.2.1/include/FLAC/
flac-1.2.1/include/share/
flac-1.2.1/src/libFLAC/private/

For instance the sources code calls for the header are:

#include "private/bitmath.h"
#include "FLAC/assert.h"
#include "private/bitwriter.h"
#include "private/crc.h"
#include "share/alloc.h"

etc.

In Xcode, I've added these 'User Header Search Paths' to the the target Build Settings:

$(SRCROOT)/flac-1.2.1/include/
$(SRCROOT)/flac-1.2.1/src/libFLAC/include/

And of course, I've placed my flac-1.2.1 directory in the right place.

When I want to compile, the compiler doesn't find the headers file. I tried with GCC 4.2 and LLVM compiler 2.0. What am I doing wrong? Should I do something more?

I'm new into importing C sources in my otherwise all-ObjC project and I'd be happy to try whatever you throw at me. Just please avoid answering "If you can't do it, you shouldn't do it". I need to learn this and I will.
