iphone - Xcode 4 - clang 错误

Question

我正在从 Xcode 3.5 迁移到 Xcode 4 并且 当我尝试存档我的应​​用以进行临时分发时。
我收到这个错误

预编译 MyApp_Prefix.pch

**clang: error: '-I-' not supported, please use -iquote instead**
**Command /Xcode4.2/Platforms/iPhoneOS.platform/Developer/usr/bin/clang failed with exit code 1**

你知道我应该怎么做才能解决这个问题吗？

更新(按照 MacMade 的建议报告结果)

所以在目标build设置中:
Other C flags 我什么都没有。
User Header Search Paths

中没有任何内容

在标题搜索路径中，我有:

• ”$(BUILT_PRODUCTS_DIR)/../three20″
• “$(BUILT_PRODUCTS_DIR)/../../three20″
• ./three20/Build/Products/three20
• /usr/include/libxml2

但我不确定要在这里更改什么。

在 Compiler for C/C++/Objective-C 设置中， 我从 Apple LLVM compiler 切换 到 LLVM GCC 并收到此消息:

cc1obj: note: obsolete option -I- used, please use -iquote instead  
cc1obj: error: -I- specified twice  
cc1obj: note: obsolete option -I- used, please use -iquote instead

UPDATE(按照MacMade的更新建议报告结果)

所以我移动:

• ”$(BUILT_PRODUCTS_DIR)/../three20″
• “$(BUILT_PRODUCTS_DIR)/../../three20″

到用户 header 搜索路径

而且有效!!!
(注意:我没有移动 ./three20/Build/Products/three20 因为我看到了
can't find <Three20/Three20.h>
如果我这样做的话，在构建项目时会出错。)

Answer 1

显然，您已经为包含路径设置了自定义编译器标志。

转到目标的build设置并选中此选项:

• 其他 cflags

如果里面有东西，你可以用-iquote代替它版本。

否则，仍然在build设置中，检查以下选项的值:

• header 搜索路径
• 用户 header 搜索路径

尝试操纵这些值(如果适用)。

否则，您也可以继续使用 GCC 作为前端，而不是 Clang。

您可以通过将 Compiler for C/C++/Objective-C build设置设置为 LLVM GCC 而不是 Apple LLVM compiler 来实现此目的.

编辑

根据您的编辑，我可以看出您正在使用 Three20 库。

根据您如何包含这些内容，您可能希望将这些搜索路径放入User Header Search Paths，而不是Header search paths(如果您包含它们使用 "" 而不是 <> )。
尝试为 Three20 执行此操作，但将 libxml 留在这里...
