我正在从Xcode 3.5迁移到Xcode 4，
当我尝试将我的应用存档以进行AdHoc分发时。
我收到此错误

你知道我应该怎么做才能解决这个问题吗？
更新(遵循MacMade的建议后的报告结果)
因此，在目标构 build 置中:
中没有任何其他C标志。
用户头搜索路径中没有任何内容
在 header 搜索路径中，我具有:
”$(BUILT_PRODUCTS_DIR)/../three20″ “$(BUILT_PRODUCTS_DIR)/../../three20″ ./three20/Build/Products/three20 /usr/include/libxml2 但我不确定在这里要更改什么。
在C/C++/Objective-C 设置的编译器中，
我从
Apple LLVM compiler 切换到 LLVM GCC 并收到以下消息: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
更新(遵循MacMade的更新建议后的报告结果)
所以我移动:
”$(BUILT_PRODUCTS_DIR)/../three20″ “$(BUILT_PRODUCTS_DIR)/../../three20″ 到用户标题搜索路径
它有效!!!
(注意:我不会移动。/three20/Build/Products/three20，因为我看到了
can't find <Three20/Three20.h>如果我这样做，则在构建项目时出错。) 最佳答案
显然，您已经为include路径设置了自定义编译器标志。
转到目标的构 build 置，然后检查以下选项:
如果其中包含某些内容，则可以将其替换为
-iquote版本。否则，仍在构 build 置中，检查以下选项的值:
尝试操纵这些值(如果适用)。
否则，您也可以继续使用GCC代替Clang。
您可以通过将C/C++/Objective-C的编译器构 build 置设置为 LLVM GCC 而不是 Apple LLVM编译器来实现。
编辑
根据您的编辑，我可以看到您正在使用Three20库。
根据您包含这些内容的方式，您可能希望将这些搜索路径放入用户标题搜索路径，而不是标题搜索路径(如果将它们包括在
""而不是<>中)。尝试为Three20执行此操作，但在此处保留libxml ...
