重复符号链接器错误 XCode 3.2.5 - 链接器似乎以不同方式引用同一文件

Question

我收到以下错误：

ld：重复符号 /Users/macuser/Dropbox/DFJ/third20/Build/Products/Debug-iphoneos/libThree20Core.a(TTGlobalCore.o) 中的 _TTCreateNonRetainingArray 和 ../two20/Build/Products/Debug-iphoneos/libThree20Core.a(TTGlobalCore.o) Collect2: ld 返回 1 退出状态 命令 /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++-4.2 失败，退出代码为 1

它似乎从绝对和相对路径引用相同的 .o 。

请在此处查看 Three20 开发者的最后一条消息。基本上，下载最新的 Three20 源代码并严格按照其 README。

如果您正在遵循的 Three20 教程不是来自开发人员，那么它很可能已经过时了。
