我收到以下错误：
ld：重复的符号 _TTCreateNonRetainingArray in /Users/macuser/Dropbox/DFJ/three20/Build/Products/Debug-iphoneos/libThree20Core.a(TTGlobalCore.o） 和 ../three20/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 退出代码1失败
它似乎是指绝对和相对路径中的相同.o。
