我收到以下错误：
ld：在 /Users/macuser/Dropbox/DFJ/three20/Build/Products/Debug-iphoneos/libThree20Core.a(TTGlobalCore.o) 和 ../three20/Build/Products/Debug-iphoneos/libThree20Core.a 中重复符号 _TTCreateNonRetainingArray （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1
它似乎是从绝对路径和相对路径引用相同的 .o 。
