setenv PATH "/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin"

未定义的符号：

  "_OBJC_CLASS_$_RMDBMapSource", referenced from:
      objc-class-ref-to-RMDBMapSource in cloudmade2ViewController.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

我该如何解决这个问题？我尝试环顾四周，但没有找到如何解决该问题的答案。

您的目标不包含用于编译源的 RMDBMapSource.m 以及可能更多的文件。检查您是否已包含从route-me 项目到目标的所有文件。
