Xcode:链接终结器时忽略符号警告
提问于 2015-01-22 09:49:57
我在将终结器集成到xcode项目时遇到问题，我得到的警告如下
Warning: Ignored symbols were detected in this build. In some cases ignored symbols could cause incorrect finalization. This may be caused by different static libraries containing the same symbol.
warning: no debug symbols in executable (-arch armv7)还有一长串像这样的列表
Ignored symbol '_int_update' defined at address 0xfb2cc -- it was already defined at 0xd2c94
Ignored symbol '_init' defined at address 0xfcbd8 -- it was already defined at 0xfcba4
Ignored symbol '_update' defined at address 0xfcbe4 -- it was already defined at 0xfcbb0
Ignored symbol '_final' defined at address 0xfcbf0 -- it was already defined at 0xfcbbc如有任何帮助或建议，将不胜感激。

如果在所有具有相同名称的可重定位目标文件中定义了2个或更多个符号，则链接器将选择其中一个，而忽略其他符号。
如果这些符号具有不同的类型，则可能会在运行时导致无法理解的错误。
在Computer Systems_A Programmer-'s Perspective的第7章中有一个例子
