xcode – 如何通过OS X上的系统库进行调试？

概述我正在调试一个调用系统库的 Cocoa应用程序.我为自己的代码获取调试符号,但不是系统库,这使我无法进一步调试.如何获取系统库的调试符号. 我正在使用gdb,在10.6.4(gcc 4.2)上针对10.5 SDK进行编译. 这是我希望获得符号的堆栈跟踪： (gdb) bt#0 0x93713e43 in CFQSortArray ()#1 0x936f4c49 in CFArraySort 我正在调试一个调用系统库的 Cocoa应用程序.我为自己的代码获取调试符号,但不是系统库,这使我无法进一步调试.如何获取系统库的调试符号.

我正在使用gdb,在10.6.4(gcc 4.2)上针对10.5 SDK进行编译.

这是我希望获得符号的堆栈跟踪：

解决方法 如本苹果技术说明中所述,您希望将DYLD_IMAGE_SUFFIX设置为_deBUG.

还有其他问题(在正确的系统上没有正确的版本)很难克服,所以我没有测试过.
