如何在 lldb 中显示完整的文件名

How to display full file name in lldb

本文关键字：文件名 显示 lldb      更新时间：2023-10-16

我对gdb的基本命令非常熟悉。不幸的是，苹果切换到了lldb，它具有完全不同的命令集，现在我需要学习一个新工具。

尝试调试程序时，我单步进入函数，但它没有显示函数所在的完整文件名。所以没有文件的路径。

是否有检索它的命令？

谢谢。

您可以执行image lookup -n <func-name>来获取文件名

(lldb) image lookup -n main
1 match found in /Users/ml9951/manticore/trunk/src/regression-tests/goals/seq-logging/a.out:
    Address: a.out[0x0000000100027670] (a.out.__TEXT.__text + 156144)
    Summary: a.out`main at main.c:90    <<--------
(lldb)

它没有完整的路径，但希望这对某些人有所帮助。

(lldb) image lookup -v -a $pc
