【问题描述】：

我正在尝试使用gdb 调试程序。问题是没有出现日志文件。我是否需要以特定方式退出 gdb-session 或可能出现什么问题？

从gdb 开始并显示日志设置会给出：

问题是没有出现日志文件

您没有启用日志记录，请使用set logging on 启用它：

(gdb) set logging on
Copying output to gdb.txt.
(gdb) show logging
Currently logging to "gdb.txt".
Logs will be appended to the log file.
Output will be logged and displayed.

谢谢。我只是假设“未来的日志将被写入 gdb.txt”意味着会被记录。
