GDB 打印到文件而不是标准输出 [英] GDB print to file instead of stdout

问题描述

我正在运行 GDB 并想检查那些不幸的上帝对象之一.需要很多页(我有一个 24 英寸的显示器横过来！)才能看到整个事情.

I am running GDB and want to examine one of those unfortunate god objects. It takes many pages (and I have a 24" monitor turned sideways!) to see the whole thing.

为了便于使用，我希望 GDB 将对象打印到文件而不是屏幕，以便我可以在 vi 中打开它并轻松移动.

For ease of use, I'd like GDB to print the object to a file instead of the screen so that I can open it in vi and move around with ease.

凭借 GDB 的所有功能，一定有办法做到这一点，对吗?

With all of GDB's versatility, there must be a way to do this, right?

推荐答案

您需要启用日志记录:

(gdb) set logging on

现在 GDB 将登录到 ./gdb.txt.你可以告诉它使用哪个文件:

Now GDB will log to ./gdb.txt. You can tell it which file to use:

(gdb) set logging file my_god_object.log

您可以检查当前的日志配置:

And you can examine the current logging configuration:

(gdb) show logging
