在gdb中保存核心文件 [英] Saving core file in gdb

问题描述

是否可以使用gdb来保存/转储核心文件？有时我想保存文件以便稍后进行分析。

Is it possible to save/dump core file using gdb? Sometimes I want to save file to analyze it later.

推荐答案

在gdb中发出'generate-core-file'命令

Issue the 'generate-core-file' command in gdb.

(gdb) help generate-core-file
Save a core file with the current state of the debugged process.
Argument is optional filename.  Default filename is 'core.<process_id>'.
(gdb) break main
