将核心文件保存在gdb中

是否有可能使用gdb 保存/转储核心文件? 有时我想保存文件以后再分析。

在gdb中发出'generate-core-file'命令。

(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 Breakpoint 1 at 0x400e0b: file utils/udec.c, line 36. (gdb) r Starting program: /home/nos/build/utils/udec Breakpoint 1, main (argc=1, argv=0x7fffffffe9a8) at utils/udec.c:36 36 int fileargc = 1; (gdb) generate-core-file Saved corefile core.7336 

您也可以使用gcore <pid>来生成核心。
