我在 linux 上使用 gdb 7.5.1 版,并试图使用方便的功能,比如$_memeq发现它显然不存在:
Undefined command: "$_memeq". Try "help".
当我输入时,help function我得到这个输出:
(gdb) help function
Placeholder command for showing help on convenience functions.
List of function subcommands:
Type "help function" followed by function subcommand name for full documentation.
Type "apropos word" to search for commands related to "word".
Command name abbreviations are allowed if unambiguous.
甚至apropos memeq什么都不返回。为什么会这样?
