gdb mi未定义命令：-显示插入

当我使用

-display insert

显示插入命令

概要

-显示插入表达式

每次程序停止时显示表达式

GDB命令

相应的GDB命令是“display”

我的行动：

我希望

-display insert

可以像gdb中的

display

一样工作，这就是手册所声称的。

这是旧的gdb手册，当前的手册可以在这里找到：

-display insert命令是在2006年从手册中删除的-我不相信这个命令曾经真正实现过。。。。或者，它在2006年之前就已经从GDB中删除了

使用MI时，您需要研究使用GDB/MI变量对象而不是显示命令，请参阅手册的这一部分：

^error,msg="Undefined MI command: display-insert",code="undefined-command"
