我正在尝试调试处理请求时分叉的进程。
我已将follow-fork-mode设置为child允许gdb在命中子节点时遇到中断。但是，当我从孩子那里继续时，父母会分离。
很多文档指向选项detach-on-fork，但如果我尝试设置此选项，我会得到：
(gdb) set detach-on-fork on
No symbol "detach" in current context.
该选项明确地与：http://sourceware.org/gdb/onlinedocs/gdb/Forks.html

(gdb) show detach-on-fork
Whether gdb will detach the child of a fork is on.
我猜它是在6.3到6.5之间添加的。我没有意识到这个盒子有这么老版本的gdb。谢谢！
如果评论的任何人想要添加答案，我会接受它！
