linux - gdb 管道重定向错误 : (gdb) Hangup detected on fd 0

Question

求助，我该如何解决？我无法将命令从 stdin 重定向到 gdb。

我收到这个错误:

charmae@charmae-pc:~/workspace/AVT$ echo "list" | gdb a.out

Answer 1

另一种很好用的技术是使用 here-document 将输入重定向到 gdb:

gdb -quiet -nx << EndOfInput
thread apply all bt
quit
EndOfInput

这使得无需使用临时文件即可编写控制 gdb 的脚本成为可能。它似乎完全避免了“检测到挂断”消息。
