tcsetpgrp failed in terminal_inferior: Inappropriate ioctl fo r device

[Pergola, Michael]

Kyle,

I have not resolved this issue but I experience the same thing, i. e.,
gdb runs OK but the messages are annoying. I think this msg has
something to do with the termios as the tcsetpgrp is a system
call under this kernel function.
