I'm trying to use gdb to debug an EPICS soft-ioc on linux (RHEL-5). Does anyone know how to redirect the iocsh stdin and stdout to another terminal?
The gdb manual says to use "set inferior-tty /dev/pts/0", but when I
try it I get the following warning on /dev/pts/0:
warning: GDB: Failed to set controlling terminal: Operation not permitted
What version of gdb are you using? I encountered this in the past and discovered it was a bug in GDB
[ernesto@jaguar proj]$ rpm -qa |grep gdb gdb-7.0.1-23.el5_5.2
I then see normal iocsh output up to the iocInit() call, but then I get an error on the gdb tty that says "Spurious thread death event" and typing commands on /dev/pts/0 results in that command being sent to bash instead of the gdb iocsh.
Any suggestions would be welcome. Thanks, - Bruce Hill
