Debugging multiple remote targets

Debugging multiple remote targets

[Aurelio Remonda]

Hello, I intend to debug remote multiple targets with gdb. The idea is
to have two
inferiors and then add a target to each one for simultaneous debug.
Something like:

(gdb) add-inferior
Added inferior 2

(gdb) info inferiors
  Num  Description       Executable
  2    <null>
* 1    <null>

(gdb) target remote localhost:1235
Remote debugging using localhost:1235

(gdb) inferior 2
[Switching to inferior 2 [<null>] (<noexec>)]

(gdb) target remote localhost:1236

But when I try to add the second target i get this:
A program is being debugged already.  Kill it? (y or n)

Apparently gdb does not support this. I found this wiki:
https://sourceware.org/gdb/wiki/MultiTarget

Was this work on MultiTarget gdb intended to support this kind of things?

Thank you!

Yes, I believe so.  That work wasn't completed.  I've been trying to pick it up.  I've made some progress but it is not ready for others to try yet, and some other work distracted things for a while.  I will now get back to it.
