Debugging threaded console-based program

Debugging threaded console-based program

[Bill Bland]

Hello,
	I'm trying to use gdb to find out more about a program whose
source I don't have (and I have no way of getting).  The program is
multi-threaded which causes problems for me if I run it in one terminal
and use gdb in another terminal to attach to it.  This means that I want
to start the program from inside gdb.
Unfortunately since the program is console-based it is very difficult to
see what's going on with the program's and gdb's output going to the same
terminal.  Could anyone suggest a way around this?

Thanks in advance,
		Bill.

You didn't say which platform you're trying it on.  If it's GNU/Linux,
there have been a number of recent fixes in the development sources
with regard to being able to attach to a multi-threaded program.  If
you haven't done so already, you might want to fetch and build a copy
of the developement sources.  Otherwise, you should provide us with more
information so that we can try to fix the problem in GDB.
