Re: [cdt-dev] Verbose console mode in DSF/GDB

[Marc Khouzam <marc.khouzam@xxxxxxxxxxxx>]

I knew I had seen a DOS window come up!  It was not my imagination :-)
(see https://bugs.eclipse.org/bugs/show_bug.cgi?id=231883)

We should get this feature for DSF-GDB since it is important on Windows.
From what you are saying, we should use the new-console when no PTY is
available (which includes Windows), or should we really only use it on
Windows?  I'm thinking the former.

I'll update the bug with your info.

Thanks!

Marc

Have you ever debugged with CDI/MI and seen an DOS window pop up when
you launch for debug? In recent years our gdb integration does an
explicit "set new-console off" explicitly to turn off this feature as
we try to capture the stdout from the inferior. Unfortunately that I/O
is buffered on Windows (we use pty to force the output on Linux), and
worse, on exit it doesn't flush, it's just gone. If you let a console
pop up naturally you'll see the output there as the program steps.

Now, for some reason, the checkbox in the MI launcher that is supposed
to enable/disable is greyed out and the feature is disabled (even
though the checkbox is turned on). We had a customer run into that and
we had to tell them to use the "Standard" instead of "Standard
(Windows)" command factory to bypass the "set new-console off" call.
It's ugly all 'round.
