Isn't sufficient to use  "gdb ... 2>&1 | tee log.txt" ?

(I don't have a unix machine handy and so can't test it).

I just tried this and it works great!  My colleagues and I thank you so
much!

I would still be interested in whether there is a function in gdb to open or
close a log file during a session?

thanks,

It is certainly listed in the TODO file:

--

Add a transcript mechanism to GDB.

Such a mechanism might log all gdb input and output to a file in a
form that would allow it to be replayed.  It could involve ``gdb
--transcript=FILE'' or it could involve ``(gdb) transcript file''.

Re: Unable to step through ARM code using insgiht-5.0

[Ahmed A. Agbabiaka]

Hello,

Thank you all, for your suggestions regarding my GDB problem. I now have a
working version of GDB, "insight+dejagnu-20010205", which I have been using for
over one month now. However, I still have a few more queries:

My build of the snapshot (even though built using cygwin-1.1.18-2, on a WIN 95
platform) only works on Window NT. Attempts to use it on any WIN 95 machines
have failed miserably:
	- Downloading seems to hang half-way
	- When a download is successful, "step"ing crashes the debugger.

Are there any reasons why GDB should not work on a WIN 95 platform? Is this a
known problem, or just a one-off? I am yet to try it on a WIN 98 platform to see
if the same problems occur.

Thanks once again,
Ahmed

capture gdb output

[Michael S. Miles]

I need to be able to capture all the output from my gdb session into some
type of log file.  It seems like this is a feature that would definitely
exist, but I have been searching the sources and documentation for any
mention of this capability with no luck.

Does anyone know if gdb has this functionality and if so, how to use it?

If it helps, I am using the 03/20/01 snapshot of GDB on a Linux-i386 system.
I am also using it as a remote Linux kernel debugger although I don't
believe that is relevant.

many thanks,
Michael Miles

Besides using tee, you could run gdb within an emacs shell session (or use
emacs' gdb mode) and copy the buffer to a file, or use the 'script' command
that many Unixen provide (output is in the 'typescript' file).  On older
systems, xterm might have a logging option (which was disabled due to security
concerns).
