True, but Scott Hill replied to Tom Tromey that his suggestions don't work, and that, for some reason, the "silly command" was working in Win98 (but not in NT). See http://sources.redhat.com/ml/insight/2001-q1/msg00050.html.

I, too, tried Tom's suggestions, but had no more luck than Scott.

Just tried it. Doesn't work.

gdb: unrecognized option `--args'
Use `gdb --help' for a complete list of options.

This was Tom's suggestion. Doesn't work.

Doesn't work either.

I missed that message; it's not in the same mail thread as the others. 
Still, the fact that it worked at all is probably a bug. This command just 
does not do what the user thought it would.

Ugh. Cygwin. Right. Ok, you won't have this option available to you, since 
it didn't get in until 5.2, which doesn't work on cygwin (well, the tcl/tk 
that we use don't work on cygwin. Command line gdb works just fine.)

Ok, then the error is occurring below the layer that Insight (and probably 
gdb) work at. I would recommend you start by asking on the gdb mailing 
list about this (gdb@sources.redhat.com). I'm pretty sure they'll just 
tell you to try the cygwin mailing list, but the cygwin maintainer is also 
the cygwin gdb maintainer, so he reads the list. Make sure you've done due 
dilligence before posting (and say that you have): it'll make your life 
much easier. ('due dilligence' = search gdb/cygwin mailing lists for this 
topic)

I wish I had some better news for you, but I don't. Sorry.

Tom Tromey responded to this message... You're problem may be different, 
but the original poster was attempting to do something silly:

$ gdb ./mulitvar < multivar.inf

This tells gdb that it's stdin is redirected from the file! Not what the 
user wanted, I think...

Instead, he has several options:

1) Run "gdb ./multivar", go to File->Target Settings..., choose "Exec", 
and enter "< multivar.inf" as arguments

2) Run "gdb ./multivar --args '< multiar.inf' (syntax may be incorrect -- 
double check it)

3) Run "gdb ./mulitvar", open Console Window, type "r < multivar.inf"

If this doesn't happen on your system, please try doing this with vanilla 
gdb, i.e., "gdb -nw". This doesn't sound like the sort of thing that 
Insight would malign.

input redirection

[antoine.trux]

Hi,

Someone once had problems with input redirection with the Insight Debugger in Windows NT: http://sources.redhat.com/ml/insight/2001-q1/msg00047.html. Several people answered, but the problem remained unsolved (see http://sources.redhat.com/ml/insight/2001-q1/msg00048.html, http://sources.redhat.com/ml/insight/2001-q1/msg00049.html and http://sources.redhat.com/ml/insight/2001-q1/msg00050.html).

I have the same problem. Has any solution been found?

Best regards,
Antoine
