No problem, but the approved method is to send your query to cygwin a 
cygwin d com, with "screen" in the subject.  I should normally see that, 
and then other cygwin readers will also benefit from the discussion.

OK.  I later changed the version number from 1 to 0test1, so the URLs for 
download are now

Yes, the reattachment problem is now solved AFAICT, using Cygwin 1.5.17 or 
later.  Most of it works just fine, but there's one problem that I haven't 
solved yet:  when you detach a session, it stays bound to its parent 
shell.  So if you then try to exit the parent shell, it hangs.  You can 
terminate the parent shell, but then screen exits too.  Obviously this 
takes away one of the big advantages of screen, which is the ability to 
detach a session, leaving it running in the background, and then reattach 
later from a different terminal.

I've gotten some hints about how to attack this problem, but I just 
haven't been able to spend any time on it yet.  It's high on my to-do 
list.  Screen is great, and if I can solve that one problem it will be 
ready for Cygwin.

There are also a few terminal oddities and intermittent display problems. 
But these are minor, so I don't think I'll wait for them to release the 
package.  At least, I can put it into testing so people can try it out 
while I work on resolving the other problems.

> Will this have any impact on having a version of screen that works?

I have a working version of screen on Cygwin.  I use it daily, and it works
fine.  With CYGWIN=tty set, the reattachment bug appears to be solved; it
detaches and reattaches sessions normally, which was a problem for a long
time.  Not many patches are needed any more.  More patches used to be
required, one of which was specific to Win9x, but I believe that
improvements in the Cygwin DLL have rendered those unnecessary now.

At this point I know of only one main outstanding bug in screen:  when you
kill a window or the whole screen session, the child processes aren't
killed.  They hang around and you have to kill them manually.

screen is an extremely useful program, that people have been asking for in
Cygwin for a long time.  I'd be willing to package it, but when I floated
the idea a year ago or so, the feeling seemed to be that there were still
too many bugs to make it useful.  If people can live with (or even better,
test and help me try to fix) the unkilled-child-process bug, then I'm
willing.  I could release it as a test version.

Yes?  No?

What do I have to do with this?  If you are responding to something that
I said then please post a reference and don't leave everyone guessing.

Otherwise propose to package it using the standard procedure.

I was imagining that you would remember the conversation.

...from almost two years ago.  Uh huh.

>http://www.cygwin.com/ml/cygwin-apps/2005-04/msg00183.html

So, as I so wisely said two years ago: If you can't use one of the major
features of screen, it doesn't sound like the package is ready for prime
time.

And, just in case you're wondering if I am going to volunteer to help you
track down problems - I'm not.  So, maybe anyone who wants screen should
volunteer to help.

No, that was not my intention.  I was trying to be courteous.  But that's a
two-way street.  Forget it, I won't bother next time.

Since you were pinging me and since (on rereading) you were consistently
asking for help, I don't think it was a huge leap for me to surmise that
you might be wanting my help debugging problems.  By stating my
intentions, I wanted to make it clear that someone else needs to step
in.

You know this kind of things just shuts people off and turns them away right?
People are trying to make progress, trying to make things better, and they're
basically being told to go away. If he could do it himself, I'm sure he would
have solved the issue by now. If he can't, perhaps he needs the help. I don't
see what's so groundbreaking about "I'm not going to be able to help you with
it now as I'm too busy, but perhaps throw the idea out there along with your
observations and see who else bites." Is that somehow worse than "Look, I don't
have the time to help you track down problems, find someone else." ?

hmm I have not had that problem? I run rxvt's with bash and can exit all
terminals leaving no bash process but screen lives on. I can then fire
up another shell and re-connect to screen and any jobs it has running.
(ie it works just like it should!)

Interesting.  Okay, I hadn't noticed this before, but the problem does
seem to be particular to the Cygwin console.  It doesn't occur with
rxvt.  Also, it doesn't occur in the Cygwin console if I start a
subshell first, and invoke screen from there.  Maybe useful to know.
Still, I do want to solve the problem before I release screen.

I'd love to have your problem.  Where'd  you find 'screen'?

Try 'screen -ls' to list currently active screen sessions.  It's 
possible that the cygwin port is borked.

Peace.

There is no Cygwin port (or an official package) of screen.  I posted a
patch a while ago that would make it compile (and sort of run).  It's
possible that screen relies on some features that aren't portable.

screen

[Cant]

just for fun i thought i would try and install screen... but for some reason
when i go to make it, it says this:

$ make
CPP="gcc -E " srcdir=. sh ./osdef.sh
AWK=gawk CC="gcc -g -O2" srcdir=. sh ./comm.sh
AWK=gawk srcdir=. sh ./term.sh
gcc -c -I. -I.    -g -O2 screen.c
gcc -c -I. -I.    -g -O2 ansi.c
gcc -c -I. -I.    -g -O2 fileio.c
gcc -c -I. -I.    -g -O2 mark.c
gcc -c -I. -I.    -g -O2 misc.c
misc.c: In function `xsetenv':
misc.c:648: too few arguments to function `setenv'
make: *** [misc.o] Error 1
$

Re: screen

[Igor Pechtchanski]

Try "patch -p0 < patchfile" from the screen source directory.  Be
prepared, thought, that it might reject some chunks...  You'll have to
adapt the chunks rejected yourself.

As for the otter, see the following thread:

 SUBLIMINALLY ENTICE ANY WOMAN TO BE YOURS!
              GUARANTEED.

We know you may be skeptical, but if you're not totally 
satisfied with your sex life and who you're dating you owe 
it to yourself to visit our web site (your choice of 
ENGLISH or ESPANOL) at http://208.166.10.22/ and learn 
how the power of subliminal mind control can change your 
life. It is simply a fact that sexual impulses can be 
awakened and greatly intensified by using subliminal 
commands. We guarantee it!

But, most subliminal enticement tapes don't work. Confused? 
Take 1 minute, go to  http://208.166.10.22/ and read the 
section entitled "THE NUMBER 1 REASON OUR TAPES WORK 
AND THEIRS DON'T!" to find out why.  If nothing else, 
you'll get a good laugh at how downright silly some other 
tapes are.

  EVERYTHING (AND WE MEAN EVERYTHING!) TO GAIN 
              AND NOTHING TO LOSE!

We're so sure that OUR tapes work that every one comes with 
a 100% MONEY BACK GUARANTEE!

Now that you know about the hottest tapes on the Internet, you 
have no excuse not to be successful with any woman you choose. 
If you don't get the facts, you are cheating yourself out of 
HAPPINESS, ROMANCE, GREAT SEX and the TIME OF YOUR LIFE!
