Emacs not redisplaying

Emacs not redisplaying

[Henrik Jegbjerg Hansen]

I have a problem with Jabber and ERC.  At first I thought it was
jabber-specific, but since it also happens with ERC, it must be more
general:

When I sit idly in Emacs (or use firefox, for example), and touch
nothing in Emacs -- messages in ERC and Jabber does not show up, and I
get no notifications of any kind, in the mode line or echo area, or
anything.  Only when I touch a key (e.g. C-f) in Emacs do they come, all
at once.  

How can this be?  And how can I fix this problem?

Thanks,
Henrik Jegbjerg Hansen

I'd like to hook myself in here, too, as I'm experiencing the same 
symptoms with compilation-mode on Emacs 22.0.93.1 (Linux, GTK). 
There might be a relation to Henrik's problem.
Note that I have `compilation-scroll-output' set to t.

Output actually seems to keep appearing for a few moments after 
the key stroke.

Have fun

Just to add: I use the same Emacs version, 22.0.93.1.

And this is the same for me too.

For me, the culprit is cedet.

When investigating the thing a little more (in order to come up 
with a minimal reproduction set), I found that compilation output 
appears fluently until I load "cedet-1.0pre3/common/cedet.el".

Henrik, do you use cedet, too?

I found a message in the emacs-pretest-bug archives
(http://lists.gnu.org/archive/html/emacs-pretest-bug/2006-10/msg00013.html) 
that suggests installing cedet from CVS.  So I'll do just that.

If it does work afterward, do you think one should still file a 
bug report, as the solution would require a non-released cedet 
version?

The compilation output is fine with cedet from CVS as of today.

Same happens for me - and I have cedet loaded too. It jams output from
ecr and other eshell scripts I use.

What modules? Or all of cedet? When I try to make it it says the makefile
is out of date. Any pointers appreciated.

Yes.  Well, actually I don't, but I load all the libraries, which
amounts to the same thing as far as this problem is concerned.

Since I don't use CEDET for anything, I just uninstalled it.  And I can
confirm that everything works for me now, with no problems: I get output
from jabber immediately, even when idle.

That sounds like a good idea.  And thanks for the help, Daniel!

Well, I used cedet-1.0pre3 before, so I pulled all of cedet from 
CVS, into a clean directory.  There, make worked like a charm for 
me (using Emacs 22.0.93).  What did you try, Hadron?

 From what I gathered from around the net it seems that the 
semantic module is what's causing all the trouble.

The same, and I get this:

Makefile is out of date! It needs to be regenerated by EDE.

Try

find -name Makefile -exec touch "{}" \;

from cedet directory. Cedet should compile then fine.

Just to get this right:  Is this about building cedet itself or 
building another project with EDE-controlled Makefile?

Building cedet itself. The touch did it (+I had to install texinfo).

Thanks guys : problem of screen buffering is now solved.
