[Message part 1 (text/plain, inline)]

> Please describe exactly what actions triggered the bug
> and the precise symptoms of the bug:


- Installing emacs 23
- Loading perl-code with errors
- M-x mode-compile

- Effect: The errorlines, filenames and linenumbers are not recognized or
activated in *compilation*

No problem whatsoever with emacs 22 and the same configs!

The problem didn't occure while compiling sh or python files!!!

The problem was reproducible on different machines with Ubuntu 8.04 and 8.10
but not with Windows XP, all with default installation with German
localization.

It was reported NOT to happen with Ubuntu 9.04 on an american machine.

For detailed discussion including a WORKING REGEX-PATCH for mode-compile.el
please look at:

-->
http://groups.google.de/group/gnu.emacs.help/browse_thread/thread/c1a62e304177fefe/9a28488347dd77e7#9a28488347dd77e7

-->
http://groups.google.com/group/emacs-perl-intersection/browse_thread/thread/328823127d1f8b7/8adaceafa79cc216#8adaceafa79cc216

DIAGNOSIS: It seems like the handling of regexes in compile.el changed
considerably from
22 to 23, breaking compatibility with mode-compile.el!!!

A sample perl code to produce 4 error-lines is:
-------------------
use strict;
$a=A;
print $a;
$a=A;
$a=A;
$a=A;
--------------------

> If Emacs crashed ....

No crash!

Then mode-compile probably needs updating.

Glenn, as I showed, the behavior  of emacs 23 in this respect is very
inconsistent on different systems.

If mode-compile and cperl-mode need an update it would be only fair to know
to which specification it needs to be updated to!

Or do you think emacs 23 is not an example of consistent software???

OK, but I just replied to all recipients of your mail...

Sorry, I've spend much time to isolate that bug and I don't wanna be part of
any kind of  xemacs vs emacs flame war in response.

compile.el of emacs 23 acts inconsistently and I think if it's due to
different system or unicode settings it's only  one incarnation of a bigger
underlying bug, one could be worried of ...

Yes, I first replied to your original report without noticing that you
had cc'd the authors of compile.el.

Nobody has mentioned XEmacs. I was asking you not to bother the
blameless original authors of compile.el, one of whom has not touched
the code in over 12 years.

Glenn,

Neither mode-compile nor cperl-mode are necessary to reproduce the problem.

And after 12 years a maintainer might perhaps consider to delete his email
address.

Anyway I met Daniel Pfeiffer on the last German Perl Workshop,  I'm going to
provide him directly with more detailed infos in German.

No need to bother you longer...

Thanx for your help!
  Bye

OK. If you want someone on this list to help fix anything, then the
way to go about it is to provide a complete, self-contained recipe
starting from `emacs -Q'. This does not seem to exist anywhere in
either of the two linked threads which I took the trouble to read.

We leave the original Author: header intact to respect people's
contribution. Note that the Maintainer: header says "FSF".

None of this is at all revelant though, because the documented
procedure for reporting an Emacs bug is to use M-x report-emacs-bug.
That is all. Do not cc every email address you might find in the
source files.

Then please file a bug report about that inconsistency, rather than 
reporting a bug in mode-compile, which is not part of Emacs.

hi guys

I'm the original developer of mode-compile but unfortunately I do not use it 
almost for years now, and I even forgot almost anything about elisp :) (my only 
use of emacs is to edit html & css files now).

If somebody have the courage to maintain it, it will be with great pleasure.

best

[Message part 1 (text/plain, inline)]

Hi Heddy

I doubt that mode-compile is to blame, neither of the following combination
succeeds in capturing and activating the error-lines, like it does with
emacs 22:

:~$ emacs-23.1.50 -Q -debug-init -no-site-file  ~/tst.pl -f cperl-mode
--eval='(compile "perl ~/tst.pl")'
:~$ emacs-23.1.50 -Q -debug-init -no-site-file  ~/tst.pl -f perl-mode
--eval='(compile "perl ~/tst.pl")'

Si tu cherche quelqun pour continuer mode-compile: A mon avis il sera mieux
de demander a gnu.emac.help. Ici en insiste seulment que c'est pas un part
integral de emacs.

De toute facon merci bien pour mode-compile!!! :-)

Bye
  Rolf

Thanks. If only we could have started here.

I guess this is a duplicate of bug#3928. (The patch in that report has
some issues, eg XXX in the perl part.)

And for a good reason.

If you really think it is a bug in Emacs, please send precise,
complete instructions, starting from "emacs -Q" and including anything
needed to reproduce it.

Oh, and it seems when you said "emacs 23", you meant "CVS trunk".

Yes ... 23.1.50 is indeed not considered stable...

To be sure, I just installed GNU Emacs 23.1.1, which doesn't show any of
these problems.

Sorry, Googling for "emacs 23 install" predominantly leads to advices for
"CVS trunk" installations, even including complete ubuntu packages, which I
have trouble to find for the stable release...
