emacs-19.34 segfauls when built with Xfree 4.3.0 (glibc 2.3.x, gcc 3.2)

[Hin-Tak Leung]

I am trying to build emacs-19.34 against glibc-2.3 and Xfree 4.3.0
on linux with gcc 3.2. The binary works with -nw switch, but
when I run it without -nw, it segfaults with Fatal Error(11).
So it seems to be an X-related problem.

I had an older binary which was compiled by gcc 2.95.x against
Xfree 4.1(?) and glibc-2.1 (maybe 2.0?) which still works on
this current system.

have you tried using a more recent version of emacs? emacs-21.3.1 is
what i use and it compiled with gcc-3.2.3 on XFree86-4.3 no problems
(glibc-3.2.3) using using Lesstif-0.93.41. unless there is some reason
you WANT to use an older version?

cheers,

Re: emacs-19.34 segfauls when built with Xfree 4.3.0 (glibc 2.3.x,gcc 3.2)

That's a somewhat time-wasting question - if I am on linux with
gcc 3.2 glibc 2.3.x and Xfree 4.3.0 most certainly the linux
distribution I use come with a more recent version of emacs or xemacs.
(actually both). And my original post mentioned that I built emacs-19
successfully on a Xfree 4.1/glibc 2.0/2.1 system as well,
and that binary still works on the current system.

I want to use a elisp script called cemacs (for Chinese inputs)
but unfortunately the inclusion the MULE (Multi-lingual Extension)
since version 20 has broken it. It does continue to work with
xemacs-21.x, but that's besides the point.

Now back to my question: why emacs 19.34 segfault when built against
glibc-2.3 and Xfree 4.3.0? And please stick to the question... -
and please do not ask why I don't switch to xemacs, or use MULE.

Just to anticipate these two questions: MULE is no where as good
as cemacs (unfortunately, and please don't start an argument on why I
should use MULE even though it is inferior), and xemacs is too
bloated for my taste. So I would really rather try to keep using
a small installation of 19.34 (in addition to emacs 21 which came
with the distro), or port cemacs forward to emacs 21 (quite major
work, probably). The 2nd option is probably better for long
term, but until it is done, I will continue to try to build emacs
19 on current systems... and I would really like to find out
why it won't build.

in this case probably no one can answer your question w/o your investing
effort into debugging the matter locally.  as well, probably few people
are interested in helping you if you scold them.

of course, there is the option of hiring someone to work on this problem
for you, in which case you can treat them as befits the conventional (in
your business sphere) employer / employee relationship, and clearly set
out in a written contract.  you may consult the etc/SERVICES file to
find someone in your vicinity, or further away on the net.

That's another pointless reply... you still have not offered
any substantial help - e.g. suggestion for compiler switches,
small modification at the source level, etc.

FWIW, I had tried both "-D_BSD_SOURCE" (the default)
and also "-D_GNU_SOURCE -D_BSD_SOURCE" (how the redhat
4.x rpm was built). Both binaries work happily with "-nw" inside
an xterm and seg-fault under X.

Thanks for another "I am trying to help and I am not saying anything" post...

(Sigh) A 3rd "See I am so helpful" post. Look - there is no
useful content in any of your three replies.

Other than my stated reason (an important old elisp script that
doesn't run under current versions), I think the memory foot-print
and launch-time could well be the reason for anybody wanting
to run emacs-19 or even earlier on current systems instead of the
current. As you say, it is a frequent-enough request, and I asked
a legitimate question that you fail to address anywhere close
in 3 posts...

Why can't you just try to answer a straight-forward question,
as you seem to suggest you "want to help"? As it turned out,
if I had mentioned cemacs (and mentioned that I don't want
to use MULE), I would be drawing myself into a
flame war regarding MULE's merits. That had seemed to be a
sensitive subject to some others (ttn@glug.org - who I believe
is possibly involved in MULE's development as I seems to have
come across that name in other projects). It is a fairly personal
choice - cemacs versus MULE, emacs 19 versus 21, and I don't really
need to explain why I prefer one to the other.

I asked a technical question and reported a possible bug
of an old unmaintained version of emacs, which I believe
some other people may like to continue to use for their own
reasons - those reasons are somewhat irrelevant to the question.
I would really prefer it to stay that way.

they were not replies to the list... they were personal replies to you!
and were not intented for the list, so please remove me from your
CC's!!!

i offered help, you were a wanker about it... end of story. it had
NOTHING to do with the emacs mailing lists at that stage. now please
stop spamming me!

i apologise to all others on the list for this off topic email,

Bugs (and a crash is a sign of a bug) should be reported to
gnu.emacs.bug, not to gnu.emacs.help.

I find it hard to believe you will find someone who will debug this
for you in such an old version of Emacs.

I looked thru etc/PROBLEMS and found there an entry about crashes at
startup when Emacs is built with XFree R6.4; there's a patch there for
Xlib, which perhaps will help you (assuming that PROBLEMS describes
the same problem there).

Yes, it is a GNU/Linux system.

As it turns out, the solution (adding '-z nocombreloc' to LDFLAGS)
fixes problem with building current version of emacs as well.

It is a problem with 'combreloc' becoming the default since March 2002 in
GNU ld so it affects very new GNU/Linux system when trying to build
all versions of emacs and xemacs, in addition to very new GNU/Hurd systems,
and any other system for which GNU ld is the default linker and for which the
version of GNU ld is less than 14 months old.

I'll address cemacs/MULE separately.
