Apache crashing on mod_perl installation.
Hi all,
I'm having a frustrating time with mod_perl...
Configuration:
-- apache 1.3.22
-- mod_perl 1.26
Static configuration & installation all goes fine, and when I run httpd
(w/o modification, off of a straight install) the child pids crash when
loading /. (Loading /index.html works fine. Perl files do not.)
The specific error messages is this:
[Mon Dec 10 00:46:01 2001] [notice] child pid 31524 exit signal Segmentation fault (11), possible coredump in /disk/u/t/software/try2/ap-install
When I do a gdb on the resulting core dump, I find that it's crashing in
perl_handler().
Any ideas?
thanks,
--titus

The only time I've had real grief with building was when I did that.
One of the problems is that it's difficult to make sure that all the
permissions are right if you move away from the 'standard' layout, and
if you meddle with that and the makefiles then it's near impossible.
Still, a lot of people do it and manage OK. I really just wanted to
know if you can get things working OK without moving too far off the
beaten path. If you can, then it's generally easier to trace where it
all goes wrogn when you start changing things.

Core dumps and segfaults are common enough, I meant that I hadn't seen
it happen for the reason you gave.

No, no reply. It happens.
Really must hit the sack now...

Bear in mind these are in the instructions for installation for mod_perl ;).
But no, I haven't, because I haven't figured out how to have it (mod_perl)
specify a different path in configuring apache, and I don't want it to
install in the default place.

yep.

People have had problems with mod_perl and child pids core dumping, at least;
http://www.mail-archive.com/modperl@apache.org/msg21703.html
is one of the (~6) messages I found dealing with black-box seg faults...
http://aspn.activestate.com/ASPN/Mail/Message/modperl/784385
is another one, to which you responded, in fact ;). I don't see any
followups from the original person tho.

Can you point me to examples? I don't recall seeing anything quite
like this before.

OK,
apache 1.3.22
mod_perl 1.26
Output of 'perl -V' attached.
I configured Apache with:
% ./configure --prefix=~/software/try2/ap-install
then ran 'perl Makefile.PL' in the mod_perl directory. It found the source
directory correctly, and I told it *not* to autobuild apache.
Inside mod_perl directory,
make
make install
w/o error.
I then returned to the apache directory, issued:
./configure --prefix=~/software/try2/ap-install --activate-module=src/modules/perl/libperl.a
modified src/Makefile to include the correct stuff:
EXTRA_CFLAGS1=`$(SRCDIR)/apaci`
EXTRA_LIBS=`perl -MExtUtils::Embed -e ldopts`
EXTRA_CFLAGS=$(EXTRA_CFLAGS1) `perl -MExtUtils::Embed -e ccopts`
did make & make install.
% bin/httpd -X
crashes on first connection attempt to 'localhost:8080/', although
'localhost:8080/index.html' works fine. The error_log just says
that the child pid exited abruptly.
Error message from w/in GDB:
--
% gdb bin/httpd

I've tried to compile with -g but for whatever reason the symbols don't seem
to be coming through. Ergh.
Help? People have had this error before, to judge from the mailing list
archives, but I haven't seen a useful solution yet.
