RE: non-DSO mod_perl, Embperl, and AIX not working
After making a few tweaks to the test.pl script and passing the 'h' command-line parameter (only do mod_perl tests) I was able to run all the tests (only under mod_perl) successfully. I then was able to run some successful tests against some .epl's that I had previously written using a different OS. I can't run Embperl outside of apache, but have only done that on the rare occasion anyway, so that's not a great loss. Thanks for all your help.

Aiee, I have forgotten about that one, but with Apache 1.3.10 they added
a special AIX 4.2 feature to the httpd.exp file that explicitely forces
the httpd symbols to be from the main part and to be present, previously
the httpd.exp file specified deferred binding that also allows for the
symbols to be not present, which might not be a problem if you know that
and don't use functionality that requires the use of the unresolved
symbols. I changed that back to the old behaviour in my Apache build
tree by changing the first line of the httpd.exp from:
#! .
to just:
#!
without the dot. This way Embperl should also run standalone with perl
alone.
Thanks for all your help. It has been a few years since I have used AIX and
was in much need of reminders related to AIX's "strange/different/odd/weird"
linker.
Yep, compared to other Unix linkers AIX behaves quite differently, but
the export file mechanism is actually quite nice if you really want to
control the API exported from shared libraries or plug-in modules. Other
Unix linkers can be coerced to perform similarly, although with some
additional effort. I do use these features, as I do not like it if
everything is dumped into one big symbol soup, as the ELF linkers
normally do.
BTW, is it appropriate for me to offer to help with incorporating your
knowledge into the Embperl install scripts?
Definitely, but I believe Embperl already knows about it. There is the
following sequence in Makefile.PL from Embperl:
require Apache::src;
$dynlib-{'OTHERLDFLAGS'} = Apache::src-new-otherldflags
if (defined (Apache::src::otherldflags)) ;
This would pick up the requires flags from modperl, if modperl knows
about them. As currently done the httpd.exp is only added to
otherldflags if modperl is build by apxs as a DSO, not if linked into
httpd statically. I would believe the following patch to modperl should
fix this:

RE: non-DSO mod_perl, Embperl, and AIX not working
Those are internal functions to apache, like helper functions.

BTW: I think you're looking for libap.a, I just poked through that archive of object files, and it contained the symbols you're looking for. I don't know if AIX supports linking in archive files, but if not just link in by hand all the object files in that directory.

RE: non-DSO mod_perl, Embperl, and AIX not working
Before I sent my original message, I tracked down all the symbols, and their object/library files. I added several ".o"'s and ".a"'s from the apache and mod_perl source trees, a couple from "/usr/lib/perl" and a couple from /usr/lib via '-lxxx'. After I got a clean link (there were some "duplicate symbol" errors) I had the same problem (seg. faults) as I had with the '-berok' flag. -Original Message- From: Shane Nay [mailto:[EMAIL PROTECTED]] Sent: Tuesday, June 13, 2000 8:22 PM To: Greg Estep Cc: [EMAIL PROTECTED] Subject: RE: non-DSO mod_perl, Embperl, and AIX not working Those are internal functions to apache, like helper functions.

It is not buggy, it is just very different. Most unix linkers consider global variables from all shared objects that comprise a process image as one global space. The AIX linker does not do that, it does explicitely require you to specify which global symbols enter the inter-module name space through the use of .exp files. If you link in global symbols from some .o files these are not global symbols for other shared objects unless being made inter-module global by an .exp file. -- Jens-Uwe Mager HELIOS Software GmbH Steinriede 3 30827 Garbsen Germany Phone: +49 5131 709320 FAX:+49 5131 709325 Internet: [EMAIL PROTECTED]

I also tried '-G' with similar results. Without the modification to LDDLFLAGS I got several "unresolved symbol" errors. I also get similar results with Embperl 1.2b9, Apache 1.3.9, and mod_perl 1.23. BTW, I did not personally compile my perl executable, it is straight from a fileset on the AIX 4.3.3 CD. I have, however, upgraded several modules to their most recent CPAN version. My 'perl -V' output looks like this: Summary of my perl5 (5.0 patchlevel 5 subversion 3) configuration: Platform: osname=aix, osvers=4.3.3.0, archname=aix uname='aix funny 3 4 01716600 ' hint=recommended, useposix=true, d_sigaction=define usethreads=undef useperlio=undef d_sfio=undef Compiler: cc='cc', optimize='-O', gccversion= cppflags='-D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE - qmaxmem=16384' ccflags ='-D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE - qmaxmem=16384' stdchar='unsigned char', d_stdstdio=define, usevfork=false intsize=4, longsize=4, ptrsize=4, doublesize=8 d_longlong=define, longlongsize=8, d_longdbl=define, longdblsize=8 alignbytes=8, usemymalloc=n, prototype=define Linker and Libraries: ld='ld', ldflags ='-s' libpth=/lib /usr/lib /usr/ccs/lib libs=-lnsl -ldbm -ldl -lld -lm -lc -lcrypt -lbsd -lPW -lC_r libc=/lib/libc.a, so=a, useshrplib=false, libperl=libperl.a Dynamic Linking: dlsrc=dl_aix.xs, dlext=so, d_dlsymun=undef, ccdlflags='- bE:perl.exp' cccdlflags=' ', lddlflags='-bhalt:4 -bM:SRE - bI:$(PERL_INC)/perl.exp -bE:$(B ASEEXT).exp -b noentry -lc' Characteristics of this binary (from libperl): Built under aix Compiled at Aug 14 1999 08:59:55 @INC: /usr/opt/perl5/lib/5.00503/aix /usr/opt/perl5/lib/5.00503 /usr/opt/perl5/lib/site_perl/5.005/aix /usr/opt/perl5/lib/site_perl/5.005 . -- Greg Estep [EMAIL PROTECTED]
