Re: AIX, dlopen problem?
Jens-Uwe, Listees:
Sorry that it has taken me about a week to get back to you. It has been
busy, and this problem had backgrounded itself.
Starting off w/ a fresh compliation of apache 1.3.12 mod_perl 1.24, I
ended up with the same errors as before. I then added the flags that you
suggested to link my module. The httpd.exp file it expects for some
reason is /httpd.exp. I copied the httpd.exp from src/support to /. At
this point, the module compiled/linked correctly. I added the PerlModule
line to the httpd.conf to include it, and achieved the same broken
httpd. (See attached or below for details.)
Attached is a (long) listing of both the compilation linking as well as
the 'dump -nv AuthenKerberos.so' that you suggested would be helpful. I
tried to read the dump - however I just don't quite understand it.
A few other notes: The module demands some mod_perl functions -
perl_cmd_perl_FLAG, perl_cmd_perl_TAKE1... (in attached file) which I was
previously told were not usually exported by mod_perl, but I could put the
symbol names in my mod_perl.exp file to help with linking. I added those
symbol names before compiling mod_perl.
(I also had some odd problems at the "perl Makefile.PL" stage - If I
left the arguments in a certain order it would work, another order would
cause segfaults :( - the make test worked fine when run by hand. Since
the problem I am having was the exact same under this new configuration
and the other - I am assuming this is something random and
circumstantial.)
thanks,
jamie

This suspicially looks like you have some imports in the AuthenKerberos
wrong. Modules that are plug-ins to Perl but at the same time need to
reference Apache symbols need some more ld flags to compile. The
Apache::src modules knows which:
$ perl -MApache::src -le 'print Apache::src-new-otherldflags;'
-bI:/usr/local/lib/perl5/site_perl/5.005/aix/auto/Apache/mod_perl.exp
-bI:/usr/local/apache/libexec/httpd.exp
Add these to the link line of the AuthenKerberos module. If that still
does not work, I would need to examine the exact link command line and
the output of "dump -nv AuthenKerberos.so".
