That seems to have fixed it. As I suspected - user (me) error.

a) working with shared_library stored in the archives 
(${prefix}/lib/libapr.a and ${prefix}/lib/libaprutil.a


Will test again another day with static apr libraries (only). Advantage 
of static could it removes two install dependancies, and maybe slightly 
faster.

Are you sure that the libapr you're scrutinizing is being loaded at runtime?

Thanks for the feedback!

Question re: build of (64-bit) httpd and issue with apr_password_validate

[Michael Felt]

a) I expect I have "enabled" a new httpd flag as I attempt to build a 
comprehensive 64-bit version of httpd for AIX - so I expect this is a 
"user error". I am hoping for feedback on where to look (short path is 
to not load mod_authn_file, for now). I shall try same build as 32-bit 
and see if the issue goes away.


b) I have built apr and apr-util "differently" than in the past in that:

b1) added --with-crypto

b2) added --with-ldap-dir=/xxx and --with-ldap=ldap

Current ./configure command

It was created by configure, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ../src/httpd-2.4.23/configure --prefix=/opt 
--sysconfdir=/var/httpd/etc --sharedstatedir=/var/httpd/com 
--localstatedir=/var/httpd --mandir=/usr/share/man 
--infodir=/opt/share/info/httpd


c) After build completes - apachectl -t fails with:

root@x064:[/data/prj/apache/httpd-2.4.23]apachectl -t
httpd: Syntax error on line 66 of /var/httpd/etc/httpd.conf: Cannot load 
modules/mod_authn_file.so into server: rtld: 0712-001 Symbol 
apr_password_validate was referenced

from module /opt/modules/mod_authn_file.so(), but a runtime definition
of the symbol was not found.\nrtld: 0712-002 fatal error: exiting.

root@x064:[/data/prj/apache/httpd-2.4.23]nm 
/opt/modules/mod_authn_file.so | grep apr_password_validate

.apr_password_validate T  4294970628
.apr_password_validate t  4294970628  40
apr_password_validate U   -
apr_password_validate d  4563406976   8

root@x064:[/data/prj/apache/httpd-2.4.23]nm /opt/lib/libapr*.a | grep 
apr_password_validate

.apr_password_validate T   0
apr_password_validate D 928  24
apr_password_validate d 896   8
.apr_password_validate T  4295008768
.apr_password_validate T  4295027960
.apr_password_validate t  4295027960  40
apr_password_validate D  4563413360  24
apr_password_validate d  4563420512   8

So, it seems, for some reason - during "make" I think, the U line ( 
apr_password_validate U   - )
has not resolved to the line "apr_password_validate D 
4563413360  24"

while the "T, t, and d" lines did.

And, just to be sure this is not an issue of 32 versus 64-bit listings:

root@x064:[/data/prj/apache/httpd-2.4.23]nm -X32 /opt/lib/libapr*.a | 
grep apr_password_validate

.apr_password_validate T   268475264
.apr_password_validate T   268492664
.apr_password_validate t   268492664  40
apr_password_validate D   536881340  12
apr_password_validate d   536884916   4
.apr_password_validate T   0
apr_password_validate D 912  12
apr_password_validate d 896   4

and

root@x064:[/data/prj/apache/httpd-2.4.23]nm -X64 /opt/lib/libapr*.a | 
grep apr_password_validate

.apr_password_validate T   0
apr_password_validate D 928  24
apr_password_validate d 896   8
.apr_password_validate T  4295008768
.apr_password_validate T  4295027960
.apr_password_validate t  4295027960  40
apr_password_validate D  4563413360  24
apr_password_validate d  4563420512   8

Many thanks for your ideas!
