How did you configure APR and httpd? What version of APR? Is the same version of APR found at runtime [via bin/envvars or other shared lib environment variable?]
APR version pware53.apr-util.rte 1.3.9.0 COMMITTED Apache Portable Runtime pware53.apr.rte 1.3.12.0 COMMITTED Apache Portable Runtime 1.3.12 I have downloaded the httpd-2.2.15 and then followed the process $ ./configure $ make $ make install $ PREFIX/bin/apachectl start
None of those symbols are a part of apr 1.3.x AFAICT, so you probably built against the bundled APR or some other one that had headers installed. Loading at runtime the older release installed with installp then fails. The bundled APR should have been built/installed alongside your httpd. Does your bin/envvars -- is it there and identified with LIBPATH in bin/envvars?

PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/opt/pware/bin TZ=PST8PDT LANG=C LOCPATH=/usr/lib/nls/loc NLSPATH=/usr/lib/nls/msg/%L/%N:/usr/lib/nls/msg/%L/%N.cat LC__FASTMSG=true
bin/envvars is a file of environment variables sourced by apachectl. What APR version does the LIBPATH in that file point to? What APR did your httpd build build against (config.log or stdout messages)
Please help us to refine our list of open and current defects; this is a mass update of old and inactive Bugzilla reports which reflect user error, already resolved defects, and still-existing defects in httpd. As repeatedly announced, the Apache HTTP Server Project has discontinued all development and patch review of the 2.2.x series of releases. The final release 2.2.34 was published in July 2017, and no further evaluation of bug reports or security risks will be considered or published for 2.2.x releases. All reports older than 2.4.x have been updated to status RESOLVED/LATER; no further action is expected unless the report still applies to a current version of httpd. If your report represented a question or confusion about how to use an httpd feature, an unexpected server behavior, problems building or installing httpd, or working with an external component (a third party module, browser etc.) we ask you to start by bringing your question to the User Support and Discussion mailing list, see [https://httpd.apache.org/lists.html#http-users] for details. Include a link to this Bugzilla report for completeness with your question. If your report was clearly a defect in httpd or a feature request, we ask that you retest using a modern httpd release (2.4.33 or later) released in the past year. If it can be reproduced, please reopen this bug and change the Version field above to the httpd version you have reconfirmed with. Your help in identifying defects or enhancements still applicable to the current httpd server software release is greatly appreciated.
