Support for Apache 2.4.17 - cannot load module - undefined symbol: ap_requires

[ngnanavadivel]

We are trying to use mod_auth_openidc on Apache 2.4.17.

Apache 2.4.17 declares that ap_requires has been removed.

When mod_auth_openidc is being loaded by Apache 2.4.17,
it is failing with the message
"Can't load module mod_auth_openidc" - undefined symbol : ap_requires.

Please fix this.

You're loading a module that was compiled for Apache 2.2 in to an Apache 2.4 server; where/which binaries did you get and which platform are you on?

[ngnanavadivel]

mod_auth_openidc-1.8.6-1.el6.x86_64.rpm is what we used.

https://github.com/pingidentity/mod_auth_openidc/releases/download/v1.8.6/mod_auth_openidc-1.8.6-1.el6.x86_64.rpm

Out platform is: RHEL 6.7
Distributor ID: RedHatEnterpriseServer
Release: 6.7

RHEL's stock Apache server is 2.2, that's what the stock rpm is compiled for as well; for customized installations with 2.4 you need to compile your own module from source.

I also get similar kind of error. undefined symbol: ap_get_exec_line. My Apache version is 2.4 and linux 7.

Make sure you haven't accidentally installed libapache2-mod-auth-openid instead of libapache2-mod-auth-openid*c*. (Aka the dark side of tab-completion.)
