mod_auth_openidc installation error on Apache 2.2.27

[jiang-ziqiang1]

We are trying to use mod_auth_openidc on Apache 2.2.27. （CentOS Linux release 7.6）
mod_auth_openidc version is 2.4.10.
I excuted '/configure' with parameters and it was finished successfully.
but when I excuted 'make' I got a error message as below.
