We are upgrading apache httpd version from 2.2.34 to 2.4.39 . As part of this upgrade process, we need to load  mod_cluster modules(mod_proxy_cluster,advertise,mod_manager) modules . We have downloaded mod_cluster-1.3.10.final file. During building of these modules source code into .so file, we need to execute configure command as below.

./configure --with-apxs=/usr/bin/apxs

We are getting the error as below.

"checking for Apache httpd installation... APXS is /usr/bin/apxs

apxs_support is false

configure: error: mod_cluster module need a valid apxs"

apxs already available  in the path /usr/bin/apxs. Please find the output of whereis apxs command.

# whereis apxs

apxs: /usr/bin/apxs /usr/share/man/man1/apxs.1.gz
