Question

i have been seeing these errors whilst attempting to build, i am attempting to build a standalone executable but with little success, can someone please advise?

 undefined reference to `ap_get_server_name'
 undefined reference to `apreq_handle_apache2'
 undefined reference to `ap_hook_child_init'
 undefined reference to `ap_get_server_port'
 undefined reference to `ap_hook_handler'
 undefined reference to `ap_hook_post_config'
 undefined reference to `ap_log_error_'
 undefined reference to `ap_get_brigade'
 undefined reference to `ap_rwrite'

This is mostly what my makefile contains:
