Target version:   2.3.11-beta
OS:               ubuntu 16.04
Pcre version:     8.11 / 8.42
Command I use: ./configure
                   --with-included-apr 
                   --with-included-apr-util 
                   --with-pcre=/usr/local/bin/pcre-config 
                   --with-pcre-dir=/tmp/httpd-2.3.11-beta/pcre-8.11
               ('--with-included-apr-util' and '--with-pcre-dir' maybe invalid)
               make
Error I get:

All is right when compiling 2.4.xx

So should I include those function manually or what have I missed?

Please help, thank you!
