hello, debian stretch I follow this tuto: https://www.howtoforge.com/tutorial/how-to-install-php-7-on-debian/#-enable-memcache-optional-2 Configure and build the PHP memcache extension. ./configure --with-php-config=/opt/php-7.2/bin/php-config but this line does'nt work : make: *** Pas de cible spécifiée et aucun makefile n'a été trouvé. Arrêt. make make install Do you an idea to activate memcached: If I try telnet localhost 12345 telnet: Unable to connect to remote host: Connection refused Thank you
