I tried to set up Phalcon with these codes :
git clone --depth=1 "git://github.com/phalcon/cphalcon.git" cd cphalcon/build sudo ./install
But I got a warning, unfortunately. "configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers."
Although the installation is successful, unfortunately the phalcon is not active. When I restart Apache Server and look at php info, I see that phalcon is not active
Thank you for your help!
