This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was generated by GNU Autoconf 2.63. Invocation command line was

$ ./configure --enable-phalcon

I'm done. below is checklist to solve my issue before installation,

you should check what your current php version on your server by run "php -v"

1. if you server install multiple version of php, make sure you run the same version between "phpize" and "php-config"

cd /root/cphalcon/ext && [path to phpize] && ./configure --enable-phalcon --with-php-config=[paht to php-config] && make && make install

in my case

cd /root/cphalcon/ext && /usr/local/php56/bin/phpize --clean && /usr/local/php56/bin/phpize && ./configure --enable-phalcon --with-php-config=/usr/local/php56/bin/php-config56 && make && make install

2. config php.ini ( make sure you edit correct file ) add line "extension=[absolute path to]" or extension_dir = "[path to extension directory]" extension = ""

in my case : "extension=/usr/local/php56/lib/php/extensions/no-debug-non-zts-20131226/"

3. file ownership - directory related to phalcon might be "/usr/root/phalcon", "/usr/local/php56/include/php/ext/phalcon" . for me i set to 755
