I use Travis CI build matrix to phpize/configure each time for now.

Is that correct? ------------------------------------------------------------------------ [2018-02-14 10:38:13] serghei at phalconphp dot com Hello nikic, Here is config.log http://vpaste.net/UDArc ------------------------------------------------------------------------ [2018-02-12 12:10:20] nikic@php.net Sorry, the name of the file is config.log, not configure.log.
