Я установил pcntl на моем PHP 5.4.6, работающем на Ubuntu 32-bit 12.10, используяэтот статья.

Это невсе идет гладко, потому что после компиляции при запускеmake test Я получил следующие ошибки. Я получаю предупреждение каждый раз, когда яЯ пытаюсь развить дочерний процесс, который говорит:

Предупреждение: pcntl_fork () был отключен по соображениям безопасности в /var/www/mydev/dev/mailServiceTest.php в строке 8I '

я искал решение по всей сети, но, к сожалению, я не нашелЯ не могу найти упоминания этой проблемы где-либо еще.

    Build complete.
Don't forget to run 'make test'.

Thank you for helping to make PHP better.
oleg@oleg-Lenovo-G580:/php/php-5.4.6/ext/pcntl$ version

При вводе следующей команды кажется, что PHP действительно уже установлен, хотя интерпретатор PHP не сделалt распознать функцию до того, как я установил это расширение вообще:

oleg@oleg-Lenovo-G580:/php/php-5.4.6/ext/pcntl$ php -m | grep pcntl
PHP Warning:  Module 'pcntl' already loaded in Unknown on line 0
pcntl

Как я могу настроить эту функцию для правильной работы?
