We would like to send this report automatically to the
PHP QA team, to give us a better understanding of how
the test cases are doing. If you don't want to send it
immediately, you can choose "s" to save the report to
a file that you can send us later.
Do you want to send this report now? [Yns]: y

Posting to qa.php.net /buildtest-process.php

Thank you for helping to make PHP better.

7)Then you can find a file "pcntl.so" under the directory "/usr/lib64/php/modules/"

8)Then go to php source directory "/root/php-5.2.13 " then execute ./ configure command for enabling --enable-pcntl \ module
./ configure --enable-pcntl

./configure --enable-bcmath--enable-calendar--enable-exif--enable-ftp--enable-gd-native-ttf--enable-libxml--enable-magic-quotes--enable-mbstring--enable-sockets--prefix=/usr/local--with-apxs2=/usr/sbin/apxs--with-freetype-dir=/usr--with-gd--with-imap-ssl=/usr--with-jpeg-dir=/usr--with-kerberos--with-libxml-dir=/opt/xml2/--with-mhash=/usr/lib64/--with-curl=/usr/lib64/--with-gettext--with-mcrypt=/opt/libmcrypt/--with-mysql=/usr--with-mysql-sock=/var/lib/mysql/mysql.sock--with-openssl=/usr--with-openssl-dir=/usr--with-png-dir=/usr--with-ttf--with-xpm-dir=/usr/X11R6--with-zlib--with-zlib-dir=/usr--enable-pcntl

Then execute make and make test command.

9) Then add extension entry in php configuration file (php.ini)

vi /etc/php.ini
extension=pcntl.so

10) Restart Apache service

That's it . You can verify the phpmodules by executing the php -m command.
