pdo_mysql.so warning for php-fpm

[Mahmood Naderan <mahmood.nt@xxxxxxxxx>]

Hi,

On php 5.3, I have this php.ini

ubuntu@fr13:~/php-5.3.29$ cat /usr/local/lib/php.ini
[Session]
session.save_path="/tmp/http_sessions"
extension="apc.so"
extension="pdo_mysql.so"
extension="odbc.so"
extension="curl.so"
extension="memcache.so"
extension="gd.so"
file_uploads = On
upload_tmp_dir = /tmp
error_reporting = E_ALL
display_errors = Off
log_errors = On
safe_mode = 0
short_open_tag = On

I also have set PHPRC as below

ubuntu@fr13:~/php-5.3.29$ echo $PHPRC
/usr/local/lib

when I run php-fpm, I get these warnings

ubuntu@fr13:~/php-5.3.29$ sudo /usr/local/sbin/php-fpm

I have searched about these messages, however, it is not clear what is missing. Who should create pdo_mysql.so?
