来自终端的未定义函数mysql_connect（）

Question

I have recently installed pthreads in my machine(ubuntu 12.04 LTS 32bit) and thereafter mysql_connect() is not working from terminal(via CRON JOB as well). But then working fine through browser.

I followed these steps to install pthreads

# Required libraries
sudo apt-get install gcc make libzzip-dev libreadline-dev libxml2-dev \
libssl-dev libmcrypt-dev libcurl4-openssl-dev lib32bz2-dev 

# Download PHP
cd /usr/local/src

wget http://www.php.net/distributions/php-<version>.tar.gz
( e.g. wget http://www.php.net/distributions/php-5.5.8.tar.gz )

# Extract
tar zxvf php-<version>.tar.gz
(e.g. tar zxvf php-5.5.8.tar.gz )

# Configure
cd /usr/local/src/php-<version>
( e.g. cd /usr/local/src/php-5.5.8 )

./configure --prefix=/usr --with-config-file-path=/etc --enable-maintainer-zts

# Compile
make && make install
( make -j3 && make -j3 install) -> Faster building

# Copy configuration
cp php.ini-development /etc/php.ini

# Install pthreads
pecl install pthreads
echo "extension=pthreads.so" >> /etc/php.ini

# Check installation
php -m | grep pthreads

Note : Previously I was using PHP 5.3.10. Now with this installation upgraded to PHP 5.5.8. Also I tried adding

extension=mysql.so

into the php.ini file in following locations as well.

/etc/php5/apache2/php.ini

/etc/php5/cli/php.ini

Thanks in advance

Should read more like:

./configure --prefix=/usr \
            --with-config-file-path=/etc \
            --enable-maintainer-zts \
            --with-mysql=mysqlnd \
            --with-mysqli=mysqlnd \
            --with-pdo-mysql=mysqlnd

See:

./configure --help

For options.

Note that mysql is deprecated, use mysqli or pdo-mysql instead
