how to install and run phpize

Question

I have been meaning to install ffmpeg as an extension to my php setup. So before I can install it, I need to phpize it. I installed php5-dev by sudo apt-get install php5-dev But now when I run phpize I get the following error :

phpize
Cannot find config.m4. 
Make sure that you run '/usr/bin/phpize' in the top level source directory of the module

The location of my php.ini is /usr/local/zend/etc/php.ini

From another online resource i tried this

sudo apt-get install autoconf automake libtool m4

But all of them are already installed.

Locate config.m4 didnt return anything.

Any pointers here how I can get phpize and thus, ffmpeg up and running ?

For ubuntu 14.04LTS with php 7, issue:

sudo apt-get install php-dev

Then install:

pecl install memcache

Answer 2

Of course in PHP7.2

sudo apt-get install php7.2-dev

Answer 3

For instance, if you wanted to use the "phpize" command for PHP 5.6, you would use the full path: Code:

/opt/cpanel/ea-php56/root/usr/bin/phpize
