phpize Configuration Challenges

Installation and Configuration Issues

When attempting to install ffmpeg as a PHP extension, you may encounter the error "Cannot find config.m4." This error indicates that phpize cannot locate the necessary headers within your PHP setup. Here's a closer examination of the situation and how to resolve it.

Missing Dependency

The absence of config.m4 suggests that you have not correctly installed the necessary PHP development package. Typically, you would need to install php5-dev in your case, as indicated by your sudo apt-get install php5-dev command.

Solving the Dependency

Depending on your Linux distribution, you may need to install a different package:

• Debian/Ubuntu: Install the php-dev dependency package (e.g., sudo apt install php-dev).
• RHEL/CentOS/yum: Install the php-devel package (e.g., yum install php-devel).

Once you have installed the appropriate dependency, retry running phpize. This should install the required headers and resolve the missing config.m4 issue.
