Errors compiling PHP 7.2 from source on a Raspberry Pi

Published Jan 12, 2019

The PHP version used is 7.2 directly from the git repository from github. Newer version might not work as expected. The version used to compile is the Raspbian (Raspbian Stretch with desktop and recommended software):

Version: November 2018
Release date: 2018-11-13
Kernel version: 4.14

Getting the source code

git clone https://github.com/php/php-src

Entering the cloned repository to start the compilation process

cd php-src

Change to the version 7.2 (maybe newer or older, as you wish)

git tag php-7.2.0
