How to fix error with xml2-config not found when installing PHP from sources?

Question

When I try to install php 5.3 stable from source on Ubuntu (downloading compressed installation file from http://www.php.net/downloads.php) and I run ./configure I get this error:

configure: error: xml2-config not found. Please check your libxml2 installation.

Answer 1

I had the same issue when I used a DockerFile. My Docker is based on the php:5.5-apache image.

I got that error when executing the command RUN docker-php-ext-install soap

I have solved it by adding the following command to my Dockerfile:

RUN apt-get update && apt-get install -y libxml2-dev

Answer 2

OpenSuse

"sudo zypper install libxml2-devel"
