Building on CentOS Stream

This document provides users with step-by-step instructions on how to compile and usemod_tile and renderd.

Please see our Continuous Integration script for more details.

A Docker-based building & testing setup pipeline is also available here for your convenience.

CentOS Stream does not provide a mapnik/mapnik-devel package, so it will first need to be built & installed, which is beyond the scope of this document, please visit the project's installation document on GitHub or our Continuous Integration script for more information.
