Compile and build QMapShack with PROJ 8 for Linux Mint 20.1

QMapShack versions beyond version 1.15.2 will use PROJ version 8. This requires some changes in the QMS build procedure. This page is an early release of the description of these changes for Linux Mint 20.1. The information on this page was contributed by anesthesia. It can be used to build current QMS development versions.

Basic information about the compilation of QMapShack for Linux Mint can be found here. This page describes only the changes required when using PROJ 8.

Warnings and hints:

  • GDAL version 3.x now depends on PROJ. Therefore, don't change the described installation sequence of packages.
  • If there are older versions of the used libraries on your system, remove them completely first.
  • Don't change the advised directory settings.
  • Part of a German description of the installation procedure is a template for a shell script which can be used to run all steps.
