Quick start

Instructions for a user on how to get the plugin working. First section deals with QGIS, and what versions are best to work with. This is followed by a section on how to install the CPLUS plugin, ending with a short tutorial accompanied by a video to show the user how to use the plugin.

QGIS version

The CPLUS plugin might have issues with older versions of QGIS. QGIS 3.32 or higher has thoroughly been tested with no major known issues. Here is a list of possible issues which may occur if using an outdated version of QGIS are being used:

  • Processing stalls and does not continue
  • Symbologies (e.g. colour ramps) cannot be applied to the output layers
  • Reports cannot be generated

Best will be to update QGIS to the latest version, even for other plugins, as bugs and improvements will be available for those versions. To update QGIS, a user can do the following:

  • Go to the QGIS download webpage
  • Download or follow the instructions for the OS on which QGIS needs to be installed
  • If a specific version (not the latest version) of QGIS needs to be installed, click on the All releases tab

OSGeo4W network installer

This section will only be helpful for Windows users. The OSGeo4W network installer provides much more option in a user-friendly UI. Advantages of using this installer:

  • Easily allows a user to install both the latest and the latest LTR versions of QGIS
  • User can select the exact libraries and versions they want to install (e.g. gdal)
  • Option to include (or not include) GRASS and SAGA
  • Extensions for QGIS
  • If a user wants to update an existing QGIS installation, simply run the osgeo.exe in the installation directory
  • Simply run the osgeo.exe to update already installed libraries, or install new libraries
  • Easy to remove libraries or extensions
  • Python modules
  • And much more
