I would like to install the GRASS GIS addon r.pi within QGIS,

I only have access to basic GRASS commands

I installed QGIS using the osgeo4w-setup-x86_64.exe advanced installation using the http://osgeo4w-oslandia.com

Downloadsite and I installed GRASS GIS 7.4.1 where I was able to install four r.pi commands (r.pi.cor.mw, r.pi.grow, r.pi.lm, r.pi.rectangle) using following command:

g.extension extension=r.pi -s

but I need to compile the r.pi.prox (Calculation of Proximity and Modified Proximity Index for patches in buffer region).

The command:

g.extension extension=r.pi.prox -s


ERROR: Extension not found

And I don't know how to implement the extensions (Addons) in QGIS.

I think it is a compile error on our Windows build host for GRASS GIS Addons as g.extension should install all r.pi modules directly.

I have opened a ticket for that: https://trac.osgeo.org/grass/ticket/3642
