I am using GRASS GIS 7. When I try to install "v.kriging" module using "g.extension" command, it is not installed. Though it says that the extension is successfully installed, I get the error "'v.kriging' is not recognized as an internal or external command, operable program or batch file."

I then tried to get the code from the following link:

http://wingrass.fsv.cvut.cz/grass70/addons/grass-7.0.1RC2/

But all folders in v.kriging.zip are empty.

Can you help me with installing the extension on Windows 8.1?

In general, you can see the availability status of Addons here: https://grass.osgeo.org/download/addons/ --> Available Add-ons --> List of GRASS GIS 7 Add-ons (build status for Linux and Windows)

Being the GRASS GIS web site admin, I've seen that LAPACK support was missing on the Linux build server, now fixed (not relevant for you, though).

Concerning the winGRASS side, you need to have the LAPACK and BLAS libraries installed and GRASS GIS compiled with support for it enabled since v.kriging uses matrix functions from those libraries. I suspect that these libraries are also lacking on the winGRASS build server, will contact the admin for that.

  • Thanks for the reply. Now I have installed LAPACK and BLAS libraries. Still I get the same error. In this link, the status of v.kriging is given as failed. Does it mean that the module will not work on Windows? – GISstudent Sep 28 '15 at 13:00

    You need to use --with-blas and --with-lapack in the configure step, then compile GRASS GIS on Windows. We plan to ship winGRASS in the near future with LAPACK/BLAS support but this will need some time to update the server... – markusN Sep 28 '15 at 22:45

    Can you please explain in detail on how to compile and install GRASS with blas and lapack. I have downloaded liblapack.dll and libblas.dll for windows. I'm pretty new to GRASS GIS and I have no idea what "--with-blas" and "--with-lapack" means. Can you please help me with the installation? – GISstudent Oct 10 '15 at 15:55
