Re: [GRASS-user] GRASS GIS 8.0.0 Stand Alone

Hi Martin,

please create an issue:
https://github.com/OSGeo/grass/issues/new/choose

Indeed, looks like the URL on the server doesn't match the url g.extension
expects. Note that you are using a daily build, you may want to consider
using released GRASS 8.0.0.

[GRASS-user] hexagon rasters

[Ken Mankoff]

Hello List,

I'm interested in working with hexagonal rasters. I know I can make hexagon 
vectors with "v.mkgrid -h", but is there any way to then work with these in 
raster space? I'd like to use r.walk and r.cost to estimate costs to move 
around the hex grid.

Thanks,

  -k.

Re: [GRASS-user] GRASS GIS 8.0.0 Stand Alone

[Martin Bittens]

Hello GRASS User,

here comes an update concerning the installation of GRASS GIS addons:

In the meantime I could change the addon-download link provided by
GRASS. Using some of the 'recipes' I found in the internet I manipulated
the g.extension.py file in line 1442 by adding " patch='dev' " and
deactivating " patch=version[2] ". As a result, GRASS GIS is now calling
'/grass80/addons/grass-8.0.dev' for the download of addons. It´s not a
very professional solution because each time when the addon's web site
changing its address (what happens as far as I know with each GRASS
update) I have to made the respective adjustment in g.extension.py. But
for know it is working.

But...! The addon installation is obviously working only for addons
which are based on python scripts (e.g., v.centerline.py). Addons which
come with an exe-file are being installed with error messages and don´t
work:

g.extension extension=v.centerpoint operation=add
Downloading precompiled GRASS Addons ...
Fetching  from

(be patient)...
Updating extensions metadata file...
Updating extension modules metadata file...
WARNING: No metadata available for module 'v.centerpoint': Unable to
fetch interface description for command ''.

Details: 
Installation of  successfully finished
(Mon Feb  7 16:49:42 2022) Command finished (19 sec)


So, what is the correct way for installing the GRASS GIS addons?


Regards


Martin

Hello GRASS User,

I just installed the latest GRASS GIS Stand Alone version (8.0.0). When
I tried installing some addons I always received an error message:

ERROR: Cannot open URL:
http://wingrass.fsv.cvut.cz/grass80/addons/grass-8.0.0dev/v.centerpoint.zip


I checked the web site and could the that there only exist 2 versions:

- /grass80/addons/grass-8.0.dev

- /grass80/addons/grass-8.0.0


How I can change the web address GRASS GIS is calling to the ones which
are providing the addons?


Thank you very much for a suggestion.


Regards


Martin
