I'm trying to install the v.stream.order extension for GRASS 8.2 from here:


But inspecting the zip file, it seems to be incomplete, with no .html document or .bat/exe file.

When installing through the GRASS Gui, I get this warning, and an error.

WARNING: No metadata available for module 'v.stream.order': Unable to fetch interface description for command '<v.stream.order>'.

Details: Cannot find the executable v.stream.order

ERROR: Unable to read manual page: [Errno 2] No such file or directory: 'C:\Users\... \AppData\Roaming\GRASS8\addons\docs\html\v.stream.order.html'

I'm using Windows 10 Business and plan to use the extension through the rgrass package.

Are errors on compiling extensions documented? Or is there a way of compiling an extension for windows? With some instructions for dummies :) ?

According to the addon log file at https://wingrass.fsv.cvut.cz/grass82/addons/grass-8.2.0/logs/

--> vector/v.stream.order FAILED log

There is a ctypes problem:

  File "C:\msys64\usr\src\grass820\dist.x86_64-w64-mingw32\etc\python\grass\lib\ctypes_loader.py", line 105, in __call__
    raise ImportError("Could not load %s." % libname)
ImportError: Could not load grass_vector.8.2.

I have opened an upstream ticket: https://github.com/OSGeo/grass-addons/issues/771
