Processing QGIS Zonal Stats broken on Windows

Added by Giovanni Manghi over 8 years ago. Updated over 8 years ago.

Status:	Closed
Priority:	Severe/Regression
Assignee:	Victor Olaya
Category:	Processing/QGIS
Affected QGIS version:	master	Regression?:	No
Operating System:	Windows	Easy fix?:	No
Pull Request or Patch supplied:	No	Resolution:	fixed/implemented
Crashes QGIS or corrupts data:	No	Copied to github as #:	22811

Description

Seems only Windows is affected (the last working release seems to be 2.6).

Try this project

https://github.com/qgis/QGIS-Documentation/tree/master/source/docs/training_manual/exercise_data/processing/more_backends

You'll get

[processing] add support for GDAL 2.x in raster tools (refs #14858)

History

#1 Updated by Alexander Bruy over 8 years ago

Tested with geomorpho.qgs project (more_backends.qgs seems does not have any raster layers in it) under Windows using latest qgis-dev package — no errors, statistics calculated correctly. I got same results as under Linux.

#2 Updated by Alexander Bruy over 8 years ago

Issue with 2.8.9 confirmed, I also got

weird you don't get errors in 2.14 or master, I have clean testing environments on windows and I see the same on both OSes.
