QGIS » QGIS Application

Seems to be related to the standalone installer only, while the OSGEO4W 64 bit installed version works for me. See also https://gis.stackexchange.com/questions/246022/unable-to-run-any-grass-7-algorithms-in-qgis-2-18-10-on-windows-764

Once you set the GRASS7 path to OSGEO4W64, standalone QGIS works for me too.

Furthermore, the GRASS 7.2.1 GUI icon only works from OSGEO4W, while the icon from standalone causes a crash after selecting location and mapset. This is the error log from GRASS GUI:

WindowsError: [Error 126] Das angegebene Modul wurde nicht gefunden

Although I used the Icon "QGIS Desktop 2.18.10 with GRASS 7.2.1", I have no Grass plugin available. Form the startup log:

2017-07-03T11:12:42    1    Konnte C:/PROGRA~1/QGIS2~1.18/apps/qgis/plugins/grassplugin7.dll nicht laden (Grund: Die Bibliothek C:/PROGRA~1/QGIS2~1.18/apps/qgis/plugins/grassplugin7.dll kann nicht geladen werden: Das angegebene Modul wurde nicht gefunden.)

The missing dll files however are in the folder /apps/qgis/plugins.

So it is not only processing that fails.

No errors and GRASS plugin available in the C:\Osgeo4W64 installation.

I'm experiencing the same problem. I do not use the grass-toolbar, hence I use processing.runalg("grass:v.voronoi", parameters). On startup I also gets:

2017-07-06T06:37:12 1 Failed to load C:/OSGEO4~1/apps/qgis/plugins/grassplugin7.dll (Reason: Cannot load library C:/OSGEO4~1/apps/qgis/plugins/grassplugin7.dll: The specified module could not be found.)

The .dlls are in the specified folder :(

Not only in standalone version, also in the osgeo4w installation.

Confirmed also GRASS no working in Processing:

This algorithm cannot be run :-(
It seems that GRASS GIS 7 is not correctly installed and configured in your system. Please install it before running GRASS GIS 7 algorithms.

Maybe a issue in GRASS in OSGeo4W. Apparently it's linked against a old version of GDAL. See https://lists.osgeo.org/pipermail/grass-user/2017-July/076735.html

Hi Jurgen,
installing gdal201dll in osgeo4w helps indeed and makes GRASS work again.

Is this really an upstream (GRASS) issue or the ball in our side?

OSGeo4W not GRASS.

But it of course depends on your angle. OSGeo4W packaging of GRASS is done by Martin Landa of GRASS and QGIS in OSGeo4W is packaged by me. So the people to blame are the same - you just have to catch them with the right hat on ;)

Anyway, I added a dependency to the grass package in osgeo4w - so the missing dll should be installed automatically now.

OSGeo4W not GRASS.

yes sorry I meant that.

Anyway, I added a dependency to the grass package in osgeo4w - so the missing dll should be installed automatically now.

so I guess that if the next 2.18 point release will contain the same dependency we can close this, right?

Yes.

OSGEO4W worked for me, because gdal201.dll was still present from an earlier install.

Anyway, to get QGIS 2.18.10 standalone running too, you can copy C:\OSGeo4W64\bin\gdal201.dll to C:\Program Files\QGIS 2.18\bin

or extract gdal201dll-2.1.3-2.tar.bz2 (32bit) or (64bit) to C:\Program Files\QGIS 2.18\ (or run setup.bat from C:\Program Files\QGIS 2.18\bin to install the package).

I deleted and installed the new 2.18.11 version and it still fails to load the 3 existing plugins. I tried to add the gdal201.dll to C:\OSGeo4W64\bin\ but it didn't help.

did you installed the qgis-grass7-plugin package?

I changed the folder name to osgeo4w (from osgeo4w64)

I would not have done that. Anyway, with the osgeo4w installer is safe to remove the c:\osgeo4w folder (or osgeo4w64 depending on your installation) and then relaunch the installer and install what you need. If the packages are already downloaded locally it would not download anything again, so it is a fast procedure.
I would also clean qgis/osgeo entries in your Windows registry with regedit.exe

I removed the catalog again, removed all occurrences of qgis in regedit and the temporary downloads (in AppData/local) and installed a fresh version of osegeo4w(64) with both grass version 6 and 7, when I started QGIS I got following errors in the plugin:

I have the feeling that I'm lacking some lib or why can't it find the existing dlls?
