I downloaded and installed Quantum GIS 1.5.0 with GRASS using the OSGeo4W installer on my Windows XP machine. Unfortunately, when I go to Plugins>Manage Plugins I cannot find the GRASS plugin. When I browse to OSGeo4W\apps\qgis\plugins I can see grassplugin.dll, grassrasterprovider.dll and grassprovider.dll. So, I would appreciate it if someone could tell me how to make QGIS recognize the GRASS install.

  • Is GRASS itself installed via OSGeo4W? Do you see other plugins?

  • What do you see if you go to Plugins>GRASS? I see 4 plugins enabled, but the rest are grey'd-out. I haven't installed GRASS though.

    David, I do not have an option for GRASS in my Plugins menu, and it does not show up in Manage Plugins...

I just installed QGIS 1.5.0 two days ago. The GRASS plugin shows up in my Plugin Manager and under the Plugin Menu. I used the Standalone Installer though, rather than the OSGeo4W Installer. You might want to try that route. (http://www.qgis.org/wiki/Download)

You also have to set up a GRASS Database through the "Plugins > Grass > New Mapset" menu in order to get the other GRASS Plugin Menu items to become active.

  • Thanks! That did it. Apparently there is some issue with the OSGeo4W installer and the GRASS plugin.

See also the draft "QGIS GRASS Cookbook" which is available here: http://grass.osgeo.org/wiki/QGIS_GRASS_Cookbook

In the long run it should go into the QGIS user manual as well.
