[GRASS-user] GRASS7 - Error (python:14221): Gtk-CRITICAL - Ubuntugis-unstable

Thayse_Nery · July 5, 2015, 5:12am

Hi all,

I installed GRASS 7 and QGis from the https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable (Trusty 14.04) in Linux Mint 17.1 two weeks ago (sudo apt-get install postgis libgdal1h grass-dev grass-gui monteverdi2) and GRASS7 worked well for a week and now I have the following Error when I start the GRASS terminal:

Starting GRASS GIS…

(python:14221): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion ‘GTK_IS_WIDGET (widget)’ failed

I have uninstalled GRASS and installed again but I sill get the same error. How can I fix this error?

Further, QGIS doesn’t recognize GRASS7. Actually, I can see GRASS 7 on the QGis toolbox but it doesn’t work.
Is QGis prepared to support GRASS 7 through the QGIS/GRASS plugin? When I run the GRASS 7 from QGis toolbox I have the following Error:

GRASS_INFO_MESSAGE(14387,3): r.composite complete. Raster map created.

GRASS_INFO_END(14387,3)

Is possible to have GRASS 6.4 installed in parallel to GRASS 7? What would be the best way to have both GRASS 6.4 and GRASS 7.0 installed on Linux Mint 17.1 from repositories?

Many thanks for your help.

This is an unfortunately commonly seen message (also non-GRASS software).
Probably harmless. Do you observe any issues?

In Fedora they are gone - perhaps you need a newer GTK library version
(means: wait that Ubuntu updates it).

Further, QGIS doesn't recognize GRASS7. Actually, I can see GRASS 7 on the
QGis toolbox but it doesn't work.

To my knowledge work in progress... You can use GRASS GIS 7 in QGIS
via "processing" if you have a recent QGIS version installed.

Yes.

What would
be the best way to have both GRASS 6.4 and GRASS 7.0 installed on Linux Mint
17.1 from repositories?

I suppose to simply install them but I am not familiar with Linux Mint
(others here?).

Another option is to compile the code locally, some guide is here:
