Hi,
Just forwarding this tip from Markus, about the problem I've found in
OSGeo4W:
> On Sunday I made an installation on Windows and I found a problem. GRASS
> > 7.0.2RC is already available on OSGeo4W. However, the .bat file that is
> > created for the use of GRASS7 with QGIS, does not work, because it
> points to
> > the folder structure of GRASS 7.0.1.
>
> Hi Pedro:
> I'm not on the QGIS list, please forward to them that they would better
> use this approach to get the path rather than hardocing it:
>
> grass70 --config path
>
> If they need Python, they could use something like this:
>
>
> https://grasswiki.osgeo.org/wiki/Working_with_GRASS_without_starting_it_explicitly#Python:_GRASS_GIS_7
>
> # query GRASS 7 itself for its GISBASE
> startcmd = [grass7bin, '--config', 'path']
>
> p = subprocess.Popen(startcmd, shell=False,
> stdout=subprocess.PIPE, stderr=subprocess.PIPE)
> out, err = p.communicate()if p.returncode != 0:
> print >>sys.stderr, "ERROR: Cannot find GRASS GIS 7 start script (%s)" % startcmd
> sys.exit(-1)
> gisbase = out.strip('\n\r')
> # Set GISBASE environment variableos.environ['GISBASE'] = gisbase# the following \
> not needed with trunkos.environ['PATH'] += os.pathsep + os.path.join(gisbase, \
> 'extrabin')# add path to GRASS addons home = \
> os.path.expanduser("~")os.environ['PATH'] += os.pathsep + os.path.join(home, \
