"GRASS GIS should now be installed in c:\osgeo4w\apps\grass\grass-7.1.svn."



" To start GRASS use the icon on the desktop or if you want to be able to
use the command line from within GRASS.

Type in cmd console (assuming that we compiled GRASS 7.1):


"cmd console" is the OSgeo4W cmd console.

> "msys32\usr\src\grass_trunk\dist.i386-w64-mingw32\bin"

you are looking in the build directory, the install directory, as mentioned
above, should be e.g.
