Any special reason why you want to use the cygwin version ? The native windows versions have become pretty good by now. At Moritz’s suggestion I have downloaded ncurses - indeed, the full Utils package - from Cygwin. And the two error messages, of which I was complaining, have disappeared. MORITZ IS A GENIUS But, gis.m still does not work. It looks as though the default Cygwin download, which is not a full download, is not enough. I was hoping to use Cygwin because most of the online tutorials assume a Unix environment. Some of the tutorials are themselves tar.gz files. And Marcus’s book is quite expensive. I don’t want to buy the book unless the Cygwin/Grass combination works. So I have started using the native Windows version of Grass, at first with the Spearfish60 data. And I have made some progress. But ‘d.vect roads’ does not change what I see on the screen. It creates a file called ‘map.png’. Sorry to keep asking for help, but how do I display the ‘roads’ map in a window? |

No, I was just the one who answered...

Did you follow the instructions here:
http://grass.osgeo.org/grass62/binary/mswindows/
and here:

?

I don't think that the Unix environment is so much of an issue, but rather the use of the command line. For an introduction to the GUI, you should start by reading [1] and [2]. You can also try some of the tutorial listed on the OSGEO education material website [3].

Yes, the command line d.* commands used in the tutorials all suppose the existance of X-monitors. These do not work on Windows, however, (and do not exist in grass7 anymore, BTW) and all display has to either through the GUI (either tcltk-based or the new wxpython-based) or directly into a file (actually the GUI also just displays the content of files).
If you want to follow the tutorial from the command line, you should find a viewer which will automatically update a file which has changed. You can then point it to map.png and just leave it open while you experiment with the d.* commands. You will probably have to set the environment variable GRASS_PNG_READ=TRUE, so that each d.* command doesn't erase the results of the previous one. I personnally use gqview for which there is a Win port [4], but there's tons of others.
You can also try the internal ximgview [5], but I don't know if this works in the windows version, nor if it is included in any of the 6* binaries.
