Update: you are right -- it works on XP, but I am on Windows 7.<br>
While installing on Cygwin the packages required to compile GRASS, it
occurred to me I had read on Cygwin website that Windows 7 would have
been supported starting next major version 1.7 (see
<a class="moz-txt-link-freetext" href="http://cygwin.com/">http://cygwin.com/</a>). However, 1.7 is in beta testing and available to
install, which I did. Things work much better, and now GRASS 6.4.0RC5
starts up fine with tcltk gui.<br>
<br>
First problem I encountered next is with the dbf driver. The output of <i>db.connect
-p</i> seems ok:<br>
<br>
driver:dbf<br>
database:$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/<br>
schema:<br>
group:<br>
<br>
But when I do <i>db.test test1</i> errors arise:<br>
<br>
create table grass_test1 (i1 integer, d1 double precision, c1
varchar(20))<br>
EXECUTE: OK<br>
insert into grass_test1 values ( 1, 123.456, 'abcd' )<br>
EXECUTE: OK<br>
insert into grass_test1 values ( 2, null, 'xxx' )<br>
EXECUTE: OK<br>
select * from grass_test1<br>
EXECUTE: OK<br>

Any idea what happens and/or testing hints for better diagnosis?<br>

If you compile from source, even if you have problems with the
resulting binaries, it will be easier to debug such problems with
debug info.
The Cygwin binaries on the GRASS website have been stripped, as
unstripped binaries are over twice as large, which is inconvenient
both for me and for anyone downloading them.
FWIW, I configured with:
./configure
--with-includes=/usr/local/include
--with-libs=/usr/local/lib
--with-proj-share=/usr/share/proj
--with-cxx
--with-freetype
--with-opengl
--with-readline
--with-nls
--without-odbc
--with-cairo
--with-sqlite
--with-blas
--with-lapack
--with-postgres
--with-cairo-includes=/usr/include/cairo
'--with-cairo-ldflags=-lcairo -lX11'
--with-freetype-includes=/usr/include/freetype2
--with-python
--with-motif
--with-glw
[I need /usr/local/{include,lib} for GDAL and Tcl/Tk.]
For a basic GRASS installation, most of the above --with-* switches
aren't needed. As I was building a package for distribution, I
included every option which I could get to work.
