Hi,
I've got grass57 built now - thanks to everyone. When I try and start a graphics monitor i get the following (most recent weekly snapshot, Mac OS 10.2.8):
GRASS 5.7.-cvs:/usr/local/src/grass57_exp_2004_01_10/bin.powerpc-apple-darwin6.8 > d.mon start=x0
ERROR: Graph_Set: can't open Display
No socket to connect to for monitor <x0>.
Problem selecting x0. Will try once more
No socket to connect to for monitor <x0>.
Can anyone suggest what might be going wrong?
Thanks,
David
make sure you have the DISPLAY environment var set to :0.0
also make sure X11 is already running, if you're running GRASS from the Terminal instead of an X11 xterm.

There is a theory which states that if ever anyone discovers exactly what the universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarrely inexplicable. There is another theory which states that this has already happened.

David,
I don't know anything about the Mac OS, but my understanding is that
it is very unixish. If that's true, in addition to William's
suggestions, you might make sure you have permission to write to
wherever GRASS is trying to create the sockets. For example, on my
Linux box, sockets for user "ben" are created in /tmp/grass-ben. If
"ben" didn't have write permissions on /tmp, no socket(s) could be
created.
Regards,
Ben

There has been discussion on this recently on the R list. While OSX is
close to Unix, it isn't always right to think Unix means X. R users have
found that OSX will only sometimes set DISPLAY (so causing graphics output
to fail when needing a running X server - Apple provides alternatives I
think). The cases were predictable. Google "R" gets you to R, R-help
mailing list archives.

If the simple test is true - that X11 is running, then I'd suggest starting GRASS from an xterm (labelled "Terminal" in the Applications menu if you're using Apple's X11) instead of from the Terminal application, because then you know that the environment is set up for X11.
This can be slightly confusing because Apple has the Terminal application, which by itself is not X11 aware, but then Apple also calls xterms inside X11 "Terminal". But they are not the same. You CAN make X11 software work from the Terminal.app prompt, but it eliminates a possible source of error/confusion if you keep everything within the X11 Server windows.
If you are already trying this from an xterm (or maybe you know all this already, if so then sorry), or even if you have specific good reasons to not start GRASS from within X11, then the next step is to ensure that other X11 programs can create new windows - e.g. if, at the prompt, you enter xterm& as a command, does another window with a shell prompt start up ?
If not, then it is an X11 problem, and it's pretty safe to say the error has nothing to do with GRASS per se. You need to get a working X11 environment to be able to display GRASS monitors using the standard GRASS distribution. Probably the x11-users list hosted by Apple or the X-Unix mailing list would be more useful than this one to get this problem fixed, although I (or others here) might be able to help, too.
If other X11 applications have no trouble but GRASS still can't open a monitor, this list is definitely the place to be. It would be odd if the install process hadn't created the sockets and configuration files needed to start up a GRASS monitor, but.... ?
If "you know all this" still applies, I apologize, but more details are needed about your setup.
Cheers,
Scott
