[GRASS-dev] Mac OS X newbie question

[William Kyngesburye]

I guess I interpreted this differently.  Just to be clear, do you  
mean you are connecting to a remote computer, where GRASS resides,  
from your Mac?  Or do you mean your Mac login & home is on a remote  
OSX server (LDAP), and GRASS is on the local Mac?

If it's a remote connection to GRASS, then it's as Glynn says.  You  
will also have to make sure that the X11 aplication is running.  I  
don't know if you can run it from a Terminal, you may need to use an  
xterm from X11.  Note also that OSX now defaults to the bash shell,  
so it would be .bashrc/.bash_profile.

If it's an LDAP login, then that doesn't matter.  There may be some  
things to put in the .bash_profile (DISPLAY, PATH), but if you use  
the OSX .app build of GRASS, this is taken care of for you.  GRASS  
6.3 has this, and I've ported it over for my 6.2 OSX binaries.  It  
also takes care of making sure that X11 is running and starts the  
Terminal for you.  Just double-click GRASS.app.

With a generic unix build, you'll have to start X11 yourself, and at  
least "export DISPLAY=:0.0" should be in your .bash_profile.


The X11 frowarding capability brings up an interesting point - when  
the Python gui is default, and NVIZ doesn't need X11, breaking the  
ties to X11 (on OSX at least), this won't be possible.  A more  
indirect method, like VNC, will have to be used.
