Hello everyone,
As we will finally switch our GIS teaching to GRASS/QGIS, I now
need to help our professor to install these on her Mac OS X 10.4.10.
I decided to use 6.2.
I started with William's port at http://www.kyngchaos.com/software/
unixport/grass, first installing all the frameworks, then grass.
However, when I try to launch grass I get a message about there
being a problem with the wish command. A 'which wish' in a terminal
show /usr/bin/wish. Do I need to install another version of tcl/tk
for GRASS ?
My GRASS binaries include a bundled TclTk, this is the one that
should be used and it should be automatic, no need for env
settings. /usr/bin/wish is the Apple-installed TclTk and is old.
First thing to check: make sure X11 is installed, it's optional on
OSX. It's on the Tiger or system install disc - run the Optional
Installs installer, or find it in /System/Installation/Packages.
When you say GRASS/Qgis, note that my builds of Qgis, 0.8 and 0.9,
use GRASS 6.3.
So, several questions: any recommendation about which OS X port to
use ? What are the differences ?
Lorenzo made it possible to use an Aqua TclTk, which, if a missing
X11 is the problem, makes it possible to run without X11. But NVIZ
requires an X11 TclTk. It's possible to build it for Aqua (Lorenzo
may have done so), but it has problems. I gave up on Aqua TclTk
because it has cosmetic issues with layout (some serious) and there
are some controls that haven't been "Aquafied", so it just looks
strange. And with the move to Python for the GUI, I see no need to
pursue troublesome Mac-only bugs.
My package is universal. Lorenzo's is PPC-only, though it'll run
(slightly slower) with Rosetta translation on Intel Macs.
Lorenzo also includes lesstif and thus the xganim tool. I'm hoping
for a non-lesstif version of that (I think there is a TclTk script
version) and suggest running a series of images thru ffmpeg or other
video tool in the meantime.
There are a few extras in one or the other:
- Lorenzo includes ghostscript, for printing and creating ps output
it looks like. I don't know how much better that that is than using
builtin GRASS methods for generating postscript.
- I include some helper apps not in the OSX unix system and needed by
some GRASS commands - wget, gpsbabel, nnbathy (but not the GRASS
script extra), a few netpbm tools.
I got my build setup into the GRASS source (so I suppose it's
'official'). Anyone can create a GRASS.app just like mine. Even add
the missing lesstif/xganim.
