[GRASS-user] gui wxPython2.5 and 2.6 problem on Mac, Path?

[William Kyngesburye]

GRASS on the Mac uses Python from a wrapper.  This is because wxPython (for the GUI) can't run 64bit, but that is what Python does on OSX 10.6.  So the wrapper forces it to run 32bit.  The GRASS startup will usually find the correct Python for the wrapper to use.  It will look in the order (always looking for the version it was compiled with):

GRASS_PYTHON
shell PATH
python.org Python in /Library/Frameworks
system Python

That /Applications python .command is probably for the python.org Python, which you must have installed at some time.  This will put the python.org Python before the system Pyhon in the shell PATH.

What does the rest of the startup output in the Terminal say?  (scroll up to see it)  It should identify which Python it found.

There should not be any problem with GRASS and Python 2.6, and the python version should agree with what wxPython was made for, which looks like 2.6 for yours.

Maybe something broke in a recent revision of GRASS?

I was looking which pyhton is in /usr/bin... there I found Python2.6 and Python2.5....It seems that they were probably in the wrong order in PATH i thought....in the Python2.6 folder in my Application ther was a file called "Update Shell Profile.command" and it was recommended in a forum to run that...

Theory of the Universe

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.
