[GRASS-dev] New attempt to update GRASS for Mac

Fri Jul 28 15:24:30 PDT 2017

A bit more information.

The grass.sh.in script tries to find a pythonw file to use for Python. It checks the setting of GRASS_PYTHON, then it looks in standard places for system Python.

The script also seems to set GRASS_PYTHONWX to the value of GRASS_PYTHON after it searches for a useable Python. It says it is trying to find the Python needed by wxPython, but I can see no code that actually checks wxPython. It simply sets GRASS_PYTHONWX to whatever Python it has found, with "pythonw" as a default.

And then after all this, it resets GRASS_PYTHON on lines 203 and 204

GRASS_PYTHON="python"
export GRASS_PYTHON

So all of the prior code is pretty much moot as far as the GRASS_PYTHON environmental variable is concerned. Unless there is some program flow that I'm missing something in the program flow, this default should be set only if no other Python is found.

There is also a setting in this script:

GRASS_WXBUNDLED=
export GRASS_WXBUNDLED

This seems potentially useful, but does not seem to be used elsewhere.

I was able to track this down.

I was setting GRASS_PYTHON to ../anaconda/bin/python

The grass.sh.in script for Mac OS is set up to only accept "pythonw" for the path to python, not "python".

Once I changed my .profile to include the line:

export GRASS_PYTHON="/Applications/anaconda/bin/python"

Grass launches with this as the default.

Still trying to figure out how GRASS_PYTHONWX works in this script.

Previously, we needed to set this path to compile GRASS so that it worked with wxPython wrappers for wxWidgets. I will do a new compile without this argument and see what happens.

In any case, I need to be able to make sure that GRASS uses the wxPython that is bundled with it by default to avoid differences in versions and SIP issues.

And I can't yet find anything that seems to serve the same function. I can put in a path to the folder/directory where the wxPython 4 files live. While this compiles without error, I don't think it is using wxPython 4.

--with-wxwidgets= is for wxWidgets (C++ library), not wxPython (its Python wrapper), so you don't need to use at all. wxPython must be part of the Python installation you are using.
