error in grass.sh selecting python version

[foret37]

I am running Grass 7.0.0RC1 on a Mac OSX 10.10.2. I launched the program using the Grass app, and it failed with an error.

I then ran the script directly in the term, in order to see the error.

cd /Applications/GRASS/GRASS-7.0.app/Contents/MacOS/ ./grass.sh

Rebuilding Addon HTML manual pages index... Rebuilding Addon menu... Python 2.7.9 found. arch: posix_spawnp: /opt/local/bin/pythonw2.7: Bad CPU type in executable

This problem is well known, and has to do with the selection of the wrong version of python, as discussed at ​http://grasswiki.osgeo.org/wiki/MacOSX_GRASS_errors. Some sluthing showed that grass.sh selects a link in my MacPorts directory, /opt/local/bin, that points to the native Apple version of python. I followed the instructions at MacOSX_GRASS_errors and added the following environment variables: export GRASS_PYTHON=/usr/bin/python2.6 export GRASS_PYTHONWX=/usr/bin/pythonw2.6 but that did not fix the problem (same errors). After a lot of messing around, I found that I can get grass started by placing the directory with the right version of python as first in the path string: export PATH="/usr/bin:$PATH" Grass launches now, regardless of the status of the GRASS_PYTHON and GRASS_PYTHONWX variables. My casual reading of the grass.sh script suggests that it never checks GRASS_PYTHONWX to see if it has a value. That issue suggests that the solution to the problem is add a check for GRASS_PYTHONWX.

One other issue that seems odd: Grass does not remember my initial settings. In other words, each time I login, it goes through the questions for a new user.

Still an issue?
