[GRASS-dev] [GRASS-user] experimental Python 3 support in trunk

[Markus Neteler]

Hi,
(reducing to grass-dev)

... while I wanted to test, my box fails on "pip install wxpython" in
the virtualenv-3:

pip install wxpython
[...# 30min later: ...]
...
    Finding libs for WXAUI                                             : yes

Any idea?

When simply ignoring the GUI for now:

(grasspy3) [mneteler at oboe ~ ]$ python3 ~/bin/grass76
Traceback (most recent call last):

(same error as Martin)
