The root cause may be that virtualenv's list of built-in modules is much smaller than the system python's list. I didn't find a way to solve this issue [1]. so I'm not sure that virtualenv will be a helping solution to test python3 in winGRASS.

We already know many things don't work with Python 3 at all - I'm thinking about all things dependent on ctypes - so we would seriously reduced the functionality for the people who are using trunk for real work (so far we always had people doing it and supported that AFAICT). We are now getting some testing done and in some time, when Python 3 support is more complete and/or we are not getting enough testing, we can change the shebang. So far it seems to be that the Python virtual env works and, alternatively, changing PATH (perhaps together with creating a symlink) should work too. Also those who needed to workaround that they distro has python -> python3 symlink don't need to do the workaround anymore.

I think we can have something like "technical preview" in 7.8 (e.g. with warning "use 3 only if you have to"). 8.0 should fully support 3. Another thing is that Python 3 means using wxPython 4 to get the GUI (other wxPythons don't support Python 3). That was hard to do for quite some time (4.0.0 released in January), but now it is included, e.g., in Ubuntu 18.04 (released April). As for the shebang, PEP394 says: "for the time being, all distributions *should* ensure that python, if installed, refers to the same target as python2, unless the user deliberately overrides this or a virtual environment is active" and that "python should be used in the shebang line only for scripts that are source compatible with both Python 2 and 3" which is what we aim for.

as I said, that's the ctypes problem, weird is I don't get this specific

You are right, solved with that.
Here a few more issues: At wxGUI startup:
### in the terminal:
07:37:09: Debug: Adding duplicate image handler for 'Windows bitmap file'
07:37:09: Debug: Adding duplicate image handler for 'Windows bitmap file'
--> perhaps from an underlying lib?
### in the wxGUI console:

Reason: name 'WindowsError' is not defined
Note that the wxGUI's vector digitizer is disabled in this
installation. Please keep an eye out for updated versions of
GRASS. In the meantime you can use "v.edit" for non-
interactive editing from the Develop vector map menu.

Thanks, that is on Fedora:
webkit2gtk3-devel
Now I got also wxpython compiled (30min of compilation on my laptop).
Now the wxGUI start screen comes up.

Hi,

my first attempt to start GRASS fails with:

Is it expected? Ma

Python3 support will be crucial for GRASS in a near feature. Will help with testing.
