Hi,

any chance that you update to the much more modern GRASS GIS 7.8?

Compile & install ok

The gui is working.

BUT my scripts does not work any more. See belows errors :

Traceback (most recent call last):
File "/usr/local/grass78/gui/wxpython/gui_core/forms.py",
line 2866, in ParseCommand

[...]

name 'unicode' is not defined

----------------------------

If I add # -*- coding:UTF-8 -*- on first line in /usr/local/grass78/etc/python/grass/lib/gis.py and /usr/local/grass78/etc/python/grass/lib/raster.py my scripts work !

Interesting!

Is-it the good fix ??

It would follow:
https://www.python.org/dev/peps/pep-0263/#defining-the-encoding

The file is generated by ctypesgen.py to wrap C, I am not sure how the
encoding could be added there.
Could you open a ticket here?
https://trac.osgeo.org/grass

with the information (+ the Locale you use, is it US or French or...?).

Hi

I had (and still have) a similar problem that I began experiencing when I updated to 7.8. I may be mistaken but as far as I understand it is not GRASS but something related to wxPython for python 3 in the platform in question. I am using openSUSE 15.1 and already spent a too much time trying in vain to solve this. For the time being I will use GRASS in command line or via QGIS.

/H.

No, I did not report this to the GRASS list. I probably tweaked too many things, many more that I can remember to make a useful account of what happened. But as I wrote I have reasons to believe the problem is related to the local wxPython implementation, not GRASS.
