Comment (by martinl):

 `g.extension` changed in r73793 in order to support Python3. Would be
 better to create for new issues separted tickets. This ticket seems to be
 to generic. I would suggest to close it since originally reported issue
 has been solved and remaining issue (Python 3.7) is tracked by a new issue
 #3704. I took liberty to close the ticket. Feel free to re-open if needed.

 I had updated some and it also fails with those.

 To me it looks like a bug in g.extension itself:

 
https://trac.osgeo.org/grass/browser/grass/trunk/scripts/g.extension/g.extension.py#L1042

 When I delete these lines
 {{{
 #if '\0' in data:
 #continue  # ignore binary files
 }}}

 then g.extension works fine.

 I think most of the addons since they are mostly written for Python >= 2.6
 We need to port the addons to python3

 PS
 I think the Python3 support will required major release also to use the
 updated addons

 Hi, do you have any directions on how to test and debug `pygrass` build
 against `python3`? Which version/branch of `ctypegen`? Is anyone from the

 Yeah, but the beauty of open source development is that someone else can
 take over:

 If GRASS relies on ctypesgen, we have a problem, because the project is
 likely dead. The latest commit was 3 years ago, and the maintainer does
 not seems interested anymore (see
 https://github.com/davidjamesca/ctypesgen/issues/52).

Changes (by zarch):

 * keywords:  python python3 temporal => python python3 ctypes


Comment:

 Just remove the keyword: temporal and add ctypes, since the issue is due
 to ctypes and affect all the library based on them: temporal, pygrass.

 Various pygrass modules fail to import in Python 3.6.

 Python version:
 {{{
 Python 3.6.3 (default, Oct  3 2017, 21:45:48)
 [GCC 7.2.0] on linux
 }}}

 For example:
 {{{
 import grass.pygrass.gis
 Traceback (most recent call last):
   File "", line 1, in 
   File "/usr/lib/grass72/etc/python/grass/pygrass/gis/__init__.py", line
 14, in 
 libgis.G_gisinit('')
   File "/usr/lib/grass72/etc/python/grass/lib/gis.py", line 3489, in
 G_gisinit
 return (G__gisinit (GIS_H_VERSION, pgm))
 ctypes.ArgumentError: argument 1: : wrong type
 }}}

 This issue prevents pygrass and the temporal framework to work with
 python3:

 {{{
 >>> import grass.temporal as tgis
 Traceback (most recent call last):
   File "", line 1, in 
   File "/usr/lib/grass72/etc/python/grass/temporal/__init__.py", line 3,

 line 28, in

   File "/usr/lib/grass72/etc/python/grass/lib/gis.py", line 3489, in
 G_gisinit
 return (G__gisinit (GIS_H_VERSION, pgm))
