#31292 closed Bug (fixed)

Calling gdal_full_version() is broken on Python 3

Description

The GDAL _version_info() ctypes call uses a c_char_p type as first argument. In the Python-3 port (5330cd50cdb0674cd08cbfb40af9ac51267fbbec) the gdal_version() was updated to reflect that, but the gdal_full_version() function below was missed. It currently raises the following error:

ctypes.ArgumentError: argument 1: <class 'TypeError'>: wrong type

The solution is simply to call gdal's _version_info() with a bytes value too.
The PR ​https://github.com/django/django/pull/12467 fixes that.
