Public bug reported:
Even though libicu66 "(>= 66.1~rc-1~)" is listed as a dependency for
python3-mapnik, there still seem to be some stale references to the
previous libicu65 in the python bindings library:
This is simple to reproduce by just trying to import mapnik:
# python3 -c "import mapnik"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib/python3/dist-packages/mapnik/__init__.py", line 74, in <module>
from ._mapnik import *
ImportError:
/usr/lib/python3/dist-packages/mapnik/_mapnik.cpython-38-x86_64-linux-gnu.so:
undefined symbol: _ZN6icu_6513UnicodeStringC1ERKS0_
The undefined symbol unmangled by c++filt is:
icu_65::UnicodeString::UnicodeString(icu_65::UnicodeString const&)
