During configure I get:
Checking if compiler (clang++-10) supports -std=c++14 flag... no
C++ compiler does not support C++14 standard (-std=c++14), which is required. Please upgrade your compiler
I have seen that this issue has been reported already multiple times.
For instance here https://ircama.github.io/osm-carto-tutorials/tile-server-ubuntu/ I found a note that one should set the environment variables like
export CXX="clang++-10" && export CC="clang-10"
I also installed clang-12, as this seems the latest available for Ubuntu 20.04. I set
export CXX="clang++-12" && export CC="clang-12"
I's not working either. Very likely the reason for the issue is not the reported one.
What can be wrong here?
Btw., not sure whether this relates to that: Initially configure did not work at all because it reported that python >= 3.5 is required.
Although there had been installed also newer versions of python, /usr/bin/python did point to /usr/bin/python2 on my system. I changed that link accordingly and I did not receive this error any more.

When I ran into this error it turned out to be due to an error immediately above it, one of the dependencies needed to be updated. I can't remember which one, unfortunately, but I'd check the log file and see what happened right before this error came up.
Because my initial problem with mapnik could be reduced to a wrong usage I don't need to compile it from the sources any more. However, this issue seems strange nonetheless....
Because I had troubles that mapnik-render (version 3.0.23) does not work for whatever reason I tried to build it from source as described here: https://github.com/mapnik/mapnik/wiki/UbuntuInstallation
