mapnik fails to build with ubuntu/debian with scons: building terminated because of errors

[Jomy10]

I'm having the same error. I read that it could be something to do with c++17, as I can see in the build commands, the flag -std=c++14 is passed to the C compiler. I think changing to c++17 might fix this?

My Dockerfile is this:

adding CXX_STD=17 might resolve the issue.

If you are going to use a clone of https://github.com/mapnik/mapnik.git, I might suggest using CMake to build Mapnik. As far as I understand, it will be the recommended method (and potentially the only supported one) to build the upcoming 4.x.x releases.

May I suggest updating the build instructions for modern systems. They are very out of date.
