Do we have support for C++20 ranges library in the newly released GCC 9?
I copied the example code below for ranges library from:
https://en.cppreference.com/w/cpp/ranges
#include <vector>
#include <ranges>
#include <iostream>
int main()
std::vector<int> ints0,1,2,3,4,5;
auto even = [](int i) return 0 == i % 2; ;
auto square = [](int i) return i * i; ;
for (int i : ints
But when compiled with g++ 9.1 (Ubuntu 18.04 LTS (Bionic Beaver)), it complains that <ranges> cannot be found:
$ g++ -std=c++2a cpp2a.cpp
cpp2a.cpp:2:10: fatal error: ranges: No such file or directory
2 | #include <ranges>
| ^~~~~~~~
compilation terminated.
Am I missing something?
And will the ranges library arrive at some point of time with the GCC 9 series?

No.
And will the ranges library arrive at some point of time with the gcc-9 series?
It's possible but seems unlikely.
Ranges is an enormous library. It's still 2019, the official C++20 standard still won't even be shipped for another year and a half. It'll take a while for it to get implemented in the major standard library implementations. We'll just have to wait.
If you want to start using Ranges, you can use Range-v3 (specifically the v1.0-beta branch) or you can find an implementation of C++20 Ranges at cmcstl2 (this is Casey Mysterious Carter's implementation).
You can also periodically check cppreference's compiler/library tracking page (which unsurprisingly currently shows no libraries having implemented the One Ranges proposal, but nevertheless does show quite a few C++20 features as having been implemented by the various library vendors).
