The following simple program compiles with g++ (12.1.0) and fails with clang (14.0.6) with a very long and not so descriptive error

#include <ranges>
#include <vector>
int main() {
  std::vector<int> v{1, 2, 3};
  auto fview = std::ranges::views::transform(v, [](auto p) { return p; });
  return 0;
}

The error with clang is error: no matching function for call to '__begin' and it goes on for about 183 lines to paste here. What am I getting wrong?

You need to specify `-stdlib=libc++` to use `libc++` instead of `libstdc++`. – 康桓瑋 Jul 15 '22 at 01:28
that's unfortunately not possible since `libc++` misses even more c++20 headers like ``. – Reimundo Heluani Jul 15 '22 at 08:49
libc++ definitely implements ``. – 康桓瑋 Jul 15 '22 at 08:56
