Question

I was Following This Tutorial Video to Code with C++, But when I try build Using Scon command(5:27 of this video), i get This Long Error Message(I also tried mingw)

Thanks and I Really need your Help. I hope in future there be an Easier ways to use C++ in godot.

Looking up your error you have an older version of c++. You should update your compiler.
