Bazel - unknown argument '-fno-canonical-system-headers'

Issue

I found the issue when I was following the tutorial on a new Macbook Pro: Introduction to Bazel: Building a C++ Project.

Use std::string_view to avoid string copy in C++17
Sep 16, 2018
Tl;dr
In some cases, the newly introduced std::string_view in C++17 is faster than std::string, because string_view only needs the pointer to the first element and the length of the string sequence, it omits string copy and provides an immutable-view of original data.

Copy constructor and emplace_back() in C++

Aug 8, 2018

A copy constructor of class T is a non-template constructor whose first parameter is T&‍, const T&‍, volatile T&‍, or const volatile T&‍, and either there are no other parameters, or the rest of the parameters all have default values.

from cppreference.com

Syntax

// Typical declaration of a copy constructor.
class_name ( const class_name & )
// Forcing a copy constructor to be generated by the compiler.
class_name ( const class_name & ) = default;
// Avoiding implicit generation of the copy constructor.
class_name ( const class_name & ) = delete;
