symbol lookup error: undefined symbol: __atomic_load

Question

I am defining an atomic variable of a struct type and the code compiles fine, but when I call the load() method on the atomic variable, I get a symbol lookup error. What am I doing wrong?

struct Foo
{
  double baz;
  double bar;
};

std::atomic<Foo> atomic_foo {Foo {1.0, 2.0}};

auto foo {atomic_foo.load()};  // <-- symbol lookup error: undefined symbol: __atomic_load
