This is a known bug in gcc Concepts TS implementation. It is fixed by Andrew Sutton already on the C++20 Concepts branch. Basically the problem is that when you are using terse syntax for concepts in function arguments the concept of a return type is not verified 😜
This works:
#include <iostream>
#include <units/dimensions/velocity.h>
#include <units/dimensions/acceleration.h>
template<units::Velocity V, units::Time T>
units::Acceleration acc(V l, T t)
{
return l * t;
}
int main()
{
using namespace units::literals;
std::cout << acc(144.km / 1.h, 2.h).count();
}
