error C2397: conversion from 'int' to 'uint64_t' requires a narrowing conversion

Where does that happen? What MSVC version?

Where does that happen?
I am trying to build openal-soft from source code. (https://github.com/kcat/openal-soft/archive/refs/tags/1.24.0.tar.gz)

What MSVC version?
Microsoft Visual Studio Community 2017
Version 15.9.57
VisualStudio.15.Release/15.9.57+34031.82

OS is Windows 10

These errors occur during the build: (warnings omitted)

Hope this helps.

Looks like the compiler doesn't like "narrowing" a constexpr value, when the value needs to be known at compile time and it must know it fits in the new type. Are you able to upgrade MSVC? It seems to work with VS 17 (MSVC 19), if you're able to upgrade to at least that.
