constexpr function 'spz::times' cannot result in a constant expression

[TobyGilbert]

The 'times' overload constexpr Quat4f times(const Quat4f &a, const Quat4f &b) results in the following error on windows:

constexpr function 'spz::times' cannot result in a constant expression

This function appears to be unused, so removing it resolved this issue but this may be the reason why this error is not occurring on other platforms.

I do have a warning on Linux. Another fix could be to change constexpr to inline.

This was an error for me on linux w/ gcc 9.4. Changing constexpr to inline made the error go away for me as well.

I believe the root cause of this is that Quat4f normalized(const Quat4f& v); is not a constexpr function.

Met the same issue on Windows w/ VS2022. Changing the constexpr to inline would resolve the issue.
