Clang settings ?

[Practical-UVM-Step-By-Step]

Hello:
on OSX Catalina:
is this clang-format off supposed to be a compiler ifdef? seeing some errors like below.
Basically a virgin checkout, cmake .. -G XCode and opened the generated project to build.

// clang-format off
#define TU(x)
x(Seconds)
x(Milliseconds)
x(Microseconds)
x(Nanoseconds)
x(Picoseconds)
x(Femtoseconds)
/// Scale unit for a time value.
ENUM_SIZED(TimeUnit, uint8_t, TU). // Error on Line 23 in Time.h : Constexpr variable 'values' must be initialized by a constant expression
#undef TU
// clang-format on

No, the comment is just to turn off auto-formatting, it doesn't affect the compiler in any way.

slang builds under Xcode 13, not sure if it will build with earlier versions. Unfortunately Apple ties Xcode releases to OS updates, so if you want to keep using Xcode you may be forced to upgrade to get a more modern compiler. Alternatively you can always install clang separately via homebrew or whatever and build that way.

Thanks!
