Can't build (macOS)

[genericptr]

Is my C++ compiler the wrong version maybe?

Hello @genericptr,

I think you need to use updated clang version to be able to compile C++20

[genericptr]

I don't use C++ much on macOS but I think you may need to add some additional flags to get c++ 20 support. It's also possible Apple hasn't implemented the full feature set.

There's the version I'm using which seems to be up to date.

Homebrew clang version 16.0.4
Target: arm64-apple-darwin22.6.0
Thread model: posix
InstalledDir: /opt/homebrew/opt/llvm@16/bin

[AmrDeveloper]

I will search about this issue and check if i can solved it by adding flag or other thing

[AmrDeveloper]

@genericptr Can you please add this line on amun_compiler.cpp file

#include <llvm/ADT/Optional.h>

[genericptr]

great that fixed that error. I still get errors but these are probably because I'm using LLVM 16. I think I can download a LLVM 15 version but not sure if the build system will use the correct one.

@genericptr Great, Yes i think getPointerElementType removed from llvm 16, it will work fine on llvm 15 and i will asap modify the code to work fine on llvm 16 and above
