The solution is actually in your error message, though I admit it's a little buried:

2 | use core::ops::{Add, AddAssign, BitAnd, BitOr, BitXor, BitXorAssign, Not};
| ^^^^ can't find crate
|
= note: the aarch64-apple-darwin target may not be installed
= help: consider downloading the target with rustup target add aarch64-apple-darwin

Try running rustup target add aarch64-apple-darwin, the project is configured to build universal binaries so you need toolchains for ARM and x86_64.

It built ok up until this version, so this is new. I will try this, thanks for the information. Something that will need to be added to the MacOS howto

% rustup target add aarch64-apple-darwin % rustup update % cargo update Did not fix this issue

Similar issue on MacBook Air, Apple M2, MacOS Sonoma 14.2.1. Builds are now failing that used to work. First error is

error[E0463]: can't find crate for `core`
  |
  = note: the `x86_64-apple-darwin` target may not be installed
  = help: consider downloading the target with `rustup target add x86_64-apple-darwin`

but running similar rustup/cargo commands as previous comment (with x86_64 instead of aarch64) has the same outcome and builds fail.

The existing make files builds x86_64 and aarch64 (copies over the top of the binary) I have an updated Makefile here that selects the correct build and Displays the System Architecture and Compiler at the start. The is still and @rpath issue. I will close this issue and start a new one with new errors. https://github.com/snakebyte69/fab-agon-emulator
