macOS nix-build: "make[1]: *** [Makefile:687: ../rust_src/crates/emacs/src/definitions.rs] Killed: 9"

[Atemu]

Describe the bug A clear and concise description of what the bug is.

When building emacs-ng on macOS with Web~~reader~~render, something gets killed with signal 9 during the build. I don't think this is an OOM since I've never seen something get reaped on OSX (it does very aggressive swapping).

Getting killed with -9 can sometimes mean that macOS doesn't allow you to be executed because you're lacking an apple-blessed signature or whatever; that might be a lead.

To Reproduce Steps to reproduce the behavior. What were the options you passed to configure?

Webrender feature can't build on macOS currently.

Also, I have no idea how to build emacsNg(without webrender) with Nix on darwin. (Maybe the current problem was from the older version of darwin-SDK)

I see, having the build fail because of a process being killed seemed unusual though.

The current non-webrender master gets quite far actually, only fails to link in the end.

You can use nix flake here https://github.com/declantsien/emacs-webrender/actions/runs/3835526145 to build webrender on macOS.
