Technically, this is a breaking change because something may depend on the presence of the SDK even without a compiler. I reviewers feel strongly about it, I can drop the backport. On the other hand, having the SDK in the dev shell creates a bad experience for users who expect |

Dropping the backport label at @emilazy’s recommendation since we’re half-way through the stable cycle, and this is a breaking change. Users who need a no-CC dev shell should either use unstable or use the following override on stable (24.11). mkShellNoCC = pkgs.mkShellNoCC.override {
stdenv = pkgs.stdenvNoCC.override { extraBuildInputs = [ ]; };
}; |
Darwin includes its SDK in `extraBuildInputs`, which isn’t needed in `stdenvNoCC` because it depends on a compiler. Including it greatly increases the size of the `stdenvNoCC` closure (by ~1 GiB). This wasn’t an issue in the past when darwin included CoreFoundation because CoreFoundation on its own is very small. Now that it includes the whole SDK and links some bintools, it pulls in 300~400 MiB for the SDK plus another ~445 MiB for LLVM. Fixes NixOS#371465
