Big closure size

[ck3d]

The closure size of nixd is round about 550Mb on latest nixpkgs.

I would be great if the runtime dependency to llvm-dev and nix-dev can be removed.

AFAIK, we do not rely on llvm-dev & nix-dev as runtime dependency, only llvm.out & nix.out.

LLVM closure size is much larger than many other repositories (e.g. Debian), it's only about 30~40M if properly packaged¹. You may refer to NixOS/nixpkgs#230616 and these llvm static libraries contributed most closure size (which is definitely unnecessary at runtime).

Footnotes

1. For example, on Debian (amd64) https://packages.debian.org/bookworm/llvm-14 it is only 48,353kb (47.2M) after installation. ↩

You are right, the llvm itself is the main problem.

My mentioned packaged llvm-dev and nix-dev are only a problem on darwin, the dependencies are:

/nix/store/qlml6qifkgs47s3gb714lcq4vh27qpic-libcxxabi-16.0.6
/nix/store/6zn9dj3sdncl5qafw52p5zx7zszxjpjm-libcxx-16.0.6

On linux, the package dependency shows following:

The root cause is the big llvm package, which needs to be fixed in nixpkgs. Therefor I close this issue.
Sorry for the noise.
