I am seeing the identical error.

[Adu-3]

Same issue

[perstarkse]

Specifying to use gcc13 in nativeBuildInputs works. Looking into it it seems that there is a somewhat stale PR in the nanosvg repo that silences the warning causing the error memononen/nanosvg#256 . This is not my domain and Im unsure on how to best approach this situation.

[paparodeo]

replacing the vendored nanosvg with the one from nixpkgs will fix the build.

There's an issue here that's somewhat relevant, I had to pin my nixpkgs to the commit specified within that issue previous to the issue occurring, and both my issue with llvm and this worked, so potentially a connection to a version bump in gcc?

#368672

anywho configuring my nixpkgs input in my flake.nix as per below has worked around the issue for me,

 nixpkgs.url = "github:nixos/nixpkgs/585f76290ed66a3fdc5aae0933b73f9fd3dca7e3";
