> What you’re meant to do is override the stdenv if you want it to use clang: pkgs.mkShell.override { stdenv = pkgs.clang19Stdenv; } { packages = [pkgs.cmake # ... whatever else, but NOT C compilers though!]; } (or inherit (pkgs.llvmPackages\_19) stdenv;, if you prefer) and instead of the deprecated devShell.\<system\>, use devShells.\<system\>.default.
