Hello,
I am trying to create a dev environment for linux kernel development, and when following the guide, I need to compile busybox manually and use the output as initramfs, but I can’t even compile the busybox using make, and I got this error:
Your linker does not support --sort-section,alignment
Your linker does not support --sort-common
Static linking against glibc, can't use --gc-sections
Trying libraries: m resolv

/nix/store/81xsp348yfgmaan9r5055mcdjfw7a8wc-binutils-2.42/bin/ld: cannot find -lresolv: No such file or directory
I have the following packages in my dev environment:
{
inputs = {
fenix = {
url = "github:nix-community/fenix";
inputs.nixpkgs.follows = "nixpkgs";
};
flake-utils.url = "github:numtide/flake-utils";
nixpkgs.url = "nixpkgs/nixos-unstable";
};
outputs = { self, fenix, flake-utils, nixpkgs }:
flake-utils.lib.eachDefaultSystem (system:
let
pkgs = nixpkgs.legacyPackages.${system};
fenix' = fenix.packages.${system};
rust-pack = (fenix'.complete.withComponents [
"cargo"
"clippy"
"rust-src"
"rustc"
"rustfmt"
"rust-std"
"rust-docs"
"rust-analyzer"
]);
in {
devShell = with pkgs; mkShell ({
packages = [
rust-pack
rust-bindgen
openssl
pkg-config
# kernel
stdenv
git
gnumake
bc
flex
bison
elfutils
binutils
openssl
qemu_full
gcc
gdb
clang
clang-tools
lld
libllvm
];
hardeningDisable = linux.hardeningDisable ++ ["strictoverflow"];
LD_LIBRARY_PATH = "${glibc.static}/lib:${builtins.getEnv "LD_LIBRARY_PATH"}";
});
}
);
}
Why can’t the linker detect the m and resolv library? And how to fix this? Thanks!
