Hello everyone,
I’m new to nix and I need to build the linux kernel using a custom config. Not a defconfig. Just use a specific config file to build. I’m on nixos 18.09 and looking at the source of buildLinux there is only a way to specifiy a defconfig file or extraConfig. How can I use a specific config file to build a linux kernel?
was going to point you at Linux kernel - NixOS Wiki but I realize there is no example for a .config yet. Bottomline is you want to use linuxManualConfig. From my overlay:
linux_mptcp_trunk = (prev.linuxManualConfig {
inherit (prev) stdenv;
inherit (linux_mptcp_trunk_raw) src version modDirVersion;
configfile = ./kernels/mptcp_trunk_netlink.config;
# we need this to true else the kernel can't parse the config and
# detect if modules are in used
allowImportFromDerivation = true;
}).overrideAttrs (oa: {
shellHook = ''
touch .scmversion
echo "hello boss"
'';
});
