configuration option. For instance, to override GCC globally for
all of Nixpkgs, you can put the following in ~/.nixpkgs/config.nix:
{
packageOverrides = pkgs: {
gcc = pkgs.gcc41;
}
}
This should make a lot of configuration support in Nixpkgs
unnecessary, like selectVersion and many little-used configuration
options.
It also provides a somewhat convenient place to put custom,
private additions to Nixpkgs, e.g.
{
packageOverrides = pkgs: {
myHello = pkgs.stdenv.mkDerivation {
name = "my-hello-0.1";
buildCommand = ...;
};
};
};
Note that this requires Nix >= 0.12pre12726.
* Removed the `myPackages' option `packageOverrides' obsoletes it.
