My earlier change mistakenly expected `toString false` to produce '0' instead of the empty string, leading to unexpected config changes. Intended to address issue mentioned here and in following discussion: https://github.com/NixOS/nixpkgs/pull/53972#issuecomment-459981602 Sorry, folks! (special-case handling of bools here makes this "cleanup" a bit less of an obvious win but hopefully still preferable overall :)) ----------- makeFlags in resulting derivation, according to this one-liner: $ nix show-derivation -f . openblas|jq ".[].env.makeFlags" before: "BINARY=64 CC=cc CROSS= DYNAMIC_ARCH=1 FC=gfortran HOSTCC=cc INTERFACE64=1 NO_BINARY_MODE= NO_STATIC=1 NUM_THREADS=64 PREFIX=/1rz4g4znpzjwh1xymhjpm42vipw92pr73vdgl6xs1hycac8kf2n9 TARGET=ATHLON USE_OPENMP=1" after: "BINARY=64 CC=cc CROSS=0 DYNAMIC_ARCH=1 FC=gfortran HOSTCC=cc INTERFACE64=1 NO_BINARY_MODE=0 NO_STATIC=1 NUM_THREADS=64 PREFIX=/1rz4g4znpzjwh1xymhjpm42vipw92pr73vdgl6xs1hycac8kf2n9 TARGET=ATHLON USE_OPENMP=1" Without knowing how `placeholder` works, it seems interesting if entirely unrelated that the `PREFIX` is same for both! :). TIL.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.09
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
