The ld-wrapper.sh script calls `readlink` in some circumstances. We need to ensure that this is the `readlink` from the `coreutils` package so that flag support is as expected. This is accomplished by explicitly setting PATH at the top of each shell script. Without doing this, the following happens with a trivial `main.c`: ``` nix-env -f "<nixpkgs>" -iA pkgs.clang $ clang main.c -L /nix/../nix/store/2ankvagznq062x1gifpxwkk7fp3xwy63-xnu-2422.115.4/Library -o a.out readlink: illegal option -- f usage: readlink [-n] [file ...] ``` The key element is the `..` in the path supplied to the linker via a `-L` flag. With this patch, the above invocation works correctly on darwin, whose native `/usr/bin/readlink` does not support the `-f` flag. The explicit path also ensures that the `grep` called by `cc-wrapper.sh` is the one from Nix. Fixes #6447
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 git://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-15.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-15.09
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
