[Nix-dev] cannot build coreutils

[Ben Franksen]

Hi All

I am trying to use an older version of gcc (4.4) to compile a new cross-gcc 
for RTEMS-4.9, since building with a current gcc fails. I am using the 
nixpkgs from the stable nixos-13.10 branch.

I have this

    binutils_powerpc_rtems49 = callPackage rtems/4.9/binutils {
      stdenv = stdenvAdapters.overrideGCC stdenv gcc44;
      targetArch = "powerpc";
    };

in packageOverrides inside config.nix. When I try to build, I get an error 
in the configure phase for coreutils:

 > nix-env -i binutils-powerpc-rtems4.9

I think something is wrong here. Why does configure think it is running as 
root? I am using the standard multi-user setup with nixbld0..nixbld9 as 
build users.
