Hello!
Well, your file needs stdenv,fetchurl,openssl from nixpkgs. So, first, your
expression should include nixpkgs for those:
Keeping your rhash.nix:
nix-env -E 'let pkgs = import /etc/nixos/nixpkgs; in { rhash = import
./rhash.nix {
inherit (pkgs) stdenv fetchurl openssl}; }' -i rhash
I don't know if it does work. But do you get the idea?
Regards,
Lluís.

Excerpts from Иван Левашев's message of Sun Dec 04 07:43:14 +0100 2011: I'm running in circles. I can't install a self-written derivation that I haven't written into all-packages.nix. Manual only has samples where a package is present in all-packages.nix. I don't want to touch this file yet. That's the way to go: use packageOverrides: https://nixos.org/wiki/Howto_keep_multiple_packages_up_to_date_at_once Keeping changes to nixpkgs is fine as well - for a limited time. If you want to keep patches longer you have to create your own branches (using SVN asking for access) - or by using git/mercurial/... mirrors. I maintain git mirrors for nixos/nixpkgs. Thus forking and keeping local changes is cheap. Contact me on irc (MarcWeber) if you want more details about the git way and write again if the wiki page above does not show what you're looking for.

Ivan,
One trick that I use is that your $HOME/.nix-defexpr will be scanned for
.nix files. It may be possible to put your rhash expression file there
directly, but the setup I use is to have a $HOME/my_nixexprs directory
with a subdirectory for each local package+nix expression file I want, and
a $HOME/my_nixexprs/default.nix that acts similarly to all-packages.nix
and is invoked by a local.nix file in my $HOME/.nix-defexpr.
For example:
$ cat $HOME/.nix-defexpr/local/nix:
{}:
let
toplevel = import /etc/nixos/nixpkgs/pkgs/top-level/all-packages.nix{};
empkgs = toplevel.emacsPackages { emacs = toplevel.emacs; };
evempkgs = empkgs { self = toplevel; };
haskellMode = evempkgs.haskellMode;
getEnv = x: if builtins ? getEnv then builtins.getEnv x else ;
homeDir = getEnv HOME;
myNix = homeDir + /my_nixexprs;
in
import myNix { inherit toplevel; }
$
Note here that I have a couple of local definitions for various
environments or settings from all-packages.nix that I may need in my local
expressions. You may need to update this periodically and as appropriate
for your needs.
$ cat $HOME/my_nixexprs/default.nix
{ toplevel }:
let
empkgs = toplevel.emacsPackages { emacs = toplevel.emacs; };
in
rec {
haskellmodedarcs = import ./haskell-mode-darcs {
inherit (toplevel) stdenv fetchurl fetchdarcs emacs;
inherit empkgs;
};
smg = import ./smg { inherit (toplevel) fetchurl python
buildPythonPackage; };
pylibpcap = import ./pylibpcap { inherit (toplevel) fetchurl python
stdenv libpcap; };
# Done. Requires autoconf/automake though which causes lots of needed
updates.
# Better to just use configureFlags for overrides?
lnav = import ./lnav {
inherit (toplevel) zlib stdenv fetchurl ncurses;
inherit (toplevel) pcre readline sqlite binutils;
autoconf = toplevel.autoconf;
automake = toplevel.automake110x;
};
trowser = import ./trowser {
inherit (toplevel) stdenv fetchurl tcl tk;
};
}
$
The above default.nix functions as my local all-packages.nix and I add or
remove packages (local subdirectories) as they are ready or retired. This
default.nix (plus my local.nix) provide all the tweaking so that the nix
expression for the local packages is not aware that is it not part of the
/etc/nixos/nixpkgs/ tree.
$ cat $HOME/my_nixexprs/pylibpcap/default.nix
{stdenv, fetchurl, python, libpcap}:
let
version=0.6.2;
in
stdenv.mkDerivation rec {
name = pylibpcap- + version;
src = fetchurl {
url = mirror://sourceforge/pylibpcap/${name}.tar.gz;
sha256 =
0cdb507eaf27e7d6f4e3ee74a5986e14728fd8161785350d201a12198c19fcc6;
};
buildInputs = [python libpcap];
buildPhase = python ./setup.py build;
installPhase = ''
python ./setup.py install --prefix=$out || exit 1
'';
meta = {
description = Python module for the libpcap packet capture library;
homepage = http://pylibpcap.sourceforge.net/;
};
}
$
Hope this helps and that it's not too far from normal Nix practices.

[Nix-dev] (newbie) nix-env custom package installation
Hello!
I'm running in circles. I can't install a self-written derivation that I
haven't written into all-packages.nix. Manual only has samples where a
package is present in all-packages.nix. I don't want to touch this file yet.
So I have written rhash.nix:
{stdenv, fetchurl, openssl ? null}:
let
version = 1.2.8;
in
stdenv.mkDerivation {
name = rhash-${version};
inherit openssl;
makeFlags = if openssl != null then ADDCFLAGS=\-DUSE_OPENSSL
-DOPENSSL_RUNTIME -rdynamic\ ADDLDFLAGS=\-ldl\ else ;
src = fetchurl {
url =
mirror://sourceforge/rhash/${version}/rhash-${version}-src.tar.gz;
md5 = 6b9db38cc322caa5cd0151abdc92a2b5;
};
buildinputs = if openssl != null then [openssl] else [];
meta = {
homepage = http://rhash.anz.ru/?l=en;;
description = RHash (Recursive Hasher) is a console utility for
computing and verifying hash sums of files;
};
}
Now I'm trying to guess how to install it.

{}) ;}' -i rhash --dry-run
(dry run; not doing anything)
error: attempt to call something which is neither a function nor a

I believe it to be indeed possible, but I've ran out of ideas. IIUC I
must construct something similar to what is defined in all-packages.nix,
but all-packages is too long, I can't easily overlook it.
If that means something, I have NixOS installed inside VMWare Server
(it's free, BTW).
Best regards,
Ivan Levashew

I'm running in circles. I can't install a self-written derivation that I
haven't written into all-packages.nix. Manual only has samples where a

most simple cases are handled by my script
/etc/nixos/nixpkgs/maintainers/scripts/nix-call-package
So I have written rhash.nix:
{stdenv, fetchurl, openssl ? null}:
Yup, arguments seem to be auto-findable

Currently free of charge, you mean? Yes, I guess most people here knows.
