the cross compilation functionality.
- I renamed some expected stdenv.mkDerivation parameter attributes so we can
keep this branch properly updated from trunk. We agreed with Nicolas Pierron
doing a massive renaming, so all current buildInputs become hostInputs (input
as build for the host machine, in autotools terminology) , and
then buildInputs would mean "input as for the build machine".
By now, the specific "input as for the build machine" is specified through
buildNativeInputs. We should fix this in the merge to trunk.
- I made the generic stdenv understand the buildNativeInputs, otherwise if
we start changing nixpkgs expressions so they distinguish the current
buildInputs into buildInputs and buildNativeInputs, we could break even more
nixpkgs for other platforms.
- I changed the default result of mkDerivation so it becomes the derivation for
to be run in the build machine. This allows, without any special rewriting,
"fetchurl" derivations to be always results for the build machine to use
them.
- The change above implies that, for anyone wanting to cross-compile, has to
build the hostDrv of the wanted derivation. For example, after this commit,
the usual test of "nix-build -A bison.hostDrv arm.nix" works. I described
the contents of this arm.nix in r18398.

It still does not work, but I think I already get glibc cross compiled.
Next: gcc and g++, and set some setup script hooks on stdenvCross.
It took quite enough hours for this commit.

My idea is to provide special stdenv expressions that will contain in the path
additional cross compilers. As most expressions for programs accept a stdenv parameter,
we could substitute this parameter with the special stdenv, which will have a
generic builder that attempts the usual "--target=..." and can additionally
have an env variable like "cross" with the target architecture set.
So, finally we could have additional expressions like this:
bashRealArm = makeOverridable (import ../shells/bash) {
inherit fetchurl bison;
stdenv = stdenvCross "armv5tel-unknown-linux-gnueabi";
};
Meanwhile it does not work - I still cannot get the cross-gcc to build.
I think it does not fill the previous expressions with a lot of noise, so I
think it may be a good path to follow.
I only touched some files of the current stdenv: gcc-4.3, kernel headers
2.6.28, glibc 2.9, ...
I tried to use the gcc-cross-wrapper, that may be very outdated. Maybe I will
update it, or update the gcc-wrapper expression to make it fit the cross tools,
but meanwhile I even cannot build gcc, so I have not tested the wrapper.
This new idea on cross compiling is not similar to that of the
nixpkgs/branches/cross-compilation, which mostly added bare new expressions for
anything to be cross compiled, if I understood it correctly.
I cared not to break anything of the usual stdenv in all this work.

This comes from:
svn diff ^/nixpkgs/trunk/@18255 ^/nixpkgs/branches/stdenv-updates/ > diff
patch -p0 < diff
and then adding into svn all files new from the patch.
trunk@18255 comes from the last time I updated stdenv-updates from trunk.

I thought I didn't change stdenv, but I did. This will go soon into the stdenv
branch then.

* Use patchelf 0.5 and use the --force-rpath flag. This removes the
need for setting LD_LIBRARY_PATH and so should fix bootstrapping
Nixpkgs on non-NixOS platforms.

instead of "gcc-4.3.3". This fixed the long-standing annoyance that
you can't distinguish the two in (say) nix-store -qR.
* On x86_64-linux, put $out/lib64 in the RPATH in addition to
$out/lib, because some packages (in particular GCC) put libraries in
$out/lib64 and ended up linking against the wrong library.
* Strip $out/lib64.
* Removed g77_42 because it's exactly the same as gfortran.
svn path=/nixpkgs/branches/stdenv-updates/; revision=14708
* Updated stdenv-linux:
- The bootstrap tools are no longer statically linked (except for
binaries in the Nixpkgs tree used to download and unpack the
bootstrap tools).
- x86_64 uses the same static binaries as i686. This makes the
Nixpkgs tree a bit smaller.
- Use the Linux 2.6.28 headers.

Instead of using a mishmash of statically linked and dietlibc
programs (which often have problems on various platforms), we just
use normal, dynamically linked binaries, and use some patchelf magic
to rewrite them so that they can find Glibc. Also include G++ and
Perl, since there are some builds in the bootstrap that need them.

bootstrap wasn't recycled in the final allPackages, causing an
additional glibc to be built for packages that explicitly depend on
glibc.
svn path=/nixpkgs/trunk/; revision=12200
* Some fetchurl-related refactoring. The `realCurl' attribute is
gone, `curl' is the real thing. To prevent an infinite recursion in
`fetchurl' (because it depends on curl and building curl needs
fetchurl), curl and its dependencies (openssl, zlib, perl) use
`fetchurlBoot', which is the fetchurl used by the previous bootstrap
phase (e.g. the statically linked version of curl for
stdenv-linux). So as a result you can use https:// urls almost
everywhere.
There's also some hackery to prevent a different curl from being
built in every stdenv-linux bootstrap phase (namely the
stdenv.fetchurl attribute which allows fetchurl to be overriden
everywhere).
