I hope I resolved the conflicts well (gmp and gccCross)

Lluís Batlle i Rossell 8c2af71a0f Fixing the gcc-cross-wrapper (wanting to make it work with uclibc, I had
broken it for glibc).
Now I tested that it works for both.

Lluís Batlle i Rossell fb6adb13ac Updating busybox. I left only a single busybox in its directory. The others, coming from the old
cross-building nixpkgs implementation, were not referenced anywhere.

This new busybox builds natively, and also cross-builds with uclibc.

I updated the uclibc config with a busybox defconfig requirement (something about RPC).

I made the gcc-cross-wrapper properly set the dynamic loader to programs.

After this, 'qemu-arm' can run the dynamically linked busybox cross built for armv5tel--linux-gnueabi.

Lluís Batlle i Rossell c6b526495b Improving the crossStripping. A cross-glibc gets broken if stripped by the
native strip. So we now distinguish dontStrip and dontCrossStrip. I updated
the expressions for glibc-2.9 and glibc-2.11 accordingly.
I could get rid of the cross-glibc depending on the cross-gcc-stage-static.

Enabling nls in the final cross-gcc.

I still have problems on wint_t/wchar_t not working on cross build. Gettext
does not build.

Lluís Batlle i Rossell 45886e474d On native builds:
- Disabling guile test, because one fails. I commented on that in the source.
On cross builds:
- Adding stripping
- Updating the glibc-2.11 expression to match the parameters of glibc-2.9,
  which I was updating more.
- Renaming from selfNativeBuildInput to selfBuildNativeInput, so this matches
  better the pattern buildNativeInputs.

Lluís Batlle i Rossell 585ba8c27f Big fixes in the cross build:
- Before this changes, cflags and ldflags for the native and the cross compiler
  got mixed. Not all the gcc-wrapper/gcc-cross-wrapper variables are
  independant now, but enough, I think.
- Fixed the generic stdenv expression, which did a big mess on buildInputs and
  buildNativeInputs. Now it distinguishes when there is a stdenvCross or not.
  Maybe we should have a single stdenv and forget about the stdenvCross
  adapter - this could end in a stdenv a bit complex, but simpler than the
  generic stdenv + adapter.
- Added basic support in pkgconfig for cross-builds: a single PKG_CONFIG_PATH
  now works for both the cross and the native compilers, but I think this
  should work well for most cases I can think of.
- I tried to fix the guile expression to cross-biuld; guile is built, but not
  its manual, so the derivation still fails. Guile requires patching to
  cross-build, as far as I understnad.
- Made the glibcCross build to be done through the usage of a
  gcc-cross-wrapper over the gcc-cross-stage-static, instead of using it
  directly.
- Trying to make physfs (a neverball dependency) cross build.
- Updated the gcc expression to support building a cross compiler without getting
  derivation variables mixed with those of the stdenvCross.

Lluís Batlle i Rossell a263cb814e Fixed some details on cross compilation. Among others:
- Stating better the guile dependencies (native/host) for guile to build
- Fixing cross-linking, through --rpath-link (ld(1) explains well about it
- Made gcc call the linker and the assembler through the gcc wrapper instead of
  directly. I thought this was the source of missing -rpath's, but the source
  of the problem ended up being the lack of --rpath-link. But I think the
  native gcc calls the wrapped ld and as, so let's do the same cross
  compiling.
- Removed the binutilsCross from the glibc expressions. Now they are built
  using the gcc-cross-wrapper, and they were built with the direct gcc and
  binutils before this change.
- I think patchelf and strip don't break the cross-compiled binaries, so I
  reallow them on cross compilation.
- I disable the checkPhase on cross compilation. This made gmp and libtool
  fail when cross compiled, iirc.

Lluís Batlle i Rossell a5fee3325a Fixing some things on the gcc-cross-wrapper (libc was not properly added to the
linking path), and with this achieved bash being cross-compilable.
I fixed the few expressions involved in bash building, so they have well stated
native and non-native inputs.

I also tried to cross-build guile, and with this I found a problem in the
actual cross-gcc: it calls the binutils ld, instead of the ld wrapper. This
way, the programs/shared_libraries don't get the proper -rpath.

Lluís Batlle i Rossell 6f3630e128 Attention, people who care on the builders for native builds. In the stdenv
derivation, the "buildInputs" in every stdenv mkDerivation don't map now
directly to the environment
variable "buildInputs" in the builder, but "buildNativeInputs". So, the inputs
build by the native compiler.
When cross compiling, they will map to the environment variable "buildInputs"
(yes, now the same name), which means does to be built with the cross compiler.

I think I improved the naming of variables a bit. There was a big mess,
specially in the stdenv adapter for cross building, and also in the default
builder script.

I also tried to add proper manager of propagatedInputBuilds, these being
propagated considering the host or build origin of that input build (so, at the
end, being those propagatedInputBuilds being propagated properly to the native
or the cross compiler.

Lluís Batlle i Rossell 3c4edd6bfa Fixing the gcc cross wrapper (removing some /usr/) so it gives proper linking.
svn path=/nixpkgs/branches/stdenv-updates/; revision=18361

Lluís Batlle i Rossell 2aba922d30 My first attempt at getting cross compilers in nixpkgs.
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.

Eelco Dolstra baec8f5b38 * stdenv.mkDerivation now takes an optional attribute "meta" that
contains arbitrary information about a package, like this:

  meta = {
    homepage = "http://gcc.gnu.org/";
    license = "GPL/LGPL";
    description = "GNU Compiler Collection, 4.0.x";
  };

  The "meta" attribute is not passed to the actual derivation
  operation, so it's not a dependency --- changes to "meta" attributes
  don't trigger a recompilation.

  Now we have to standardise some useful attributes ;-)

Armijn Hemel bdf35869f6 make sure we can find things like mips-linux-ar, mips-linux-strip, and so on.
Even though you could just inherit binutils it is conceptually cleaner (I
think) to make these tools available here.
