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.

on the native and cross platforms.
I thought I already did that today in a previous commit, but I did all wrong.
svn path=/nixpkgs/trunk/; revision=20280
I introduce the new nixpkgs parameter "platform", defaulting to "pc",
which was before defined as an attribute of nixpkgs.
I made the crossSystem nixpkgs attribute set parameter contain its own 'platform'.
This allows cross-building a kernel for a given crossSystem.platform in a non-PC
platform.
The actual native platform can be taken from stdenv.platform, and this way we also
avoid the constant passing of 'platform' to packages for platform-dependant builds
(kernel, initrd, ...).
I will update nixos accordingly to these changes, for non-PC platforms to work.
I think we are gaining on flexibility and clearness. I could cross build succesfully
an ultrasparc kernel and a mipsel kernel on PC. But since this change, I should be able
to do this also in non-PC.
Before this change, there was no possibility of distinguishing the "target platform" or
the "native build platform" when cross building, being the single "platform" attribute
always interpreted as target platform.
The platform is a quite relevant attribute set, as it determines the linuxHeaders used
(in the case, by now the only one supported, of linux targets).
The platform attributes are quite linux centric still. Let's hope for more generality to come.

Updating the cross-build expressions, adding some flexibility.
Updated the linux headers used cross building, as 2.6.28 had bugs on endianness in
sparc64.
There were, as usual some bugs in gcc. Maybe not many make a cross compiler to
ultrasparc.
For the record, I could build an ultrasparc kernel with this base nix:
import /etc/nixos/nixpkgs/default.nix # The root nixpkgs default.nix
{
crossSystem = {
config = "sparc64-unknown-linux";
bigEndian = true;
arch = "sparc64";
float = "soft";
withTLS = true;
cpu = "ultrasparc";
};
config = pkgs: {
packageOverrides = pkgs : {
platform = {
name = "sparc64";
kernelHeadersBaseConfig = "sparc64_defconfig";
kernelBaseConfig = "sparc64_defconfig";
kernelArch = "sparc";
kernelAutoModules = false;
kernelTarget = "zImage";
uboot = null;
};
};
};
}
Although it did not boot directly in qemu-system-sparc64:
[sparc64] Kernel already loaded
Unhandled Exception 0x0000000000000020

It seems that there is no make target named 'vmlinuz' that makes the file 'vmlinuz'.
So we need different variables for the make target and the kernel file. Unless we
some day stop using the file 'vmlinuz' in pc, and use bzImage.

I still have not added anything in the kernels about cross compilation.
I moved the platform definitions out of all-packages.
I have not written good platform definitions for the sheevaplug - only for the
PC.
Only the linux-2.6.32 expression uses the platforms kernelConfig.
The linux-2.6.31 was broken, and I left it broken.

* Move kernel patches out of all-packages.nix to
os-specific/linux/kernel/patches.nix.
* Make the kernel config available under $out/config (it's also in
$out/lib/modules/$version/build/.config, but that's kind of hard to
find).

`generate-config.pl' runs `make config' to generate a Linux kernel
configuration file. For each question (i.e. kernel configuration
option), unless an override is provided, it answers "m" if possible,
and otherwise uses the default answer (as determined by the default
config for the architecture). This is safer than allmodconfig,
which answers "y" everywhere it can't answer "m" and thus ends up
enabling a lot of experimental or debug options. (For this reason,
a configuration generated by allmodconfig must be carefully checked
with every new release to ensure that nothing dangerous is enabled.
The default config should be safer wrt new kernel releases.)
Overrides are specified in the `config' argument to generic.nix,
which is a string that contains lines such as `EXT2_FS_POSIX_ACL y'.
The script warns about ignored options, and aborts if `make config'
selects an answer inconsistent with the one in `config'. This
allows us to be sure that `make config' doesn't silently override
our configuration values (e.g., depending on other options, it will
set FB_TILEBLITTING to "y" even if we want it to be "n").

I think directory renaming breaks the usual merges... because it leaves the

- 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.

`selectVersion ./foo "bar"' instead of `import ./foo/bar.nix'.
* Replaced `with args' with formal function arguments in several
packages.
* Renamed several files to `default.nix'. As a general rule, version
numbers should only be included in the filename when there is a
reason to keep multiple versions of a package in Nixpkgs.
Otherwise, it just makes it harder to update the package.

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.
