I made the stdenvCross adapter simpler, according to Nicolas Pierron comments,
and I commented it a bit.
There are still jobs to do. At least:
- Plan for the general renaming from buildInputs to hostInputs
- We should not break merges from trunk.
- Make the generic stdenv understand about host/buildInputs, at least for
native builds, because it is used in the always-native building of
stdenvLinux. This should allow us to remove all duplications of "*NoCross" in
nixpkgs.

needing to keep a new tree of expressions apart for the expressions to get
cross-compiled.
I changed the whole way of using cross compilation with nixpkgs, which before
was done through a simple adapter.
Now the adapter became complex, and I've tried to avoid the most obvious
recursivities. For example, the fetchurl expression should
never be cross-compiled, as the gmp, mpfr, and some others, like
some ncurses, perl, ... I made overrided copies of those necessary as
perlNoCross, ncursesNoCross, as stdenvNoCross, keeping in mind that
the stdenv (capable of cross compilation) is built upon stdenvNoCross using
an adapter.
So, to cross compile, instead of building using "nixpkgs/default.nix",
you should build with your
own "myarchiteture.nix", which should have contents like these, for example:
import /etc/nixos/nixpkgs/default.nix
{
crossSystem = {
config = "armv5tel-unknown-linux-gnueabi";
bigEndian = false;
arch = "arm";
float = "soft";
};
}
svn path=/nixpkgs/branches/stdenv-updates/; revision=18398
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.
svn path=/nixpkgs/branches/stdenv-updates/; revision=18351
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.

Nixpkgs tree a bit smaller.

* 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).

The function for use in setup hooks. The syntax is very simple:
add_to_var varName needDir addDir prefix
If the directory $prefix$needDir exists, directory $prefix$addDir is added to
variable named varName (using PATH_DELIMITER as delimiter). If addDir is "", it
defaults to needDir (this is a most common case).

This has a major advantage: you can write hooks directly in Nix
expressions. For instance, rather than write a builder like this:
source $stdenv/setup
postInstall=postInstall
postInstall() {
ln -sf gzip $out/bin/gunzip
ln -sf gzip $out/bin/zcat
}
genericBuild
(the gzip builder), you can just add this attribute to the
derivation:
postInstall = "ln -sf gzip $out/bin/gunzip; ln -sf gzip $out/bin/zcat";
and so a separate build script becomes unnecessary. This should
allow us to get rid of most builders in Nixpkgs.
* Allow configure and make arguments to contain whitespace.
Previously, you could say, for instance
configureFlags="CFLAGS=-O0"
but not
configureFlags="CFLAGS=-O0 -g"
since the `-g' would be interpreted as a separate argument to
configure. Now you can say
configureFlagsArray=("CFLAGS=-O0 -g")
or similarly
configureFlagsArray=("CFLAGS=-O0 -g" "LDFLAGS=-L/foo -L/bar")
which does the right thing. Idem for makeFlags, installFlags,
checkFlags and distFlags.
Unfortunately you can't pass arrays to Bash through the environment,
so you can't put the array above in a Nix expression, e.g.,
configureFlagsArray = ["CFLAGS=-O0 -g"];
since it would just be flattened to a since string. However, you
can use the inline hooks described above:
preConfigure = "configureFlagsArray=(\"CFLAGS=-O0 -g\")";

* The statically linked bootstrap tools are now automatically

These are checked out on nix.cs.uu.nl under http://.../dist/tarballs.
* The statically linked libraries all use dietlibc now (except
patchelf and glibc), so they are much smaller. This is especially
nice for the tools in the Nixpkgs tree, since it makes Nixpkgs
tarballs smaller.
* Use Binutils 2.17 and GCC 4.1.1 for the bootstrap.
* The stdenv is now based on Glibc 2.5. I hope it works ;-)
