This solves the problem of the change of name in ld.so between
glibc 2.13 and 2.17 (at least for armhf). Some comments about it in
https://github.com/NixOS/nixpkgs/issues/234#issuecomment-11764352
As there says, without this, gmp (after glibc built) tests crashed
- segfault.
Now that we have a way to alter /bin/sh in chroots on non-NixOS Linux
platforms, it may be useful to have access to stdenv.shell package and to
static bash contained in bootstrap tools. So make them accessible via stdenv
attribute set.
libstdc++ and libmudflapth link to the dynamic loader; if the
bootstrap uses another dynamic loader name, and the rpath of these
libs isn't changed, they will fail to load.
Conflicts:
pkgs/development/compilers/gcc/4.6/default.nix
pkgs/development/compilers/gcc/4.7/default.nix
The 4.7 had some weird parameters added in crossAttrs; I've removed
them, but I don't understand where they come from.
This is for consistency with terminology in stdenv (and the terms
"hostDrv" and "buildDrv" are not very intuitive, even if they're
consistent with GNU terminology).
This allows various applications. It allows users to set global
optimisation flags, e.g.
stdenv.userHook = ''NIX_CFLAGS_COMPILE+=" -funroll-loops"'';
But the impetus is as an alternative to issue #229, allowing impure
stdenv setup for people who want to use distcc:
stdenv.userHook = "source /my/impure/setup-script.sh";
This is probably a bad idea, but at least now it's a bad idea in
people's configuration and not in Nixpkgs. :-)
This adapter causes the resulting binaries to have debug info and no
optimisations. Example use (in all-packages.nix):
foo = callPackage ./foo.nix {
stdenv = keepDebugInfo stdenv;
};
If the environment variable HYDRA_DISALLOW_UNFREE is set to "1", then
evaluation of a package with license "unfree" will throw an error.
Thus such packages or any packages that depend on them will fail to
evaluate.
what the new nix thinks the fuloong is.
Anyone having the old nix should use a nixpkgs previous to this change to build
the new nix. And then, with the new nix, he can use any newer nixpkgs revision.

this because 'ld' wants to know the path of every library involved in a dynamic

call the loader for it to resolve the library rpaths, but this is not the case

- 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.
svn path=/nixpkgs/branches/stdenv-updates/; revision=18550
- 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.

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.

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.
svn path=/nixpkgs/branches/stdenv-updates/; revision=18471
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.
svn path=/nixpkgs/branches/stdenv-updates/; revision=18449
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.
