store, rather than outside (such as /bin/sh).
For instance, the Nix expression for the ATerm library now looks
like this:
{stdenv, fetchurl}:
stdenv.mkDerivation {
name = "aterm-2.0.5";
builder = ./builder.sh;
...
}
where `mkDerivation' is a helper function in `stdenv' that massages
the given attribute set into using the bash shell that is part of
the standard environment:
mkDerivation = attrs: derivation (att s // {
builder = pkgs.bash ~ /bin/sh;
args = ["-e" attrs.builder];
stdenv = (...);
system = (...).system;
});
Note that this makes it unnecessary to set the `stdenv' and `system'
attributes, since `mkDerivation' already does that.

whether the system header file directory actually exists (when
calling fixinc), so passing a non-existent directory no longer
works. Instead we make a empty dummy directory.

builders for typical Autoconf-style to be much shorten, e.g.,
. $stdenv/setup
genericBuild
The generic builder does lots of stuff automatically:
- Unpacks source archives specified by $src or $srcs (it knows about
gzip, bzip2, tar, zip, and unpacked source trees).
- Determines the source tree.
- Applies patches specified by $patches.
- Fixes libtool not to search for libraries in /lib etc.
- Runs `configure'.
- Runs `make'.
- Runs `make install'.
- Strips debug information from static libraries.
- Writes nested log information (in the format accepted by
`log2xml').
There are also lots of hooks and variables to customise the generic
builder. See `stdenv/generic/docs.txt'.
* Adapted the base packages (i.e., the ones used by stdenv) to use the
generic builder.
* We now use `curl' instead of `wget' to download files in `fetchurl'.
* Neither `curl' nor `wget' are part of stdenv. We shouldn't
encourage people to download stuff in builders (impure!).
* Updated some packages.
* `buildinputs' is now `buildInputs' (but the old name also works).
* `findInputs' in the setup script now prevents inputs from being
processed multiple times (which could happen, e.g., if an input was
a propagated input of several other inputs; this caused the size
variables like $PATH to blow up exponentially in the worst case).
* Patched GNU Make to write nested log information in the format
accepted by `log2xml'. Also, prior to writing the build command,
Make now writes a line `building X' to indicate what is being
built. This is unfortunately often obscured by the gigantic tool
invocations in many Makefiles. The actual build commands are marked
`unimportant' so that they don't clutter pages generated by
`log2html'.

checked whether absolute paths passed to gcc/ld refer to the store,
which is wrong: they can also refer to the build tree
(/tmp/nix-...).
* Less static composition in the construction of stdenv-nix-linux:
gcc-wrapper and generic are now passed in as arguments, rather then
referenced by relative path. This makes it easier to hack on a
specific stage of the bootstrap process (before, a change to, e.g.,
generic/setup.sh would cause all bootstrap stages to be redone).

- gcc/ld-wrappers have been factored out into a separate
derivation. This allows a working gcc to be installed in the user
environment. (Previously the Nix gcc didn't work because it
needed a whole bunch of flags to point to glibc.)
- Better modularity: packages can specify hooks into the setup
scripts. For instance, setup no longer knows about the
PKG_CONFIG_PATH variable; pkgconfig can set it up instead.
- gcc not longer depends on binutils. This simplifies the bootstrap
process.

/usr/lib/crt1.o, while it should be using $glibc/lib/crt1.o. This
quick hack (prepending $glibc/lib to the GCC search path using "-B")
fixes the problem, but a better solution to prevent this sort of
thing is to remove these static paths from gcc.
Note: this problem was found using the pure UML Nix environment
(where we don't have /usr/lib).

(stdenv) on Linux. The previous 1-stage bootstrap was insufficient,
because the tools in stdenv where built by native tools. For
instance, the Nix bash had a reference to /lib/libncurses. This
doesn't happen with a 2-stage bootstrap, since the bash built in
stage 2 will be built with the gcc built in stage 1, which doesn't
search in the "standard" locations.
Motto: "Disparaging the boot is a bootable offense."
