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\")";

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.

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'.
