* The stdenv setup script now defines a generic builder that allows
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'.
