* 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'. svn path=/nixpkgs/trunk/; revision=845

longDescription = ''
The PCRE library is a set of functions that implement regular
expression pattern matching using the same syntax and semantics as
Perl 5. PCRE has its own native API, as well as a set of wrapper
functions that correspond to the POSIX regular expression API. The
PCRE library is free, even for building proprietary software.
