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'.

* genericBuild performs a generic build of (typically) autotool-style
|
|
packages
|
|
|
|
|
|
* unpack phase
|
|
|
|
** may be overriden by setting $unpackPhase to point at a function that
|
|
unpacks the source (which should set $sourceRoot)
|
|
|
|
** the generic unpacker unpacks all sources specified by $srcs, or
|
|
$src if $srcs is empty
|
|
|
|
** supports tar, bzipped tar, gzipped tar, compressed tar, zip
|
|
|
|
** zip must be in scope (in $buildinputs)
|
|
|
|
** additional file types may be supported by setting $findUnpacker,
|
|
which is called with a single argument specifying the file to be
|
|
unpacked
|
|
|
|
** $findUnpacker should set $unpackCmd, specifying the full command to
|
|
unpack the file (must include the file name)
|
|
|
|
** alternatively, $unpackCmd can be set before calling the generic
|
|
builder (e.g., 'unpackCmd="unrar x $src"'); this only works if
|
|
there is a single source file
|
|
|
|
** the generic unpacker then sets $sourceRoot to the name of the
|
|
directory created by unpacking the source archives
|
|
|
|
** the source archives should produce only one directory
|
|
|
|
** alternatively, $setSourceRoot may be set to a function that sets
|
|
$sourceRoot
|
|
|
|
|
|
* the generic builder then chdirs to $sourceRoot
|
|
|
|
|
|
* patch phase (skipped if neither $patchPhase nor $patches are set)
|
|
|
|
** may be overriden by setting $patchPhase to point at a function that
|
|
unpacks the source (which should set $sourceRoot)
|
|
|
|
** if the $patches variable is set, it runs `patch -p1 < ...' in
|
|
$sourceRoot for each element in $patches (the `patch' command
|
|
should be in $PATH; note that it isn't in the standard environment)
|
|
|
|
|
|
* configuration phase
|
|
|
|
** may be overriden by setting $configurePhase to point at a function
|
|
|
|
** calls $preConfigurer first, if set (useful for running
|
|
autoconf/automake)
|
|
|
|
** the configure script is specified by $configureScript, which
|
|
defaults to ./configure
|
|
|
|
** if no executable file exists at $configureScript, does nothing
|
|
|
|
** if a file ./ltmain.sh exists and $dontFixLibtool is not set, calls
|
|
function fixLibtool to remove its default search path (/usr etc.)
|
|
|
|
** adds "--prefix=$out" to $configureFlags unless $dontAddPrefix is
|
|
set
|
|
|
|
** calls $configureScript with $configureFlags
|
|
|
|
** calls $postConfigurer, if set (useful for any last-minute patches
|
|
prior to building)
|
|
|
|
|
|
* build phase
|
|
|
|
** may be overriden by setting $buildPhase to point at a function
|
|
|
|
** runs make with flags $makeFlags
|
|
|
|
|
|
* install phase
|
|
|
|
** may be overriden by setting $installPhase to point at a function
|
|
|
|
** runs make with flags $installFlags
|
|
|
|
** unless $dontStrip is set or $NIX_STRIP_DEBUG is not 1, finds all *.a
|
|
files in $out and runs "strip -S" on them (executables and dynamic
|
|
libraries can be stripped automatically by setting NIX_STRIP_DEBUG
|
|
to 1 (default))
|
|
|
|
** if $propagatedBuildInputs is set, its contents are written to
|
|
$out/nix-support/propagated-build-inputs
