Peter Simons 944ae2e5ff pkgs/build-support/cabal: disable split-objects for GHC 7.7 builds to work around broken compiler 2013-04-24 13:21:05 +02:00
Peter Simons 6f1cec9acb haskell-packages.nix: fix the implementation of 'cabalNoTest'
The previous implementation used the following tying-the-knot trickery to
override 'doCheck' to false for the given build:

  cabalNoTest = {
    mkDerivation = x: rec {
      final = self.cabal.mkDerivation (self: (x final) // { doCheck = false; });
    }.final;
  };

That seemed to work, but for some reason it caused trouble with some builds --
not all -- that use jailbreakCabal. The problem was the 'stdenv' attribute
couldn't be evaluated properly anymore:

  infinite recursion encountered

I tried to figure out why this happens, but eventually gave up. The new
implementation passes an argument called 'enableCheckPhase' to the Cabal
builder, which determines whether the user-specified doCheck value has any
effect or not. Now, a normal override can be used to disable unit testing.

Peter Simons 32fb6ed5e3 pkgs/build-support/cabal: disable doCheck by default on GHC 7.0.x platforms
Trying to run the unit tests with GHC 7.0.4 causes so many builds to
fail that it's probably not worth-while.

Peter Simons ffd11da9d9 pkgs/build-support/cabal: enable 'doCheck' only on GHC versions 7.x or later
Older GHC's come with a version of Cabal that doesn't even understand the
--{enable,disable}-tests command line arguments.

Peter Simons fcd895afb3 pkgs/build-support/cabal: disable the split objects feature on Darwin by default
According to <http://hackage.haskell.org/trac/ghc/ticket/4013>, this
feature won't work with XCode versions older than 3.2.

This means that Mac users will have considerably larger binaries because
some build-time dependencies (such as HTTP) will be mis-detected as
run-time dependencies.

Peter Simons dd13aa9c94 pkgs/build-support/cabal: add 'enableSplitObjs' field to enable/disable object splitting
This patch configures all Cabal builds with '--enable-split-objs' unless the
Nix expression explicitly sets "enableSplitObjs = false". The Cabal manual [1]
describes this option as follows:

 | The GHC -split-objs reduces the final size of the executables that use the
 | library by allowing them to link with only the bits that they use rather
 | than the entire library. The downside is that building the library takes
 | longer and uses considerably more memory.

One immediate benefit of this change is that the 'darcs' closure defined in the
top-level no longer refers to GHC. The same is probably true with other
executable packages.

Trivial solution.

Eelco Dolstra ab3eeabfed Rename buildNativeInputs -> nativeBuildInputs
Likewise for propagatedBuildNativeInputs, etc.  "buildNativeInputs"
sounds like an imperative rather than a noun phrase.

Peter Simons 77a21eed08 Clean up changes to the Cabal builder, which needed to be done in an awkward fashion to avoid a complete re-build of all Haskell packages. 2012-09-11 16:53:48 +02:00
Peter Simons 470ade254e Add support for jailbreak-cabal utility to the Cabal builder.
Jailbreaks-cabal allows Nixpkgs maintainers to quick-fix builds of packages
that over-specify their version requirements by removing the version
restrictions of all dependencies from the Cabal file. Set

  jailbreak = true

in the build expression to activate this feature.

Peter Simons cecff49b34 Moved the cabal build driver function from development/libraries/haskell/cabal to build-support/cabal.
This change also resolves the "cabal" vs. "Cabal" ambiguity on file systems
that don't distinguish case.
