Peter Simons 631ad32b5d pkgs/build-support/cabal: the configure-phase warning check can be
disabled by setting 'strictConfigurePhase' to 'false'

This is necessary for some packages, like dns, because cabal warns about
multiple versions of the same dependency being used, but the usage is fine,
actually, so we want the build to succeed. Packages that depend on 'doctest'
also have this issue <https://github.com/sol/doctest-haskell/issues/69>.

Peter Simons 7d577eb822 build-support/cabal: recognize the "this package indirectly depends on
multiple versions of the same package" warning from Cabal and abort the
build if it occurs.

Benno Fünfstück ebdff3841a haskell: Propagate cabal dependencies to user env
Before this commit, if a haskell library X depends on Y, and X was added to
systemPackages, only X would be available in the user environment. Y
would not be avialable, which causes X to be broken. This commit solves
the issue by setting propagatedUserEnvPkgs to all packages X depends
on when X is a library.

Peter Simons ea20904aef cabal: add support for the enableStaticLibrary flag to enable/disable building of static libraries
Disabling static libraries is supported only in GHC 7.7 or later.

Peter Simons d64917ad17 Back-port Haskell-related improvements from stdenv-updates.
* There now is full support for building Haskell packages as shared libraries
   for GHC versions 7.4.2 or later. The Cabal builder recognizes the following
   attributes:

    - enableSharedLibraries configures Cabal to build of shared libraries in
      addition to static ones. This option requires that all dependencies of
      the package have been compiled for use in shared libraries, too.

    - enableSharedExecutables configures Cabal to prefer shared libraries when
      linking executables.

   The default values for these attributes are arguments to the haskellPackages
   expression.

 * Haskell builds now run in a LANG="en_US.UTF-8" environment to avoid plenty
   of build and test suite errors. Without this setting, GHC seems unable to
   deal with the UTF-8 character encoding that's generally considered standard
   in the Haskell world.

 * The Cabal builder supports a new attribute 'testTarget' to specify the exact
   set of tests to be run during the check phase.

 * The ghc-wrapper attribute ghcVersion has been removed. Instead, we use the
   ghc.version attribute, which exists in unwrapped GHC derivations, too.

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.

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.
