Matthew Bauer fd7a6ea0af haskell: make generic builder follow compiler’s shared config enableShared in generic-builder.nix should default to what the GHC compiler was compiled with. Add a passthru to all of the GHC compilers to hold the value of enableShared. If enableShared is not set in the GHC we just use false as the default value for enableSharedLibraries. Note: I may have missed some compilers. Only GHC & GHCJS are covered by this commit but this shouldn’t break evaluation of anything else.		2018-06-20 18:40:53 -04:00

New build system for GHCJS 8.2

ghcjs-8.2 reworked the build system, and now comes with its own small package set of dependencies. This involves autogenerating several sources and cabal files, based on a GHC checkout. callCabal2nix is off limits, since we don't like "import from derivation" in nixpkgs. So there is a derivation that builds the nix expression that should be checked in whenever GHCJS is updated.
