* Add native musl support
- adds haskellLibl.isNaviveMusl and related fixes (previously it was
assumed that for musl we always use cross-compilation)
- fixed some issues for musl intoduced in nixpkgs 20.03 (ssh/fetchcvs
infinite recursion, busybox pkgsMusl.pkgsStatic chain, etc.)
- cross-compilation fixes for ghc (absolute path for ar, always pass
target to configure, libffi and gmp packages for target platform) -
this needs more testing
* Better explanation for targetPlatform.{libffi, gmp}
* Ghc configure script now respect AR env variable

# This overlay helps accessing common executable components.
|
|
# Typically we want to make these available in a nix-shell
|
|
# created with shellFor. In most cases the package name
|
|
# will be the same as the executable, but we have a
|
|
# `toolPackageName` mapping to help when it is not.
|
|
#
|
|
# To get a single tool:
|
|
# haskell-nix.tool "cabal" "3.2.0.0"
|
|
#
|
|
# This does the same thing as:
|
|
# (haskell-nix.hackage-package {
|
|
# name = "cabal-install"
|
|
# version = "3.2.0.0"
|
|
# }).components.exes.cabal
|
|
#
|
|
# To get an attr set containing multiple tools:
|
|
# haskell-nix.tools { cabal = "3.2.0.0"; hlint = "2.2.11"; }
|
|
#
|
|
# To add tools to a shell:
|
|
# shellFor { tools = { cabal = "3.2.0.0"; hlint = "2.2.11"; }; }
|
|
#
|
|
# When used in shellFor the tools will be compiled with the same version
|
|
# of ghc used in the shell (the build ghc in the case of cross compilation).
|
|
#
|
|
# Instead of a version string we can use an attr set containing
|
|
# arguments that will be passed to `cabalProject`.
|
|
#
|
|
# For instance to specify the ghc used to compile. Use:
|
|
# haskell-nix.tool "cabal" {
|
|
# version = "3.2.0.0";
|
|
# ghc = haskell-nix.compiler.ghc883;
|
|
# }
