We have been disabling terminfo in our GHC builds for cross compilers (windows and musl). This leads to an interesting problem when we `cabal configure` a project that needs `ghc`. The resulting `plan.json` might suggest that we should use the preexisting `ghc`. When it does though it does not include the `flags` needed to build it.
One fix would be to default the the `ghc` `terminfo` flag to `false` for cross compilers.
It turns out though that the reason we could not get the `terminfo` package to work with our cross compilers was that we were providing the `hostPlatform` `ncursers` when we needed the `targetPlatform` `ncursers`. Fixing that makes the cross compilers more like the native ones.
Also stops pinning wine to 5.4 on macOS (pinned version does not work there)
Fixes Windows cross compilation for GHC 9.0 and 9.2.
Updates wine to use the version that is included with the chosen Nixpkgs (it used to be pinned to an older version).
Moves the configuration of the GHC source into the GHC derivation. This should make adding Hadrian support easier.
Propagates library dependences (not just pkgconfig ones) on windows so that any DLLs in those libraries can be copied for TH evaluation and to the `/bin` directory of executable components.
Adds gcc and mfcgthreads as library dependencies on Windows so that the DLLs they include will be found.
Use `$pkgsHostTarget` (instead of `ghc-pkg`) to find all the DLLs can copy them to the `/bin` directory of executable components.
Adds support for __int128_t and __uint128_t to language-c to fix aarch64-darwin builds.
Fixed reinstalling packages that come with patched versions in ghcjs.
This change updates to the latest `nix-tools` to get the following fixes (there are 3 PRs in nix-tools, but just the one in haskell.nix to avoid having to update the materialized files multiple times):
## Better support for source repository packages
* https://github.com/input-output-hk/nix-tools/pull/107
Currently these are replaced by the `cabalProject` functions with regular `packages:` before running cabal configure. Cabal does not treat these the same (the setting of `tests:` and `benchmarks:` in the `cabal.project` file):
* The plan found by `cabalProject` may not match the one used when running `cabal`.
* The performance of the solver may not be consistent with running `cabal`.
This change replaces `source-repository-package` with another `source-repository-package` pointing at a minimal git repo.
## Only include planned components
* https://github.com/input-output-hk/nix-tools/pull/108
Only the components in the `plan.json` are now included in the haskell.nix cabal projects. This avoids missing dependencies attempting to build components that were not in the plan. Should fix#993.
## Pick latest packages
* https://github.com/input-output-hk/nix-tools/pull/109
When the same package occurs more than once in a `plan.json` file (perhaps because it is needed both by the project itself and by one of the `setup` dependencies or `build-tool-dependencies` of the project) the latest version will now be the one picked by haskell.nix. This is a work around for a common issue with `cabal-doctest` when cross compiling to windows (an old version of Win32 is used even if a newer one was required by the projects `constraints`).
The use of `sources.HTTP` to work around issues building GHC 9.0.1 causes a mismatch between `flake` based and non
`flake` based derivations.
The fixed version of HTTP is now in hackage so updating the internal hackage index state used haskell.nix removes the need for the HTTP source override.
See https://github.com/input-output-hk/nix-tools/pull/101
We should look up hsPkgs.${pkg-name}.components.exe.${component-name}
instead of including the package as a dependency.
Adding `hsPkgs.${pkg-name}` a tool it is not clear which executable in the package `haskell.nix` should choose.
Haskell.nix did not deal with this well and in fact it could lead to `nix-shell` crashing. For instance using `shellFor` to make a shell for building `haskell-language-server` with `cabal build` crashed as a dependency on `ghcide` the executable (by the `ghcide-bench` executable) caused infinite recursion. Allowing `ghcide-bench` to correctly depend just on `components.exes.ghcide` fixes this.
This PR also includes:
* Updated materialized files built with the new nix-tools and latest index-state
* Small update to GHCJS (pins happy) to fix issue that showed up when the materialization was updated
* A fix for the infinite recursion issue when updating materialized files (by adding ghc-boot-packages-unchecked).
* Performance fix for shellFor (checks just the names of component derivations when filtering).
This change introduces a `ghc8102-experimental` compiler-nix-name that behaves much like the `ghc8102` version but includes @JoshMeredith's patch `./patches/ghc/ghc-8.10-ubxt.patch` that writes the `cg_binds` field with:
```haskell
liftIO $ registerInterfaceDataWith "ghc/phase/core" hsc_env $ \bh ->
putWithUserData (const $ return ()) bh (map toIfaceBind $ cg_binds cg_guts)
```
Some of the places where we used to depend on the output of `plan-to-nix` containing the correct `nix-name` for the compiler have been update to avoid using incompatible interface files from the `compiler-nix-name = "ghc8102"` version of GHC.
Changes to the interface of haskell.nix (from the changelog.md file):
* Removed `sources.nixpkgs-default`, use `sources.nixpkgs` instead.
* Removed `./nixpkgs` directory, use `(import ./. {}).sources`
or `./nix/sources.nix` instead.
* Removes V1 interface for details on how to fix old code see:
https://github.com/input-output-hk/haskell.nix/issues/709
* Removed defaultCompilerNixName.
* cabalProject, cabalProject', hackage-project and hackage-package
now require a `compiler-nix-name` argument.
* `haskell-nix.tool` and `.tools` now require a `compiler-nix-name` argument.
New functions `p.tool` and `p.tools` (where p is a project) do not.
Like `shellFor { tools = ... }` they will use the compiler nix name
from the project (including stack projects where it is derived from
the resolver).
* `haskell-nix.alex` and `haskell-nix.happy` have been removed. Use
`p.tool "alex" "3.2.5"` or `shellFor { tools = { alex = "3.2.5"; } }`.
* `haskell-nix.nix-tools` -> `haskell-nix.nix-tools.ghc883` (it includes
the hpack exe now).
* `haskell-nix.cabal-install` ->
`p.tool "cabal" "3.2.0.0"` or `shellFor { tools = { cabal = "3.2.0.0"; } }`
* `haskell-nix.haskellNixRoots` -> `haskell-nix.roots ghc883` or `p.roots`
Other changes:
Adds hpack executable to the nix-tools derivations.
Adds a `cabal-hpack` test to make sure `hpack` works with
`cabalProject`.

checking materialization), by giving internal tools a per-compiler
attribute.
Uses happy 1.19.12 when building newer ghc versions.
Updates cabal-install 3.2.0.0 to use the source from github that
is compatible with ghc 8.10.1.
