Better error message for unplanned components

1

While using `cabal-to-nix` to replace a package in an existing project @shlevy and I had an issue where we got an error similar to #1372. It turned out that we...

Currently when a component depends on the library of another package (`build-depends:`), nix-tools adds the package itself to `depends` rather than the library. It would simplify haskell.nix if it instead...

To reproduce this issue use https://github.com/input-output-hk/haskell.nix/pull/963 and remove [the work around module from `test/cabal-sublib/default.nix`](https://github.com/input-output-hk/haskell.nix/blob/76e8a9bf9f3c8195ceae2bc549ed31da77e446b9/test/cabal-sublib/default.nix#L13-L19) To view the `plan.json` file: ``` jq . $(nix-build ./default.nix --argstr compiler-nix-name ghc8102 -A cabal-sublib.ifdInputs.plan-nix.json) |...

Cabal 3.8 expects `pkg-config --libs --static` to always work.

dwarf version of ghc 9.2.1 fails to build on hydra

Hydra error is `Output limit exceeded`. We suspect this is because the outputs of the derivation total more than 4GB. ``` $ du -sh $(nix-build -A pkgs-unstable.haskell-nix.compiler.ghc921.dwarf) $(nix-build -A pkgs-unstable.haskell-nix.compiler.ghc921.dwarf.doc)...

One way to reproduce enable the `cabal-22` test for ghcjs on darwin in `test/default.nix` and run: ``` nix-build release.nix -A R2003.ghc884.darwin.ghcjs.tests.cabal-22.run --show-trace ``` ``` unpacking sources unpacking source archive /nix/store/0fvszhwxzibkx1kwmlp8cndz8airff9n-project-test-unit-0.1.0.0-js-unknown-ghcjs-js-unknown-ghcjs...
