installed package ghc-9.0.1 is broken due to missing package exceptions-0.10.4

[locallycompact]

Hi, I encountered this while converting a stack project that used ghc-tcplugins-extra, and it seems due to the dependency on ghc-9.0.1

Error:
    The following packages are broken because other packages they depend on are missing. These broken packages must be rebuilt before they can be used.
installed package ghc-9.0.1 is broken due to missing package exceptions-0.10.4

Here is a repo reproducing the behaviour with nix-build.

Best fix for this would be to set reinstallableLibGhc, but that does not work with GHC 9.0.1 yet. For now this should work:

 in pkgs.haskell-nix.project {
   # 'cleanGit' cleans a source directory based on the files known by git
   src = pkgs.haskell-nix.haskellLib.cleanGit {
     name = "haskell-nix-project";
     src = ./.;
   };
+  modules = [{
+    nonReinstallablePkgs = [
+      "rts" "ghc-heap" "ghc-prim" "integer-gmp" "integer-simple" "base"
+      "deepseq" "array" "ghc-boot-th" "pretty" "template-haskell"
+      # ghcjs custom packages
+      "ghcjs-prim" "ghcjs-th"
+      "ghc-bignum" "exceptions" "stm"
+      "ghc-boot"
+      "ghc" "Cabal" "Win32" "array" "binary" "bytestring" "containers"
+      "directory" "filepath" "ghc-boot" "ghc-compact" "ghc-prim"
+      # "ghci" "haskeline"
+      "hpc"
+      "mtl" "parsec" "process" "text" "time" "transformers"
+      "unix" "xhtml" "terminfo"
+    ];
+  }];
 }

Same with ghc921

[angerman]

@miuirussia does the proposed solution from @hamishmack work for 9.2.1?

[miuirussia]

no, and on 9.0.1 not working too

[angerman]

I see. Thanks. So this will need some investigation. Sorry for the inconvenience.

[avnik]

@angerman it works for me on 9.2.1 (today's snapshot of haskell.nix -- 82a20b7). Used example above with omitted ghcjs stuff, and disabled hoogle).

[dhess]

FYI, we're running into this issue now with latest haskell.nix and GHC 9.2.2. I think @hamishmack's workaround is working for us, though it's too early to be sure as we're running into other GHC 9.2-related issues and haven't been able to get a full build working just yet.

[RichardWarfield]

This also occurs for us with GHC 9.0.2 and GHC 9.2.2 when haskell-language-server is added to shell.tools. The nonReinstallablePkgs workaround is not working; we still see installed package ghc-9.0.2 is broken due to missing package exceptions-0.10.4.

[goertzenator]

This fix made polysemy-plugin and cleff-plugin work under ghc-9, but I am still having the same haskell-language-server problems as @RichardWarfield .

[TerrorJack]

After #1437 got merged, I managed to build haskell-language-server with ghc922 using only reinstallableLibGhc = true module, without specifying a long list of nonReinstallablePkgs.
