"installed package ghc-9.8.1 is broken due to missing package semaphore-compat-1.0.0-inplace" when trying to use GHC 9.8 with weeder

[ocharles]

Describe the bug

The following PR attempts to update the Nix shell for Weeder to use GHC 9.8: ocharles/weeder#143

This fails with:

       > 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-9.8.1 is broken due to missing package semaphore-compat-1.0.0-inplace
       >

I'm not sure what to do to fix this.

Steps To Reproduce

Run nix build --print-build-logs in a clone of ocharles/weeder#143

Expected behavior

Weeder is built with GHC 9.8

I think semaphore-compat is a new boot package in 9.8, so maybe we need to adjust something in here?

For Weeder, the following appears to solve this:

          modules = [
            {
              reinstallableLibGhc = false;
              nonReinstallablePkgs = [
                "rts" "ghc-prim" "integer-gmp" "integer-simple" "base"
                "deepseq" "array" "ghc-boot-th" "pretty" "template-haskell"
                "ghc-bignum" "system-cxx-std-lib" "ghc" "binary" "bytestring" "containers" 
                "directory" "exceptions" "filepath" "hpc" "process" "semaphore-compat" "stm" 
                "time" "transformers" "unix" "mtl"
              ];
            }
