I am afraid that it has to use ghc-api-compat-9.0.1 instead 8.10.7 cause the build is using ghc 9:

I bet you just have to copy paste the ghc-api-compat override into the ghc9 .nix file, set the version to 9.0.1, replace some characters in the hash with 0 so it will refetch, rebuild, fix the hash, then it might work then?

It seems that the way that the ghc-api-compat thing works is that it needs to be built on a matching ghc version to its own version, but presumably it offers stable APIs such that a project could conceivably build with multiple versions of ghc-api-compat.

i am afraid that does not exist, could the nix script choose the right ghc-api-compat from the actual ghc, as the versions match exactly?

anyway i would no spend much time on this, ghc-api-compat will be removed with #2128

[jneira]

i am not able to make nix compute the hash auto cause i am on windows and cabal2nix is not helping me either so would be great if someone could give me the hash or complete the pr

[jneira]

and i cant push to @lf- branch
