bash: hadrian/build.sh: No such file or directory

[zeta-00]

hello there, i decided to build ghc with nix again(after about 2 months), but for some reason now that error is being thrown when i run: hadrian/build.sh -j4 --flavour=perf --build-root=_mybuild -c , this error never happened before so i'm not sure what's going on? also when is ghcide expected to be up and running again? i really need that tool. (thank you for taking the time to read this issue)
also, whenever i go into nix-shell it shows this weird output:

[zeta@nixos:/ghc]$ nix-shell ghc.nix/
Recommended ./configure arguments (found in $CONFIGURE_ARGS:
or use the configure_ghc command):

Hey @zeta-00 ,

• hadrian/build.sh was renamed to hadrian/build.
• ghcide will be back once ghcide-nix supports GHC 8.8 o higher. You can build ghcide manually with cabal or stack. You only have to make sure you're using the same version as you use to build GHC.
• The "weird output" is for configuring and building a GHC that works outside of the nix-shell. (By setting absolute paths to needed libraries into the build config.)

@supersven , hello there, thanks for letting me know about the renamed command, and i'll contact the ghcide-nix devs to see what is the progress of getting ghcide working ghc 8.8

[zeta-00]

@supersven , ok, i talked with the people from ghcide-nix, and they say ghc 8.8 is supported by ghcide-nix, but i'm going to have to build ghcide from source until you guys get it fixed: https://github.com/digital-asset/ghcide/issues/532

[supersven]

@zeta-00 ,
When cachix/ghcide-nix#32 is merged and cachix/ghcide-nix#3 is closed, we can easily re-enable the ghcide support in ghc.nix. It's only commented out.

Thanks for pushing this issue forward. I'm looking forward to see ghcide support back in ghc.nix, too... 😃

[zeta-00]

@supersven , that sounds good, can't wait until ghcide in ghc.nix is up and running again, thanks again for the help

[zeta-00]

@supersven , hello again, just wondering what's the progress of getting ghcide working with ghc.nix? it's been almost a month

[supersven]

Hey @zeta-00 ,

Well, the state didn't change much: GHC >= 8.8 is still not supported by the master branch of ghcide-nix. As (IMHO) we don't want to rely on development branches, we're still waiting ...

As a work-around you can manually build ghcide. (You have to use the same GHC version that you're planning to use for GHC development, i.e. for compiling stage0.)

[supersven]

Hey @zeta-00 ,

Short update: #73

As re-enabling ghcide is tracked by a dedicated ticket now, can we close this ticket?

[zeta-00]

@supersven , it looks like there has been good progress:
cachix/ghcide-nix#32

thanks for the update, and go ahead and close this issue
