Failed to build latest stable GHC on FreeBSD with Hadrian

[Jeffrey Young]

Hi Alexis,

This line shows the error:

> | Configure package 'ghc-bin'
> # cabal-configure (for _build/stage0/utils/haddock/setup-config)
> # cabal-configure (for _build/stage0/ghc/setup-config)
> hadrian: Encountered missing or private dependencies:
> ghc ==9.3.*

A package had a constraint on the ghc api to only accept ghc == 9.3.*. 
Since you are trying to build ghc 9.2 this fails. The package in 
question is printed by hadrian in this bit of your log:


> src/Development/Shake/Internal/Rules/Oracle.hs:159:32 in
> shake-0.19.4-9f51719be46f95213676da51d6a6626f69f0cfa15957aab44867ff78b757df38:Development.Shake.Internal.Rules.Oracle

> * Depends on: OracleQ (ContextDataKey (Context {stage = Stage0, package =

> Package {pkgType = Program, pkgName = "haddock", pkgPath =
> "utils/haddock"}, way = v}))

>    at need, called at src/Hadrian/Oracles/Cabal/Rules.hs:54:9 in

Notice the `pkgName` field in the `Package` record in the error that 
hadrian produced. It shows us that haddock was the cuplrit. Not sure 
why/how that cabal file got mixed up but I bet if you went to 
`${GHC_HOME}/utils/haddock/haddock.cabal` you'll find the constraint in 
question and should be able to switch it to `ghc==9.2.*` and rebuild 
according to the wiki.


Hope this helps,


Jeff
