Error encountered while installing GHC about ghc-musl

[utdemir]

Hey, thanks for taking time to open an issue!

As far as I can see, the curious part is that stack is trying to build the GHC itself, instead of using the one from the compiler. This is likely to fail, as the container is missing a lot of tooling for that. So the ideal is to convince stack to use the compiler that is already in the container. Which stackage resolver you are using?

I saw this on the "details" section:

/usr/local/.ghcup/ghc/9.4.4/bin/ghc-9.4.4": PrettyException UnwantedCompilerVersion

So, can you try convincing stack to use the "GHC 9.4.4"? A couple of ways I can think of:

• Use a resolver that uses GHC 9.4.4
• I think you could also convince stack to be more lenient when checking compiler versions. See the compiler-check section on stack docs.

Hope it helps!
