Hi Boldizsár,

I infer from the path names that you are on windows? It's likely that you
have not correctly configured your machine, since this commit passed
validation on windows here:

Can you double check that you have followed the instructions here:

> Before the errors I have a warning:

Warning: -rtsopts and -with-rtsopts have no effect with -no-hs-main.
>     Call hs_init_ghc() from your main() function to set these options.

This is normal.

> The only change I made is fixing some simple type errors in
> utils/ghc-cabal/Main.hs that stopped compilation.
> It is very unusual for HEAD to fail to compile, and CI indicates that it
does compiles on the test systems in this case.

Good luck!
