It's likely that you have not correctly configured your machine, since this commit passed validation on windows here: https://phabricator.haskell.org/B19134 Can you double check that you have followed the instructions here: https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows

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! Regards, Doug WIlson
