Hi folks, I'm trying to build ghc-8.10.2 from source. The configure step seemed to go well, as shown below. The error during the build is shown after that. I'm afraid I don't know how to make heads or tails of the error, so any help would be appreciated. Thanks, Scott ---------------------------------------------------------------------- Configure completed successfully.
