I installed GHC on Windows 11 yesterday, via ghcup:
$ uname -a

Today, I tried using GHC. I tried building a simple “Hello, World!” program (the default program created by cabal init). However, it fails with linker errors:
$ cabal-build

In order, the following will be built (use -v for more details):

Any idea what causes these and how to fix them?
Searching online reveals that other people are also getting this error (not with Haskell, but with other languages like C++ and Rust). However, none of the pages I’ve looked at so far give a clear explanation of what’s wrong and how to fix it.
