the problem here is that in Guix we link Haskell executables dynamically
and sometimes move static libraries to a separate output without updating
the config file (because otherwise it would create a reference, which
we’re trying to avoid to save space).
It works fine for me using
guix shell --pure ghc ghc-comonad gcc-toolchain@10 -- ghc --make
-dynamic -v LinkMe.hs
Cheers,
Lars
