Add it explicitly on the compile command `-liconv`
Use nix and then you can control the build environment in a totally controllable and reproducible manner. This is actually easier than it sounds: `curl https://nixos.org/nix/install | sh` and `nix-env -I ghc`. If you get the same error with that then we can try adding `iconv` explicitly.

I have a conundrum on which advice would be appreciate. Does
anyone know how to successfully install ghc on OSX
I've tried various binary instalation routes:
macports, brew, direct binary downloads from haskel.org
All have the same result. when I try to compile a basic hello world program
I get

Undefined symbols for architecture x86_64:
"_iconv", referenced from:

I've triedgiong through ghcup

8.8.4
8.6.5.
8.10.2
8.10.7
9.0.1

all have the same problem.
I'd be happy to build from source. Small problem: what Haskell compiler do
I use?

Any advice on installs that works along with any changes to paths to avoid
the iconv problems would be appreciated as currently my Haskell-related
activities have come to a grinding halt. Switchig to a different OS would
be nice but its not a
feasible option a at present.Writing a compiler is starting to look
attractive..

thanks
David
