Hi David I am a long time user of ghc on OSX. I have seen that problem but never on native OSX only when using nix (and then I added it explicitly). Two things spring to mind: 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
