Re: Glasgow-haskell-users Digest, Vol 212, Issue 5

[David Duke]

Thanks Dominic George for that. I had env var set. iconv --version gives
GNU libiconv 1.16
I created a clean shell so env vars set other than PATH and installed using
the tarball on the link George  provided.
It appeared to install okay . However trying to compile throws up:

cannot satisfy -package-id ghc-9.0.1
compiling with -v:


Loaded package environment from
/Users/scsdjd/.ghc/x86_64-darwin-9.0.1/environments/default

Glasgow Haskell Compiler, Version 9.0.1, stage 2 booted by GHC version 8.8.4

*** initializing unit database:

There is no package.cache in /usr/local/lib/ghc-9.0.1/package.conf.d,
checking if the database is empty

There are no .conf files in /usr/local/lib/ghc-9.0.1/package.conf.d,
treating package database as empty

Using binary package database:
/Users/scsdjd/.cabal/store/ghc-9.0.1/package.db/package.cache

package flags [-package-id ghc-9.0.1{unit ghc-9.0.1 True ([])},

David

[George Colpitts]

Hi David

I've also used ghc for years on Mac OS and have also never seen this
problem. I don't use nix. Currently I am on ghc 9.0.1. and Mac OS 11.6. I
installed from

https://downloads.haskell.org/ghc/9.0.1/

More specifically ghc-9.0.1-x86_64-apple-darwin.tar.xz



Are any of the following env variables defined on your system?

   LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, and DYLD_FALLBACK_LIBRARY_PATH

None are defined on my system which I think is normal.

When you type

  iconv --version

What output do you get? I get

 iconv --version
iconv (GNU libiconv 1.11)

Not sure if my questions will help but I think there is something unusual
about your system configuration.

[Dominic Steinitz]

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.
