So, this was an error on my part, but it makes me think of something I'm not sure we considered: - Right now, if you *don't* have GMP available at build time, and you use the in-tree GMP, GHC will link it statically into your applications. That is, GHC will build GMP locally to use it, and resulting applications won't have a dynamic link to `libgmp.so`. - If you have an external GMP at build time, then it will link resulting binaries against that. Since GHC self-bootstraps as you can see, this includes GHC itself. This happened to me because I did `brew install gmp` to test something. Adam, I can provide another binary in the mean time with the caveat it statically links to GMP. Is this acceptable? For some people I know (out of principle or otherwise) this isn't, and they will want to dynamically link, so perhaps there should be two for now. Frankly, the binary proliferation here is a bit silly almost... we should really carefully evaluate what to do with GMP etc in a discussion in the future. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8837#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Personally, I'd much prefer GHC to include an "extra" version of GMP than assume the right one is around on a Mac. From my point of view, either using a statically linked set of binaries or just including a copy of libgmp.10.dylib are equally fine. Ideally, it'd be nifty if the installer did a check for a local version. If there was one, it'd point the installed binaries to that. If not, then it'd have a spare copy it could install for GHC. But I don't know how hard that redirection would be, and for now, I suspect just always including GMP would be easier. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8837#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Theoretically you could do something I gues to change the rpath (perhaps `nix` does this for OS X already) but that seems fragile to incorporate right now - plus we need to ensure GHC itself does the right thing once this is detected. It sounds like a bit of work. I think the better thing to do would be to investigate cleaning up the in- tree GMP build to install a `.dylib` which we can fall back on, since we need the in-tree build for Windows and generally OS X (as it doesn't come along). Linux is not so much of a problem. In the mean time - I've updated the binaries for the RC2 download. They link statically just like RC1. Do give them a go. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8837#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
