#8837: GHC 7.8.1-rc2 requires /usr/local/lib/libgmp10.10.dylib ------------------------------------------+-------------------------------- Reporter: awick | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.8.1-rc2 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 Type of failure: Installing GHC failed | (amd64) Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: ------------------------------------------+-------------------------------- Comment (by thoughtpolice): Hmmmm... 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
