#8156: amd64 + in-tree gmp build broken -------------------------------------+------------------------------------- Reporter: errge | Owner: Type: bug | Status: patch Priority: low | Milestone: 7.10.1 Component: Build System | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 (amd64) Type of failure: Building GHC | Difficulty: Easy (less than 1 failed | hour) Test Case: | Blocked By: Blocking: | Related Tickets: #4022 #4366 #4374 -------------------------------------+------------------------------------- Comment (by carter): @Jan, LGPL is only compatible with BSD when we dynamically link it, statically linked LGPL forces the rest of the project (allegedly) to be GPL, which is incompatible with a parent project that is BSD, at least according to the FSF's overly aggressive reading of (L)GPL. We could expose the option for end users (with a flag) to statically link a GMP, but we can't distribute ourselves libs that are statically linked to GMP. basically, we could have a gmp dylib in our disto, but we'd still need to make sure we could dylink to other gmps, otherwise we'd be violating the LGPL (as i understand it.). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8156#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
