#7375: Building ghc fails because it is looking for an old version of libgmp --+- Reporter: mimosa | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler |Version: 7.4.2 Resolution: fixed| Keywords: Os: Linux| Architecture: Unknown/Multiple Failure: Building GHC failed | Difficulty: Unknown Testcase: | Blockedby: Blocking: |Related: 5743 --+- Comment(by simonmar): GHC is already following your suggestion: there is a copy of the gmp library in the build tree that we use if there isn't one on the system. It's in `libraries/integer-gmp/gmp`, and the same is true for `libffi` (although for the latter the problem has been that we are ''always'' using our copy of `libffi`, and some distros wanted us to use the system one instead, which is what #5743 is about). To avoid needing a hack, you just need to provide a stage 0 compiler that has the right dependencies. You can get one by building GHC and then making a binary distribution from it. Having done that, you're all set - no need for `libgmp.so.3` symlinks. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7375#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

As I said above, the GHC I built still seems to require the old gmp, but maybe there's something wrong with my package. For practical purposes, a package is a build that works on a particular system (in my case, a Linux distribution), but from the point of view of that system's packaging procedures, it is a link to the source code and a build script; taken together these should be capable of recreating the package from zero. However you go about it, GHC is going to need special treatment somewhere. For instance, the package source might include the locally built stage 0 compiler you suggest. Thank you for your helpful explanations. I'll talk to the Salix developers to see what solution they regard as ideal and try and deliver that for the next packaging cycle. Meanwhile, the existing package should be available from Salix repos shortly, and can be considered a Slackware package too. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7375#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler ___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

Comment(by hvr):
just a thought:
...what if the default-signature implementation would be only selectable
by using the `deriving` facilities for auto-derivable classes? I.e. by
using
{{{
#!hs
data A = A { unA :: Int }
deriving (Generic,Klass)
}}}
or
{{{
#!hs
data A = A { unA :: Int }
deriving Generic
deriving instance Klass A
}}}
would both result in `A` getting the default-signature based
implementation, wheras
{{{
#!hs
data A = A { unA :: Int }
deriving Generic
instance Klass A
}}}
would get the ordinary default implementation (as if the default-
signature implementation wasn't there). Wouldn't this help the issue at
hand by making the choice explicit?
