Re: [Haskell-cafe] GHC 6.12 on OS X 10.5

not sure if this helps, but try: # ports share lib export export CPATH=~/local/include export LIBRARY_PATH=~/local/lib export LD_LIBRARY_PATH=~/local/lib export DYLD_LIBRARY_PATH=~/local/lib replace ~/local/ with your ports path On Tue, Dec 22, 2009 at 5:43 AM, Tom Tobin wrote:

I thought I'd record my upgrade exerience (so far) in case anyone else finds it useful, and (more selfishly) in case anyone has some helpful advice. Summary of situation

You just described what I went through last night with GHC 6.12 before giving up and going to bed, except that I'm on Snow Leopard (OS X 10.6).  I got the "undefined symbols" errors when trying to compile cpphs, which came up at some point in the build process when trying to install Happstack via cabal 0.8.0.  I was wondering if if something was getting confused between my MacPorts libraries and OS X, and your experience certainly makes it seem that way; I have the MacPorts paths set up in my .cabal/config file as extra-include-dirs and extra-lib-dirs, otherwise I can't get particular libraries (e.g., pcre-lite) to compile.

I'm going to wipe my .cabal and .ghc and try from scratch to build as much as possible without the MacPorts paths, only re-adding them for single builds as necessary; I'll write back after I see how that goes.

This time, after wiping .ghc and .cabal, I immediately did "cabal update" followed by "cabal install happstack" (without going and changing the extra-include-* settings in .cabal/config to point at the MacPorts dirs).  cpphs compiled fine this time, but I got a failure due to haskell-src-exts not building; haskell-src-exts in turn complained that happy wasn't installed.  I went and installed happy, then haskell-src-exts (which installed v1.3.4), and then did "cabal install happstack" again which installed haskell-src-exts v1.0.1 (I guess GHC understands how to deal with two different installed library versions?).

This time the install died on HJScript:

********** [ 2 of 26] Compiling HJScript.Monad   ( src/HJScript/Monad.hs, dist/build/HJScript/Monad.o )

src/HJScript/Monad.hs:51:10:    A pattern match on a GADT requires -XGADTs    In the pattern: EmptyBlock    In the definition of `mappend': mappend EmptyBlock b = b    In the instance declaration for `Monoid (Block ())' cabal: Error: some packages failed to install: HJScript-0.4.5 failed during the building phase. The exception was: ExitFailure 1 **********

I have no idea what to do next, so I'll probably bring this particular issue up on the Happstack list next.

My questions at this point:

1) The original problem definitely looks like it's related to library confusion between the system libs and the MacPorts libs.  Is there any way of sanely handling this when I need a library that's available through MacPorts but not OS X's system libs?  (MacPorts' insistence on maintaining an entirely separate library stack from the OS X system libraries is starting to make me crazy.  ::sigh::)

2) Regarding haskell-src-exts: why wasn't happy wasn't pulled into the dependency graph in the first place? _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
