I am running OS X 10.6.8 with Xcode 4. I have the Haskell Platform installed, ghc v. 7.0.3.
I cannot get the llvm haskell bindings to install correctly using cabal. I get this at the tail end of messages from cabal:
checking llvm-c/Core.h usability... yes checking llvm-c/Core.h presence... yes checking for llvm-c/Core.h... yes checking llvm/Support/DynamicLibrary.h usability... yes checking llvm/Support/DynamicLibrary.h presence... yes checking for llvm/Support/DynamicLibrary.h... yes checking for LLVMModuleCreateWithName in -lLLVMCore... no checking for LLVMModuleCreateWithName in -lLLVMCore... no
Here, configure has found LLVM C library, but the found library does not have the functionality required.
configure: error: could not find LLVM C bindings
So here configure reports that it cannot find LLVM C library.
cabal: Error: some packages failed to install: llvm-0.10.0.1 failed during the configure step. The exception was: ExitFailure 1
Has anyone had any luck getting this set up? Googling leads me to some rather terse comments that the Apple llvm installation does not include the required llvm libraries. I hate to install a separate set of llvm stuff with macports, or the llvm repository, because I fear that I might run into all kinds of puzzling conflicts with the Apple stuff.
It looks like your guess is correct - the LLVM C library you have installed isn't what the Haskell bindings want.
Ideas?
This might be where someone else jumps in - I've had luck with MacPorts + Haskell in the past, but it can be a struggle. I've never tried this particular case. In particular the iconv situation is nightmarish (Apple iconv and MacPorts iconv are not ABI compatible), but that's really a special case of the more general problem of building things against MacPorts.
