Hello, in case someone else hits this problem I was able to fix it by
installing the latest haskell platform via macports.
- I uninstalled ghc "sudo /Library/Frameworks/GHC.framework/Tools/Uninstaller"
- deleted ~/.ghc and ~/.cabal
- did a "sudo port install haskell-platform" (be prepared for this to
take a couple of hours). ghc --version gives 6.10.4
- cabal install llvm
I still don't know the root cause of the build error but now the llvm
examples build and run with no errors.

Hello All,
I'm trying to get up and running with the very interesting llvm package[1] but I'm running into problems during the linking stage.
keith@sugarglider-2:~/projects/third-party/llvm-hs-bindings/examples/> make clean all rm -f HelloJIT Fibonacci BrainF Vector Array DotProd Arith Align Struct Varargs *.o *.hi *.s *.bc Fib *.exe *.exe.manifest *~ ghc -Wall -optl -w --make -o HelloJIT.exe -main-is HelloJIT.main HelloJIT.hs [1 of 1] Compiling HelloJIT ( HelloJIT.hs, HelloJIT.o ) Linking HelloJIT.exe ... Undefined symbols: "_LLVMAddCondPropagationPass", referenced from: _ssCM_info in libHSllvm-0.7.1.1.a(Scalar.o) ld: symbol(s) not found collect2: ld returned 1 exit status make: *** [HelloJIT.exe] Error 1
It's probably something very simple that I'm doing wrong since this is my first Haskell build linking against foreign libs. Do you know what I might be doing wrong?
Here are the versions: Mac OS X 10.5.8 GHC 6.10.1 (waiting out a leopard installer bug [2]) llvm-2.7 installed to default location llvm package version 0.7.1.1
Thanks!
BTW, the combination of this package plus the awesome Haskell parsers seem to make for a great compiler construction kit. I'm looking forward to playing around w/ llvm
