Bryan said a while ago that Manuel Chakravarty had some Mac related patches for LLVM, don't know if they have been integrated yet. On 9 April 2010 23:11, Max Bolingbroke wrote:

Hi Haskell-Cafe, I can't get the LLVM bindings for Haskell to install. Does anyone know what I might need to do? Has anyone seen this error before? Here's the problem: (Installing from latest darcs source)

I just tried this on my Mac and got the same problem. The problem is described in config.log:

""" configure:3659: g++ -o conftest -g -O2 -I/usr/local/include  -D_DEBUG -D_GNU_SOURCE -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS  -m32 -L/usr/local/lib  -lpthread -lm    conftest.c -lLLVMCore -lLLVMSupport -lLLVMSystem  >&5 ld: warning: in /usr/local/lib/libLLVMCore.a, file is not of required architecture ld: warning: in /usr/local/lib/libLLVMSupport.a, file is not of required architecture ld: warning: in /usr/local/lib/libLLVMSystem.a, file is not of required architecture Undefined symbols:  "_LLVMModuleCreateWithName", referenced from:      _main in cc5D6X0z.o """

So perhaps LLVM needs to be built universal or something?

problems with ghc-pkg.  I think we need to rebuild LLVM forcing 32-mode, but I haven't yet found the results of this. I'd love to hear what you did if you manage to get it going and compile programs.

My LLVM checkout was still recompiling when I sent that email, but it's now finished and it fixed the problem. All you need to do is compile LLVM as follows: $ UNIVERSAL=1 make Then "make install" the result. That made the LLVM bindings configure and compile fine for me. Cheers, Max

To actually build the examples, I also needed to remove references to the addCondPropagation optimization pass. I don't know why. I attached the darcs patch I'm using. Aran On Sat, Apr 10, 2010 at 4:42 PM, Aran Donohue wrote:

UNIVERSAL=1 worked for me too. Is there a way for cabal install to detect if LLVM wasn't built with this required flag and give a more informative error message?
