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) llvm-haskell aran$ cabal install Resolving dependencies... ...snip... checking for unistd.h... yes checking llvm-c/Core.h usability... yes checking llvm-c/Core.h presence... yes checking for llvm-c/Core.h... yes checking for LLVMModuleCreateWithName in -lLLVMCore... no configure: error: could not find LLVM C bindings cabal: Error: some packages failed to install: llvm-0.7.0.1 failed during the configure step. The exception was: exit: ExitFailure 1 I've got the latest LLVM (from source) installed using the default "sudo make install", i.e. into /usr/local. Using cabal install --configure-option --with-llvm-prefix=/usr/local doesn't change the result. LLVM is indeed based in /usr/local. The binaries are in /usr/local/bin/, libLLVM*.a is in /usr/local/lib, etc. Google just shows that this error has cropped up a couple times before. I tried manually disabling the check in the configure script but then generating code fails with massive run-time errors that look like link problems. I'm on an up-to-date Snow Leopard, using the latest llvm bindings from darcs, cabal-install 0.8.0, cabal library 1.8.0.2, ghc 6.12.1, and LLVM from svn. LLVM works fine from C++, at least. I worked through the Kaleidoscope tutorial and a few hand-coded .ll files without a hitch. Have you seen anything like this before? Any tips or things to try? I can't think of what magic setting I'm missing. Thanks, Aran
