What is the trick to install this package?

[scan]

I have tried it with a self-built llvm, both the configure and cmake way, I have tried version 2.8 and 2.9, I have tried the ubuntu packages llvm-dev. But with every of these installs, cabal install llvm replied the same way:

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
configure: error: could not find LLVM C bindings
cabal: Error: some packages failed to install:
llvm-0.10.0.1 failed during the configure step. The exception was:
ExitFailure 1

The funny detail is, I've made it work on my home-desktop just recently, with a self-built llvm 2.9. But I have no idea how.

What is the magic trick to get this package to install?

I don't have enough details to help. I just built it on Debian using the system llvm-dev without problems.

I just got this on Ubuntu precise. I'm afraid I lost my config.log, but the problem is that configure.ac tells the test program for LLVMModuleCreateWithName to link with libLLVMSupport.a, which doesn't exist at least on 2.9, so the configure process barfs. You can simply remove this linkage as the function you are probing for is in libLLVMCore.a on both 2.9 and 3.0.

Cheers.

(just occurs to me that this was perhaps once necessary on older versions of LLVM, so perhaps link with it if the without case fails)
