我现在使用的是LLVM 2.9，在ghc 7.0.4上运行绑定llvm-0.9.1.2而我只是其中一个错误：

/home/jfmiller28/.cabal/lib/llvm-0.9.1.2/ghc-7.0.4/libHSllvm-0.9.1.2.a(Scalar.o): In function `sm03_info':
(.text+0x24d): undefined reference to `LLVMAddLoopIndexSplitPass'
collect2: ld returned 1 exit status

我为haskell LLVM绑定收到以下链接器错误：

ghc --make hello.hs：

module Main where

import Data.Word

import LLVM.Core
import LLVM.ExecutionEngine

bldGreet :: CodeGenModule (Function (IO ()))
bldGreet = withStringNul "Hello, JIT!" (\greetz -> do
    puts <- newNamedFunction ExternalLinkage "puts" :: TFunction (Ptr Word8 -> IO Word32)
    func <- createFunction ExternalLinkage $ do
      tmp <- getElementPtr0 greetz (0::Word32, ())
      _ <- call puts tmp -- Throw away return value.
      ret ()
    return func)

main :: IO ()
main = do
    initializeNativeTarget
    greet <- simpleFunction bldGreet
    -- greet

    return ()

LLVM与apt-get一起安装到/ usr / lib / llvm。

Answer 1

原始问题的答案是我有一个太旧的LLVM版本。撰写本文时，您需要LLVM 2.8或更高版本。

下一个问题与llvm绑定中的过时行有关。这次的解决方案是从git存储库编译llvm绑定。如果我错了，请纠正我，但我需要更新的cabal install llvm公开的0.9.1.2版本。

请参阅https://github.com/bos/llvm/issues/2和https://github.com/bos/llvm/pull/3

也许这个补丁可以使用LLVM 2.9运行，并在ghc 7.0.4上运行绑定llvm-0.9.1.2
