首先感谢您帮助我解决与 cabal xD 的灾难...

我正在使用 OS X El Capitan 10.11.3，64 位。

我从 2013 年 5 月的 2013.2.0.0 的https://www.haskell.org/platform/prior.html安装了 Haskell 平台，特别是因为我需要使用 ghc 7.6.3

然后当我执行 cabal update 时......我的头痛开始了......

这只是 binary-0.8.2.0 中的一个错误。

src/Data/Binary/Get/Internal.hs:403:3:
     error: invalid preprocessing directive
     #-}
      ^

src/Data/Binary/Get/Internal.hs有一行以 开头#，clang 的 C 预处理器不喜欢这行。gcc 没问题，但在 Mac 上 Apple 的 gcc 真的很铿锵。

该行是在 12 月 20 日发布的 binary-0.8.0.0 中的新行。很奇怪，显然还没有其他人遇到过这个问题。

我提出了一个问题。

这是使用带有现代 clang 的旧 GHC 版本（现代 Mac OS X 附带）的结果。GHC 使用 clang 进行 CPP，clang 对它的输入不是很了解。

较新的 GHC 没有这个问题，这就解释了为什么它直到现在才被发现和修复。

该问题已在 github 上报告。我已经修好了并推了binary-0.8.2.1。运行并重cabal update试。

如果您遇到任何其他问题，请告诉我binary。
