cabal 更新期间出现很多错误，最后无法正常工作

Question

首先感谢你帮助我解决了 cabal xD 的灾难...

我正在使用 OS X El Capitan 10.11.3，64 位。

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

然后当我执行 cabal update 时...我开始头疼...

Failed to install binary-0.8.2.0
cabal: Error: some packages failed to install:
binary-0.8.2.0 failed during the building phase. The exception was:
ExitFailure 1

我的 ghc --version 是 The Glorious Glasgow Haskell 编译系统，版本 7.6.3
我的 cabal --version 是 cabal 安装版本 1.16.0.2 使用 Cabal 库的 1.16.0 版

感谢关注

Answer 1

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，这是 clang 的 C 预处理器不喜欢的。 gcc 没问题，但在 Mac Apple 的 gcc 上确实很笨拙。

该行是 new in binary-0.8.0.0，于 12 月 20 日发布。很奇怪，显然还没有其他人遇到过这个问题。

我提交了 issue.

Answer 2

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用clang做CPP，clang对它的输入不是很了解

较新的 GHC 没有这个问题，这就是为什么直到现在才发现并修复它的原因。

issue was reported github。我已经修复它并推送 binary-0.8.2.1。运行 cabal update 再试一次。

Let me know 如果您运行遇到 binary 的任何其他问题。

Answer 3

总之，最新版本的cabal 1.22.07不能与旧版本的GHC 7.6.3一起使用，因为

It's just a bug in binary-0.8.2.0.

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

src/Data/Binary/Get/Internal.hs has a line that starts with #, which clang's C preprocessor doesn't like. gcc is fine with it, but on a Mac Apple's gcc is really clang.

by Reid Barton

重要的是要知道...

GHC uses clang for CPP, and clang is not very understanding about its input. Newer GHCs don't have this issue, which explains why it hasn't been found and fixed until now.

The issue was reported on github.

感谢您的每一个回答。

PD：我可以使用 Debian 安装 GHC 7.6.3 和 Cabal 1.22.07...>.<
