Question

我正在尝试使用：

安装Haskell regex-pcre库

cabal install --extra-include-dirs=/usr/local/include \
              --extra-include-dirs=/usr/include regex-pcre

但是我得到了这个奇怪的错误：

cabal: Error: some packages failed to install:

ExitFailure 1

它的要点似乎是找不到第二个float.h文件：

/usr/include/float.h:8:24: error: float.h: No such file or directory

我打开了/usr/include/float.h，第8行读了：

#include_next <float.h>

我已经在谷歌上搜索了，虽然我不知道那么多C我觉得我理解那条线应该说什么，但是......我不知道如何真正解决这个问题。我不知道我的系统上还有float.h个文件。

我正在使用的GHC和GCC版本。 GCC来自XCode 4. GHC是32位，但我也尝试过64位版本，结果相同。

$ gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.0.2

OS X版本为10.6.7。

非常感谢任何帮助。

Answer 1

在我看来ticket #5011 - Mac + GHC 7.0.2上的XCode 4无法链接。

这在GHC 7.0.3中得到修复，这将是4月中旬发布的Haskell平台的一部分。

另一种解决方案是降级到2010.2 Haskell平台。

昨天看到这个问题：Can't install OpenGLRaw-1.1.0.1 on OS X

在Mac OS X上安装Haskell库regex-pcre时出现问题
