GHC/GCC 编译器问题 __STDC_VERSION__ w/ C99 来自 Stg.h，每个包都失败

Question

每当我尝试在 OSX 10.12.6 和 GCC 4.8.0 上安装带有 cabal(2.0.0) 的软件包时，我都会遇到以下关于 Stg.h 文件的错误GHC 8.2.1，错误非常神秘。我无法在 OSX 上安装任何软件包。

预期行为：

cabal install $packagename 应该在 OSX 上安装 $packagename，因为 cabal 和 cabal-install 已正确安装。

观察到的行为：

cabal install $packagename 由于与名为 __STDC_VERSION__ 的变量相关的低级 GHC/GCC 问题而失败。我不是 C 程序员，我不希望我正确安装 GHC 和 cabal 无法安装软件包。 AFAICT 此问题与用户错误无关。

Answer 1

the error is incredibly cryptic

其实看起来很清楚:

error: #error __STDC_VERSION__ does not advertise C99 or later

C 头文件Stg.h 正在使用标准宏__STDC_VERSION__ 检查编译器是否支持C99（标准ISO C 的1999 版本）。由于未相应设置，编译器不符合 C99，C 源代码会触发错误。

基本上，Stg.h 拒绝使用甚至不支持 18 年前的 C 标准的 C 编译器进行编译。挺有道理的。

GCC 4.8 确实看起来很古老：最新的 GCC 是 7.1。如果不是最新版本，我会尝试将 GCC 升级到更新版本。

更新：正如 Keith Thompson 在下面指出的那样，GCC 4.8，尽管它已经很老了，但如果通过标志 -std=c99，则可以支持 C99。应该有某种方法可以指示 cabal 将此标志传递给 gcc，但我不记得如何。为此，应该有一些名为 cflags 的选项，somehwere.
