來自Stg.h的GHC / GCC編譯器問題__STDC_VERSION__ w / C99，對於每個軟件包均失敗

Question

每當我嘗試在OSX 10.12.6和GCC 4.8.0上安裝帶有cabal（2.0.0）的軟件包時，都會遇到以下有關GHC 8.2.1中Stg.h文件的錯誤，該錯誤是難以置信的。 我不能在OSX上安裝任何軟件包。

預期行為：

cabal install $packagename應該在OSX上安裝$packagename ，因為cabal和cabal-install已正確安裝。

觀察到的行為：

cabal install $packagename由於與名為__STDC_VERSION__的變量有關的低級GHC / GCC問題而__STDC_VERSION__ 。 我不是C程序員，並且我不希望正確安裝GHC和cabal會導致安裝包失敗。 AFAICT此問題與用戶錯誤無關。

Answer 1

該錯誤是難以置信的

實際上，它看起來很清楚：

error: #error __STDC_VERSION__ does not advertise C99 or later

C頭文件Stg.h正在使用標准宏__STDC_VERSION__檢查編譯器是否支持C99（標准ISO C的1999版本）。 由於未相應設置，因此編譯器不符合C99，並且C源代碼觸發錯誤。

基本上， Stg.h拒絕使用甚至不支持18年歷史的C標准的C編譯器進行編譯。 相當合理。

GCC 4.8確實看起來很古老：最新的GCC是7.1。 我會嘗試將GCC升級到更新的版本，如果不是最新版本的話。

更新：正如Keith Thompson在下面指出的那樣，盡管GCC 4.8 -std=c99年限，但如果傳遞標志-std=c99 ，它仍可以支持C99。 應該有某種方法指示cabal將此標志傳遞給gcc ，但我不記得如何。 應該有一些為此選項命名的選項，例如cflags 。
