我最近完全搞砸了GCC，試圖讓它與openMP一起工作。現在，GCC甚至不能編譯/運行一個簡單的「helloworld」程序。當我輸入「gcc helloworld.c -o Result」時，它給了我一個「ld：library for -lgcc」的錯誤。是否可以從我的Mac中完全刪除GCC？如果是這樣，我該怎麼做？
我每次嘗試安裝gcc /通過執行類似 GCC通過--without-multilib的重新安裝GCC，它給了我這樣的事情：
==> Reinstalling gcc with --without-multilib
==> Downloading http://ftpmirror.gnu.org/gcc/gcc-5.3.0/gcc-5.3.0.tar.bz2
==> Downloading from http://open-source-box.org/gcc/gcc-5.3.0/gcc-5.3.0.tar.bz2

爲了解決這個問題，是有辦法完全刪除GCC，然後再安裝一次？或者有其他解決方案嗎？請幫幫我！
您使用的是xcode嗎？如果您卸載/重新安裝xcode，我相信GCC安裝包含在xcode目錄結構中。無論如何，它在我的機器上。 – LuvnJesus
@LuvnJesus yup！只是卸載Xcode，顯然GCC仍然在這裏根據「gcc --version」 – somanyerrorswhy
