在Mac上使用自制软件安装带有OpenMP支持的gcc不起作用 [英] Installing gcc with OpenMP support on Mac using homebrew has no effect

问题描述

安装gcc与openMP支持的方式 OSX正在使用自制软件。但是，当我遵循

的常用指令时，请重新安装gcc --without-multilib

它给了我一个警告，说明没有与 - without-multilib 选项相对应的公式，因此这将不起作用。因此，在重新安装过程之后，我没有openMP支持。这里是详细的终端输出。

  poulin8：02-prange-parallel-loops poulingroup $ brew --version 
 Homebrew 1.3.6 
 Homebrew / homebrew-core（git revision b5afc; last commit 2017-10-27）
 poulin8：02-prange-parallel-loops poulingroup $ brew重新安装gcc --without-multilib 
 ==>重新安装gcc 
警告：gcc：这个公式没有--without-multilib选项，所以它会被忽略！ 
 ==>正在下载https://homebrew.bintray.com/bottles/gcc-7.2.0.el_capitan.bottle

One way of installing gcc with openMP support on OSX is using Homebrew. However, when I follow the usual instruction of

brew reinstall gcc --without-multilib

It gives me a warning that there is no formula corresponding to the --without-multilib option and hence this will have no effect. Consequently, I do not have openMP support after this reinstallation process. Here is the detailed terminal output.
poulin8:02-prange-parallel-loops poulingroup$ brew --version
Homebrew 1.3.6
Homebrew/homebrew-core (git revision b5afc; last commit 2017-10-27)
poulin8:02-prange-parallel-loops poulingroup$ brew reinstall gcc --without-multilib
==> Reinstalling gcc 
Warning: gcc: this formula has no --without-multilib option so it will be ignored!
