macOS上的OpenMP/gcc:gcc --without-multilib不可用 [英] OpenMP/gcc on macOS : gcc --without-multilib not available

问题描述

去年，我有一个学校项目，该项目使用OpenMP API进行并行计算.我用Homebrew(brew)工具安装了gcc-6 --without-multilib.它像魅力一样运作.

Last year I had a school project that used the OpenMP API for parallel computing. I installed gcc-6 --without-multilib with the Homebrew (brew) tool. It worked like charm.

今年，由于软件问题，我不得不进行全新的macOS High Sierra全新安装.现在，我似乎无法在没有带有brew的multilib的情况下安装gcc.当我键入" brew info gcc "时，我会看到不同的安装标志，并且在此列表中未显示的是-without-multilib . (我尝试了gcc @ 5，@ 6和@ 7).

This year I had to make a new clean install of macOS High Sierra because of a software issue. Now I can't seem to install gcc without multilib with brew. When I type "brew info gcc", I can see the different install flags, and --without-multilib in not in this list. (I tried gcc@5, @6 and @7).

我尝试安装带有必要标志的gcc(以防万一没有"brew gcc info"文档，没有运气.

I tried installing gcc with the necessary flag (in case it just wasn't documented with "brew gcc info", with no luck.

如果有人有解决方案，我很乐意对其进行测试.

If anyone has a solution, I'd be happy to test it.

谢谢， Clovel

推荐答案

稍作更新.似乎安装gcc 7.0及更高版本可以解决此问题，而无需使用--without-multilib选项.看起来OpenMP支持现在是本地的.

Just a little update. It seems that installing gcc 7.0 and beyond solves the problem, w/o the --without-multilib option. It looks like OpenMP support is native now.

它确实为我解决了这个问题. 不要忘记更新brew，并检查您使用的编译器是否正确.

It did solve the issue for me. Do not forget to update brew, and check that the compiler you ar eusing is the correct one.
