Macos OSX:已安装到clang的gcc链接

我已经安装了

gcc

和

g++

安装：

$ which gcc
/usr/bin/gcc

$ which g++
/usr/bin/g++

$ brew install gcc
Warning: gcc-6.2.0 already installed

我将通过自制软件重新安装

gcc

：

$ brew reinstall gcc --without-multilib

然后

这个重定向发生了什么？如何使用

gcc

/

g++

尽管涉及到这一点，但它并不是关于

OpenMP

brew

在

/usr/local/bin

中安装工具。使用

/usr/local/bin/g++6

：

$ /usr/local/bin/g++-6 --version
g++-6 (Homebrew gcc 6.2.0) 6.2.0

是的，你是对的。升级gcc修复了它，我在这两个方面都遇到了类似的错误。

$ /usr/bin/g++ openmp.cpp -fopenmp
clang: error: unsupported option '-fopenmp'
clang: error: unsupported option '-fopenmp'

$ /usr/local/bin/g++-6 --version
g++-6 (Homebrew gcc 6.2.0) 6.2.0
