在OSX上使用openMP支持安装gcc的way正在使用Homebrew。但是,当我遵循
的通常说明时 brew reinstall gcc --without-multilib
它向我发出警告,表示没有与--without-multilib
选项对应的公式,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)

==> Reinstalling gcc
Warning: gcc: this formula has no --without-multilib option so it will be ignored!

将omp.h
包含在文件中并进行编译后,我收到错误

有人可以帮我在OSX上使用openMP支持安装gcc吗?

如果你可以用clang代替gcc我可以很容易地编译OpenMP程序。我构建了最新版本的LLVM / clang并使用自制程序通过brew install libomp
安装libomp。
完整步骤如下:
mkdir omp_clang && cd omp_clang
git clone https://github.com/llvm-mirror/llvm.git -b release_60
git clone https://github.com/llvm-mirror/clang.git llvm/tools/clang -b release_60
mkdir build && cd build
cmake ../llvm
make
brew install libomp
./bin/clang -fopenmp=libomp ~/openmp_program.c
