Xcode 6中的OpenMP支持（clang 3.5） [英] OpenMP support in Xcode 6 (clang 3.5)

问题描述

xcode 6基于clang 3.5;
on osx 10.9.5运行 clang ++ --version 从命令行报告

xcode 6 is based on clang 3.5; on osx 10.9.5 running clang++ --version from the command line reports

 Apple LLVM version 6.0 (clang-600.0.51) (based on LLVM 3.5svn)

所以我认为苹果包括openmp支持，因为在clang 3.5发行注释

so I supposed that Apple included openmp support given the fact that in the clang 3.5 release notes

http://llvm.org/releases/3.5.0/tools/clang/docs/ReleaseNotes.html

clang开发人员声明部分openmp支持。但是似乎-fopenmp参数仍然无法识别。

the clang developers claim partial openmp support. But it seems that the "-fopenmp" argument is still not recognized.

任何提示？

推荐答案

Clang仍然不完全支持OpenMP，实际上它只支持解析/ Sema分析+'omp parallel'和omp simd指令。您可以尝试通过添加-Xclang -fopenmp = libiomp5选项来激活它。

Clang still does not fully support OpenMP, actually it supports only Parsing/Sema analysis + some basic coidegen for 'omp parallel' and 'omp simd' directives. You can try to activate it by adding -Xclang -fopenmp=libiomp5 options.
