如何处理"c:错误:不支持的选项'-fopenmp'"；在特拉维斯? [英] How to deal with "clang: error: unsupported option '-fopenmp'" on travis?

问题描述

我目前正在尝试使用 openmp 部署项目.我在Travis上有标志'-fopenmp'.

I am currently trying to deploy a project using openmp. I have the flag '-fopenmp' on Travis.

我该如何解决?

在本地，我只需 brew安装libopenmp 即可解决此问题.但是在Travis上没有，有什么选择?

In local I just brew install libopenmp which solved the issue. But not on Travis, what are the options ?

使用cython，我得到了以下".travis.yml"

Using cython I got the following ".travis.yml"

os: linux

dist: xenial

language: python

python:
  - "3.7"

cache: pip

addons:
  apt:
    packages:
      - patchelf

matrix:
  include:
  - os: osx
    # No version of Python is available via virtualenv on OS X workers, see https://github.com/travis-ci/travis-ci/issues/2312
    language: generic
    env: TOXENV=py37

  fast_finish: true

before_install:
  brew install libomp

install:
  - pip install --upgrade "pip < 19.1" -r CI/requirements.txt
  - python setup.py develop

script:
  - pytest

Travis在执行时失败:

Travis fails while executing :

在本地使用 python 3.7 进行编译时，该如何解决呢?

While in local it compiles with python 3.7, how could I fix that aswell ?

推荐答案

在苹果的 llvm 上，不支持 -fopenmp .一个人应该使用brew的 llvm .

On apple's llvm, -fopenmp is not supported. One should use brew's llvm.

以下能够链接 openmp 的

 - brew install llvm libomp
 - export CPP=/usr/local/opt/llvm/bin/clang;
