Travis CI 与 C++14 和 Linux

2022-01-12 00:00:00 continuous-integration makefile travis-ci c++ c++14

类似:Travis CI 与 Clang 3.4 和 C++11

如何让 Travis CI 与 C++14 一起工作?

How does one get Travis CI to work with C++14?

这是我们当前的 .travis.yml 文件:

Here is our current .travis.yml file:

language: cpp
compiler:
 - gcc
 - clang
os:
 - linux
 - osx
script:
    make main

这是我们的makefile

# Factor Pro

# Macros
CXXFLAGS = -Os -std=c++14

# Rules
all::main

main: main.cpp
    g++ -o main $(CXXFLAGS) main.cpp

clean:
    rm -rf *.o main

它适用于 osx，但不适用于 linux.

It works on osx, but not linux.

推荐答案

默认的 GCC 和 Clang 版本已经过时了，你需要像这样手动安装更新的版本:

The default GCC and Clang versions are horribly outdated, and you'll need to install newer versions manually like this:

language: generic
os: osx
matrix:
  include:
    - os: linux
      env: COMPILER_NAME=gcc CXX=g++-5 CC=gcc-5
      addons:
        apt:
          packages:
            - g++-5
          sources: &sources
            - llvm-toolchain-precise-3.8
            - ubuntu-toolchain-r-test
    - os: linux
      env: COMPILER_NAME=clang CXX=clang++-3.8 CC=clang-3.8
      addons:
        apt:
          packages:
            - clang-3.8
          sources: *sources

您可以安装多个版本的 Clang 和 GCC，例如 this.

You can install multiple versions of Clang and GCC like this.

注意:我使用的是 language: generic，因为如果 language: cpp，TravisCI 的 CC 和 CXX 已经过时了 覆盖每个单元格的导出，它更快.

Note: I'm using language: generic, because if language: cpp, TravisCI's horribly-outdated CC and CXX override per-cell exports and it's faster.

我也推荐你使用

    $(CXX) -o main $(CXXFLAGS) main.cpp

因为 C++ 编译器在现实世界中几乎从不 g++.

Because the C++ compiler is almost never g++ in the real world.
