在clang的travis上使用不同的libc++版本
在clang的travis上使用不同的libc++版本
提问于 2017-08-30 02:36:00
Travis使用Ubuntu Trusty，默认的libc++版本是svn199600。
但是，我想使用不同的(较新的)版本进行测试，因为我已经使用不同的clang版本进行了测试。
我当前的.travis.yml如下所示：
language: generic
dist: trusty
sudo: required
matrix:
include:
- env: CXX=g++-7 CC=gcc-7
addons:
apt:
packages:
- g++-7
sources: &sources
- ubuntu-toolchain-r-test
- llvm-toolchain-precise
- llvm-toolchain-precise-3.9
- llvm-toolchain-precise-3.8
- llvm-toolchain-precise-3.7
- llvm-toolchain-precise-3.6
- sourceline: 'deb http://apt.llvm.org/trusty/ llvm-toolchain-trusty-4.0 main'
key_url: 'http://apt.llvm.org/llvm-snapshot.gpg.key'

- libc++-dev
sources: *sources
script:
- ./build_and_test.sh
before_install:
- ./before_install.sh例如，用libc++-dev-3.9替换libc++-dev没有帮助(仍然使用旧的库版本)，即使添加以下行也是如此：
- sourceline: 'deb-src http://apt.llvm.org/trusty/ llvm-toolchain-trusty-3.9 main'我还尝试将以下内容添加到我的before_install.sh中，但没有成功(仍然是旧库)：
sudo apt-add-repository "deb http://llvm.org/apt/trusty/ llvm-toolchain-trusty-3.9 main"
sudo apt-get update
sudo apt-get install -y libc++-dev libc++-helpers libc++1 libc++abi-dev lldb-3.9如果不从源代码构建，如何才能正确完成？

如果不从源代码开始构建，就不可能做到这一点。range-v3库使用a script来做这件事。
我也调整了我的travis.yml来使用它：
