I build travis CI jobs on Mac OS because that's the easiest way to get a reasonably modern c++ compiler. I'm glad somebody realizes there's life beyond c++-03

Why can't you just run Clang on Linux? Surely its C++11 and later features aren't exclusive to macOS? Or are you talking about some other compiler?

Travis is still on Ubuntu 14.04, but that ships with clang 3.4 and gcc 4.8, both of which support C++11 just fine, so yeah, I'm confused why 'ksherlock needs macOS. clang 3.4 even supports C++14 (gcc needs version 5; also you might want gcc 5 for the C++11 ABI changes to std::string and std::list).
'ksherlock, if you really want a newer compiler, I'd use http://apt.llvm.org/ . Specifically do something like
sudo: required
before_install:
- curl https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
- echo "deb http://apt.llvm.org/trusty/ llvm-toolchain-trusty main" | sudo tee /etc/apt/sources.list.d/llvm.list
- sudo apt-get update
- sudo apt-get install clang-6.0
Alternatively I think you can do it like this without sudo: required:
addons:
apt:
sources:
- llvm-toolchain-trusty-5.0
packages:
- clang-5.0
For those curious about the setup, we have our own infrastructure that runs a custom in-memory Linux-based OS called Build OS[3] that performs build tasks in throw-away VMs (KVM). This is used for all targets, including Mac OS (though we have to run Mac OS builds on a bunch of Mac Mini's due to Apple's licensing restrictions).
