Phoronix: Mir Now Depends Upon C++14

While many open-source projects are still transitioning over to a C++11 code-base, Ubuntu's Mir display server is already moving onto C++14...

Wow. make_unique is trivial to put into your codebase without requiring C++14, see Herb Sutter's blog.

It absolutely is. My current work project builds with -std=c++11, because the default compilers of the current ubuntu LTS releases don't support c++14 yet, but we use make_unique. (That's right, on a current ubuntu LTS, you cannot build Mir any more )

The post you mentioned is here: http://herbsutter.com/gotw/_102/
The source is as simple as

template<typename T, typename ...Args>
std::unique_ptr<T> make_unique( Args&& ...args )
{
    return std::unique_ptr<T>( new T( std::forward<Args>(args)... ) );
}

You can even #ifdef __cplusplus <= 201402L the implementation to ensure that the compiler's implementation is preferred when possible.

any modern compiler supports C++14, I see no harm in this as it enforces that the codebase is built with better compilers.

Last I checked, Mir wasn't targetting any Microsoft platforms.

GNU C++ requires linking to the same version or newer of libstdc++. Which means that if you build software with a newer compiler, you require all of your users to install a newer libstdc++ too. This is annoying.

-static-libstdc++ is your friend.

Users totally appreciate the 600kb binary size increase.

do you have any tips for setting up mir on an amiga?

really people still care about anything less then 1MB of space?
I could trow away 100GB right now and still have more then 1TB of free space -.-
